In the 1950s and '60s, a Monsanto production line in Anniston, which closed in 1969, used mercury to produce the raw materials for PCBs. A new chapter expands Calhoun County's pollution story. This time, it's mercury. For more than 30 years, historic mercury discharges in the Anniston community have gone unprobed, an investigation by The Anniston Star found. Industrial-released mercury entered the environment decades ago, but no one is sure how much is out there or where it is. Monsanto Corp.'s chemical plant in western Anniston used mercury and lead, both neurotoxicants, to produce the raw materials for PCBs in the 1950s and '60s. PHOTO: In 1967, the mortality rate of fish in Choccolocco Creek was found to be unnaturally high, but testing did not determine the cause of the deaths. PCBs have since been found in the waterway, shown here south of Friendship Road in Oxford. Before the discovery of PCB and lead pollution in local streams, ditches and low-income neighborhoods, Monsanto operated a caustic soda and chlorine plant that sent as many as 40-50 tons of liquid mercury into its waste stream, company records show. Fifty tons is the equivalent of 10 dump truck loads. Monsanto employees swept mercury spills into drainage ditches leading to the plant's storm sewer, where traps recovered elemental mercury for reuse. Periodically, Monsanto employees cleaned out the mercury ditches and traps, according to documents provided to The Star by Solutia Inc., Monsanto's spin-off company.

Periodically, Monsanto employees cleaned out the mercury ditches and traps, according to documents provided to The Star by Solutia Inc., Monsanto's spin-off company. However, an emulsion of mercury, mercuric chloride and other chemicals also went to the company storm sewer and was not recoverable, according to Jim , a former research chemist who worked at the plant. " Without further treatment, none of the mercury in the emulsion would have been recovered. " " I don't know how you could quantify the losses of that stuff, " said. " It was a primitive system. " There is no evidence to show that Monsanto discharged lead in a similar manner. Today's state officials claim that until 1999 they were not aware that Monsanto had used mercury, yet former state officials were aware of the fact in 1970, Star archives show. In 1999, Monsanto's spin-off Anniston company, Solutia, gave state regulators a brief description of the site's use of mercury. But, company records show that the information Solutia supplied about the potential for mercury discharges was incomplete and inaccurate. Solutia consultants told the Alabama Department of Environmental Management in 1999 that Monsanto used mercury but most likely did not release it to the environment. In a recent interview, Solutia's Dr. Kaley, director of environmental affairs, said, " Is there a discrepancy? Sure. " " Apparently, there was a discharge. " The " discrepancy " is contained in a 26-page letter to ADEM, which was prepared by Solutia's environmental consultants, Blasland, Bouck & Lee, Inc., Kaley said. The consultants did not obtain access to all of the relevant documents, which were " buried deep within the company, " he said. " They only had 30 days to respond. " ADEM now plans to expand its investigation of Monsanto's environmental releases. " Testing will be as comprehensive for mercury and lead as it has been for PCBs, " said Steve Cobb, chief of ADEM's hazardous waste section. Both mercury and lead were used by Monsanto to create the raw materials - chlorine and biphenyl - for its former PCB manufacturing plant, which was one of only two in the country. Company records also show chlorine was used to make parathion, a powerful pesticide now banned by the U.S. government. It is not known to Solutia officials or environmental investigators how Monsanto disposed of all of its lead. The U.S. Environmental Protection Agency is investigating the sources and extent of residential lead pollution in Anniston. Lead is a proven cause of neurological damage and lower intelligence in children. " I doubt that we are the lamp post that should be looked under, " said Kaley, regarding Anniston's lead pollution. The mercury emissions, however, are a revelation, even though they were in company records and documents in the late 1960s, a span of time when mercury was being revealed as an international threat to health. Combined with lead and PCBs - which are still being studied for causes of neurological damage and cancer - mercury adds a third leg to Anniston and Calhoun County's industrial pollution triangle. Methylmercury threat When discharged to water, mercury can convert to a highly toxic organic compound, methylmercury. Methylmercury has been proven to be toxic to humans, causing severe mental and physical disability in large doses and intellectual impairment in chronic, low doses. In 1969, about the same time mercury poisoning was making global headlines for deaths and illness in Japan, Monsanto dismantled its caustic soda-chlorine plant, the source of the mercury discharges. Unlike four other Alabama mercury-emitting plants that came under intense environmental scrutiny in 1970, Monsanto's chlorine plant emissions were not investigated. The plant had closed in 1969. A 1970 fish analysis initiated by the Food and Drug Administration gives reason to hope that local residents were not consuming fish with dangerous levels of methylmercury at that time. J.L. Crockett, director of the technical staff of the Water Improvement Commission reported that all fish tested in Choccolocco Creek contained mercury, but most were below the federal advisory level, according to a July 9, 1970 article in The Star. Crockett acknowledged that Monsanto had operated a " mercury cell " chlorine plant. " I can't say the mercury in this fish came from there or from somewhere else. I think what we do want to convey is that this is not a situation of alarm, " he told The Star in 1970. Neither Jim Warr, director of the Alabama Department of Environmental Management nor Kaley could explain why the plant site was not investigated. Warr, who joined the state environmental commission in 1968, said he wasn't aware that the plant used mercury. " I don't guess I knew that until you just told me, " he said, in a recent interview. Kaley said he didn't know why Monsanto's chlorine plant wasn't investigated for mercury emissions, either, but suggested that it may have been overlooked because it had already shut down. Over two months The Anniston Star has gathered 2,154 documents and conducted more than 50 interviews relating to waste emissions from Monsanto's 1952-built chlorine plant and other manufacturing processes. Monsanto and Solutia company documents and interviews with former Monsanto employees show clear evidence that the Anniston plant released mercury to the environment - to land or water. When asked in 1999 and 2000 to account for historic mercury and lead emissions, Solutia told Alabama regulators there were likely none. Regarding mercury, history and documents tell a different story. Death by effluent In 1967, two biologists saw fish boil in a Monsanto ditch. Belly up in 10 seconds, dead in five minutes. " That was a potent brew, " Dr. recalled. 's story really begins earlier that day, when he and his mentor, the late Dr. Denzel Ferguson, a celebrated Mississippi State University biologist, arrived in Anniston with a truck carrying tanks of healthy bluegill fish. They disembarked near the boundary of the Monsanto plant, near one of the plant's drainage ditches leading to Snow Creek. Looking up, could see the plant on a hill. They loaded 10 bluegill into a cage and lowered the cage into the cement-lined ditch carrying Monsanto's effluent. The clear fluid didn't look dangerous, but the reaction was immediate. " The fish just boiled, " said. " We were both pretty shocked. " , who was then studying for his doctorate at MSU, is now biology department chairman at Middle Tennessee State University in Murphreesboro. He and Ferguson set more fish cages downstream and determined that the lethal effects of the effluent extended into Snow Creek and continued several hundred yards into its receiving stream, Choccolocco Creek. These results were recorded in Ferguson's 1967 report to Monsanto, entitled " Investigations of Certain Pesticide-Wildlife Relationships in the Choccolocco Creek Drainage. " In that report, Ferguson also told Monsanto the cause of the fish fatalities: high acidity and mercury. Lab tests had confirmed a toxic effluent in the drainage ditch, laden with mercuric chloride, an oxidized form of mercury, the same report said. Mercuric chloride, a byproduct of the chlorine plant's manufacturing process, is a powerful poison and suspected carcinogen that can convert to methylmercury in aquatic environments. Methylmercury is responsible for 80 percent of the fish advisories in the United States. Other fish tests also showed extreme results, according to two other members of Ferguson's squad. On one occasion, Mack Finley lowered bluegill into the effluent and watched them actually jump out of their skin. " It just shucked off, like a glove, " said Finley, now a professor of biology at University of Tennessee-sville. Dr. Larry Ludke worked mostly at Choccolocco Creek testing stations. He noted, " There were fish dying almost constantly up and down that creek. It was pretty apparent that there was a constant level of mortality in that stream that wasn't natural. " Monsanto asked them to find out if Monsanto pesticides were killing the fish. Ferguson's team never found out why the fish of Choccolocco were dying in such large numbers - it wasn't pesticides, according to his report. " It could have been a lot of things, " said Ludke, who is now a chief regional biologist in Colorado for the U.S. Geological Survey. During one of his visits to Anniston, a Monsanto official told Ludke about historic mercury losses, he said. " I remember the comment that they had lost quite a bit of mercury. " Also, Ludke and others discovered " massive " peaks of a mysterious compound on their analytical equipment. After showing Monsanto the results, Ferguson's team was able to identify the compound as PCBs. In the final portion of his 1967 report to Monsanto, Ferguson recommended, " Clean up Snow Creek! " A closed loop? Monsanto's PCB releases have been documented since 1970 through letters and meetings, but according to ADEM, it wasn't until 1999 that Solutia Inc. specifically stated to ADEM that the Anniston facility had used mercury. The only references to the mercury process used at the chlorine plant discovered during The Star investigation were found in company documents and 1970 newspaper articles, which include quotations from J.L. Crockett, the late technical director for the Alabama Water Improvement Commission, ADEM's predecessor. In 1998, ADEM asked about potential mercury discharges after receiving a tip from an outside source, said Cobb, ADEM's hazardous waste chief. According to Solutia's Dr. Kaley, the plant's use of mercury should have been " no secret to ADEM. " " There aren't that many other ways to make chlorine. " Kaley said Solutia's environmental consulting firm, Blasland, Bouck & Lee, Inc. (BBL), prepared the 26-page reply, which included the inaccurate statements about Monsanto's mercury emissions. " I don't know who they asked and who they didn't ask. I'm sure they felt they made sufficient inquiries. " Alan Fowler, Solutia's BBL project manager, said BBL concluded that it could not answer ADEM's questions with the information available to them from Solutia and state records. Fowler said because there wasn't complete information, BBL revised the off-site PCB investigation to include a study of mercury as well. Fowler called the study " fairly comprehensive. " However, Cobb said ADEM doesn't have enough information to understand the mercury contamination. ADEM spokesman Bruner said ADEM's first site assessment for Monsanto, issued in 1991 and obtained by The Star, briefly mentioned a caustic soda-chlorine plant operating until 1969. " It did not include the word mercury, " he said. " If that word was in there, we would have done more investigation, " Bruner said. In that era, chlorine-caustic soda plants commonly used and discharged mercury. Even today, chlorine plants are the largest U.S. mercury consumers, according to a 2000 U.S. Geological Survey report. " We probably should have caught that. We did not. At the time, we were concerned about PCBs and pesticides, " Bruner said. After receiving the tip, ADEM required limited testing for mercury in Solutia's initial watershed investigation. Also, ADEM requested a synopsis of all historical information about mercury usage and disposal. In the 1999 reply letter, Solutia's BBL Inc. consultants told ADEM the chlorine plant used mercury, but implied that the company did not discharge it: " While the records are not clear, it appears that chlorine was manufactured between 1952 and 1969 using a mercury cell process. No records could be located describing the consumption of mercury, although it is noted that the process is a closed one in which mercury is recycled and reused. " " That's an outright lie, " said , who worked at the Anniston plant from 1964 to 1968 and briefly returned to Anniston in 1969. " It went to the storm sewer. I saw it, " said . ADEM's Cobb said he was skeptical of the chlorine plant response. " I know that we are looking at that and asking questions. We've never really seen chlorine operations that have a closed loop, " he said. In 2000, because of the lead contamination found in ditches and residential soil near the Solutia plant, ADEM asked Solutia about its lead uses. Solutia documents to ADEM about lead use at the Anniston site said the facility used pots of molten lead from 1928 to 1961 to make biphenyl. Biphenyl is the building block of PCBs and a variety of other chemical compounds, and biphenyl was produced by Monsanto only in Anniston. During The Star investigation, no records were found showing how the company disposed of the lead once it was rendered useless. Solutia's Dr. Kaley said at least some of the lead was probably dumped in landfills or sold. In his Oct. 12, 2000, letter to ADEM, Kaley wrote that the facility used a " tightly-closed " process for its lead pots, which were used to generate heat for the production of biphenyl. The Environmental Protection Agency has taken the lead role in investigating sources for nearby residential lead contamination, and has listed 22 facilities in the western Anniston industrial zone as potential lead polluters. The Anniston Star also used lead in its production processes, but didn't make EPA's list of potentially responsible sites. EPA's residential lead investigation continues, and ADEM also plans to require extensive lead sampling in the local watershed and on the Solutia plant site, Cobb said. Monsanto did not track possible lead emissions, company records clearly show. But it did record its mercury emissions. No rules Two 1967 internal Monsanto memos, written by the late Gene Coley, the plant's environmental officer, discuss measures to study and control mercury emissions to Snow Creek and bury mercury-containing sludge. In a memo dated Jan. 5, 1967, Coley wrote that " work has begun immediately to put into effect a plan to investigate mercury concentrations in Snow Creek at its confluence with Choccolocco Creek, a long-range method for reducing the mercury levels and an immediate means of reducing mercury levels. " At the time, the company took several steps to drastically curtail its mercury losses, according to the memo. Shortly before closing the chlorine plant, Monsanto recorded its maximum mercury waste stream from the Anniston plant at 570 pounds per month, according to the 1968 Monsanto chlorine plant operating manual, obtained by The Star. However, company records did not measure the amount of mercury spills, air emissions or sludge generated in the production process. Solutia's Kaley said it is possible that some mercury escaped in the chlorine plant's air emissions, but it would be impossible to determine how much. He said he does not know how Monsanto disposed of its mercury-containing sludge. " I'm not going to tell you not one molecule escaped, " Kaley said. Former Monsanto chemist Jim said the chlorine plant operated at 90 to 100 percent of its capacity in the mid- to late-1960s. " It was a boom time for organic chemicals, " he explained. At that rate, 45 to 50 tons of mercury, the equivalent of 10 dump truck loads, may have been released to the ditches during the 16-year operation; on the other hand, Coley's memos indicate that Monsanto began to eliminate its mercury emissions in the final two years of operation. Kaley said he does not believe 50 tons were emitted. " I don't think it was anywhere near that, " he said. In 1967, while Coley was writing memos about mercury losses, was working in his laboratory to find a viable way to cycle the mercury back into the manufacturing process. " It was my understanding it was an economic issue, " he said. In a series of interviews with The Star, Monsanto's , who now runs a private consulting firm in Delaware, described the difficulties he faced in his small lab, trying to find a way to reclaim the mercury discharge. " I worked on it, but I could never get it back. " After the decision was made to close the chlorine plant, was asked how to recover spillage from the chlorine plant. " They wanted to contain the mercury from where it was all over the ground. " He advised them, before leaving Anniston in 1968, to build a sump - a pit into which workers could temporarily dump the mercury and then pump it out. " I told them there was no other way to salvage it, " he said. In 1969, Monsanto officials dismantled the plant. briefly returned to Anniston to supervise the transfer of salvaged mercury to Monsanto's headquarters in St. Louis, he said. A small team of employees had recovered thousands of pounds of mercury from the demolished plant, said. " I don't know what happened to what (already) was in the ground, " said. " We loaded the mercury into flasks, and we had it all out of there in two or three days, " he said. The Star reported on Aug. 1, 1969, that 23,000 pounds of mercury, encased in 50-pound metal flasks, were stolen from Monsanto. FBI agents estimated the net worth of the mercury at $250,000. Toxic reaction While it operated, Monsanto's plant was never subject to mercury regulations. Even though a link between acute human poisoning and mercury emissions was proven in 1962, industrial discharges in the United States were not curtailed until 1970. Monsanto's chlorine plant, closed in 1969, just missed the chance for scrutiny. However, before Monsanto phased out its Anniston chlorine plant, international scientists had gathered information about severe toxic effects from mercury in aquatic environments. Beginning with mysterious afflictions of humans and animals in 1956, acute mercury poisoning came to be known in Japan as Minamata Disease. In 1962, the disease was linked to methylmercury, a form of mercury that festers in the environment. In the late 1960s, two scientists, one Swedish and one American, were the first to describe the conversion of metallic mercury to toxic methylmercury in aquatic ecosystems. In 1968, the Japanese government officially accused Chisso Corporation, a chemical manufacturer in Japan's Minamata Bay, of poisoning humans who had consumed polluted fish and water. The company had dumped methylmercury, the most toxic form. By 1968, at least 50 people were dead of mercury poisoning and thousands were sick. The epidemic hit U.S. newsstands in 1972, when LIFE magazine printed an eight-page report, with graphic photographs, about stricken Japanese villagers. For more than 20 years, Chisso's methylmercury impregnated the water and the fish of Minamata Bay. The methylmercury cleanup in Minamata Bay was finally completed in the late 1980s. In 1970, the mercury scare crossed into North America, when mercury-poisoned fish were discovered in a popular recreational lake near a Dow Chemical Co. plant in Ontario, Canada. High mercury levels were also discovered in human hair samples. Soon after the discovery, U.S. industries drastically reduced their mercury discharges. In 1970, Alabama regulators pounced on four Alabama plants, not including Monsanto, which were suspected of mercury discharges. The four plants were Stauffer Chemical Company at LeMoyne, Olin-Mathieson at McIntosh and Diamond Shamrock Company in Muscle Shoals and Mobile, according to Anniston Star records. In several cases, technicians from the Alabama Water Improvement Commission, the precursor agency to ADEM, found high levels of mercury in sediment and fish near the sites. Mercury-poisoned fish were found in the Tombigbee, Mobile, Tensaw and Tennessee rivers, resulting in fish consumption warnings in those rivers, according to 1970 Star articles. ADEM director Warr said he did not know why Monsanto's chlorine plant was not targeted. Warr participated in some of the mercury sampling near the Diamond Shamrock plant near Muscle Shoals, but didn't recall why that facility was targeted or what the results showed, he said. Warr said the state's environmental officers, Crockett and Bolton, who held responsibility for the mercury investigations, are dead. Star records show that after the mercury investigations, several Alabama Water Improvement Commission members recommended a strict standard for mercury waste - zero emissions. But, under pressure from chlorine users, and the approval of the state health officer Dr. Ira Myers, the commission backed off, agreeing to allow the plants to emit as much as a quarter-of-a-pound per day of mercury into state waterways, according to the Star articles. Despite drastic reduction in water discharges, mercury air emissions are still contaminating waters across the world. Currently, industrial emissions in Alabama and neighboring states have resulted in mercury fish advisories on the Fish, Fowl, Mobile and Tombigbee rivers and the entire Gulf Coast. At present, 40 states have mercury fish advisories. Scientists are scratching their heads, trying to find out why elevated mercury levels are emerging, even in areas far from polluting industries. " It's almost creating a perpetual problem, " said Dr. Larry , an environmental chemist and director of the Environmental Sciences Institute at Florida A & M University in Tallahassee. " Once it gets into the aquatic environment, it continues to circulate. " 'I've never heard about a sump' ADEM officials admit that they don't have a handle on the mercury contamination in Anniston. They don't know how and where exactly Monsanto's mercury was disposed or discharged, according to Cobb, chief of ADEM's hazardous waste division. " I've never heard about a sump, " Cobb said, in a recent interview. Solutia's Kaley said he didn't know either, but he noted that a sump, a container pit, is " a perfect way to recover elemental mercury. " Monsanto did operate a PCB sump, he added. Faced with growing evidence that Monsanto may have had a role in mercury and lead discharges in Anniston, ADEM plans more testing on Solutia property and in the watershed, Cobb said. ADEM is less concerned about historic discharges than determining current levels of contamination, Cobb said. " Our first priority is looking for existing contamination. " " In the limited mercury data we have, the numbers aren't that high, " Cobb said. According to ADEM's procedures, Solutia develops its own work plans for testing, which are scrutinized by ADEM personnel for deficiencies. Then, after a potentially lengthy revision process, ADEM approves the plans and Solutia conducts the tests. Sometimes, ADEM participates in the sampling. In previous tests, Solutia has conducted only limited testing for mercury - 10 percent of its soil samples and 50 percent of its fish samples, reported in a 1999 report from Solutia to ADEM. Future testing will be much more extensive, Cobb said, explaining that ADEM will require more comprehensive mercury, PCB and lead testing in a series of studies of the local creeks, the floodplain area and the plant site. " With as little data as we have right now, there are indications of areas we need to look at, " Cobb said. " Looking beyond the plant, we've only scratched the surface, " he said. It's there At least one person was perplexed by elevated levels of mercury he saw in Choccolocco Creek fish. In 1996, Brad McLane of the Alabama Rivers Alliance, a watershed protection group based in Birmingham, gathered statewide fish data from ADEM and plugged it into his computer. His intent was to determine if more Alabama waterways would have mercury fish advisories if the state used the lower safety threshold of .5 parts per million used in neighboring states. " It was pretty obvious there was a problem in Choccolocco, looking at the numbers, " McLane said. " People already were cautioned against eating the Choccolocco fish because of PCBs. It was clear there was mercury, too. " Kaley said, based on available test results, mercury levels at the plant and in the watershed don't currently indicate a mercury problem. The Star hired Dr. Gragg, an environmental toxicologist and policy expert at Florida A & M, to analyze company documents and ADEM reports available from the 1960s to the present. After a 10-hour analysis, Gragg stated that the weight of evidence shows that ADEM should have identified mercury and lead as potentially serious contaminants decades ago simply from the knowledge that Monsanto produced its own raw materials - chlorine and biphenyl - for the PCB manufacturing process. " The question is, why did they take so long to characterize this problem? " Gragg said. " They need to determine the effect on people and the environment, " he explained. " But, by starting 30 years late, they've lost a whole generation of people who may have had health effects. " According to Dr. Bill Fitzgerald, a New England chemist who has studied mercury in the environment for 25 years and is considered one of the top experts in the United States, mercury is similar to PCBs in that it is very persistent in the environment. Although discharged years earlier, it will remain in the watershed - either buried under sediment or still bleeding pollution, said Fitzgerald, a professor at the University of Connecticut. Mercury is one of the heaviest metals. One pound of it will fit in a laboratory test tube. Typically, mercury will attach to sediment at the bottom of a creek, where it will either lie inert or transform into other mercury compounds, such as methylmercury, he said. Whether the mercury " methylates " depends on whether certain bacteria are growing in the water, Fitzgerald said. Today, state-mandated testing shows detectable levels of mercury in fish and sediment in both Snow and Choccolocco creeks. In addition to extremely high levels of PCBs previously recorded in Choccolocco fish, ADEM reports show that as recently as 1993, some creek fish downstream of Snow Creek also exceeded Alabama's 1 part per million advisory for mercury. The 1 part per million benchmark is considered protective of human health by Alabama state health officials. However, federal guidelines recommend that pregnant women and children refrain from eating fish containing .5 parts per million mercury. Since 1993, residents have been cautioned by state health officials against eating Choccolocco fish because of PCB contamination. Although the few samples screened for mercury haven't shown extremely high levels, that doesn't rule out the possibility that methylmercury is a threat, state officials said. " We need to have more testing, " ADEM's Cobb said. In a 2000 report to ADEM, prepared by BBL Inc., Solutia said it detected mercury at all 10 of its soil sampling locations on Choccolocco Creek near Boiling Springs Road. In the same report, Solutia detected mercury in 24 out of 27 sediment samples from Snow Creek. Also, Solutia screened for mercury in 35 of 70 bass fish samples it collected. The remainder were tested for PCBs. The highest mercury concentration found was .91 milligrams per kilogram. That's just below Alabama's fish advisory limit. Solutia reported to ADEM that all of its core, or deep sediment, samples collected in Choccolocco downstream of Snow Creek were scrapped because of a laboratory problem. So, Solutia decided to analyze surface sediment instead. Similarly, eight sediment samples in Snow Creek were also rejected in the lab, according to the Solutia report. " We had some questions about that, " Cobb said. He said Solutia will have to provide new results. " We'll do whatever we're required to do, " Solutia's Kaley said. What made this drag out? For untold years, ditches and streams flowing through western Anniston have carried a heavy load of metals and chemicals. " It was a different environment, then, " said , Monsanto's former research chemist in Anniston. " Back then, we in industry believed the solution to pollution was dilution. " More than a dozen articles published in The Anniston Star in the 1960s tell of thousands of fish and other wildlife dying in Choccolocco Creek and the Coosa River because of industrial spills. At least 10 Star articles from the 1970s and 1980s report local residents choking and complaining during bouts of smelly air pollution. One industry that always got blamed was Monsanto, although it was not the only Anniston facility emitting toxic wastes to air, land and water. Monsanto first began supplying information to Alabama regulators about its pollution in the 1960s, after an extensive fish kill was blamed on parathion, a Monsanto pesticide, said Kaley. After the creation of new hazardous waste regulations in the 1980s, Monsanto built groundwater monitoring wells, began sampling efforts for several of its chemical products and supplied limited information to ADEM about its waste and production areas, ADEM and Solutia records show. In 1986, Monsanto received its first permits for a regulated landfill and an old hazardous waste treatment area. Yet, with permission from the Environmental Protection Agency, Monsanto " representatives declined to disclose past or present annual production volumes or explicit details of their manufacturing processes to avoid divulging confidential business information, " according to a 1991 ADEM report. Under these conditions, Monsanto did not have to tell ADEM much about its mercury, lead or PCBs processes. ADEM personnel duly reported back that " few details were available " regarding the production of chlorine or PCBs. ADEM's Cobb said it is not unusual for a company to withhold information about its production volumes and manufacturing processes. " It's not necessarily a red flag, " he said. Although ADEM has not gathered a measurement for Monsanto's PCB or other environmental releases, Cobb said knowing the " general magnitude " of the problem is sufficient. Florida A & M's Gragg said production volumes, as well as estimates of how much was disposed, would help put the problem in better perspective. Gragg said the paperwork - both on ADEM and Solutia's part - doesn't show that any effort was made to find out how much lead or mercury could possibly be contaminating the environment. Some of that information could have come from studying the amount of PCBs produced, which would have given a hint to how much lead and mercury were actually used, he said. Because Monsanto had officially notified the Environmental Protection Agency about a PCB problem in the 1970s, there has been plenty of time to gauge the level of pollution. " The knowledge of the release of significant amounts of PCBs should have signaled an urgent need to investigate for the presence of the other major manufacture components on-site and off-site, " Gragg said. Mercury was detected on the facility as early as 1987, according to ADEM inspections. In a 1987 report, ADEM observed drinking water violations in Solutia's groundwater for seven pollutants, including one violation for mercury. The other violations: 11 for chlorides, 23 for iron, 20 for manganese, eight for sulfate, two for cadmium and four for lead. In 1991, ADEM again detected mercury in the groundwater. In 1996, ADEM reported that Solutia's groundwater had exceeded its allowable level of concentration for mercury. A 1999 Solutia report indicated higher-than-allowed levels of mercury at several groundwater monitoring locations. ADEM documents show the agency has long been aware of violations at Solutia. Indeed, one letter dated April 22, 1992, from ADEM to the environmental specialist at Monsanto in Anniston about deficiencies in lab testing for pesticides concludes: " Although this is a violation of Monsanto's permit conditions, ADEM will not be forwarding any further enforcement letters belaboring the point. It is hoped that Monsanto's forthcoming major permit modification will adequately address and eliminate this item of concern. " Solutia's Kaley described the groundwater violations for mercury and other constituents since the 1980s as " minor exceptions. " Generally, violations in the groundwater do not result in fines, rather are handled as part of a long-term strategy to combat the pollution with a complex system of monitoring wells and pumps at the plant site, Cobb said. Overall, Gragg said, it is distressing that it took 30 years for mercury and lead to rise to the attention of state authorities. " Where's the sense of urgency? " he asked. PCBs, Lead and Mercury PCBs Polychlorinated biphenyls are mixtures of up to 209 individual chlorinated compounds, invented by Swann Chemical Company and manufactured by Monsanto until 1972. Usage: PCBs have been used as coolants and lubricants in transformers, capacitors and other electrical equipment because they do not burn easily and are good insulators. Health effects and symptoms: PCBs are pervasive in the environment and bioaccumulate in the food chain, causing health advisories for fish and other wildlife in some locations. Exposure to PCBs may cause acne-like skin conditions and rashes and neurobehavioral and immunological changes in children. PCBs are considered a probable human carcinogen by the U.S. EPA. Also, recent studies indicate that eating large amounts of PCB-contaminated fish may impair the memory and learning of adults. Lead A naturally-occurring bluish-gray metal found throughout the environment. Much of it is released from human activities including burning fossil fuels, mining and manufacturing. Usage: Lead has many uses, including the production of batteries, ammunition, metal products (solder and pipes) and devices to shield X-rays. Because of health concerns, lead from gasoline, paint and ceramic products, caulking and pipe solder has been dramatically reduced. Health effects and symptoms: Lead can affect almost every organ and system in your body, whether breathed or swallowed. The most sensitive is the central nervous system, especially in children. Even at low levels, lead poisoning has been linked to reduced growth, aggressive behavior and lower intellect in children. Lead also damages kidneys and the reproductive system. Lead can cause anemia, weakness in fingers, wrists or ankles, and damage the male reproductive system. It may possibly affect the memory. Mercury A naturally-occurring metal with several forms. The metallic mercury is a shiny, silver-white, odorless liquid. If heated, it is a colorless, odorless gas. Mercury combines with other elements, such as chlorine, to form inorganic compounds such as mercuric chloride. Mercury and its compounds may also combine with carbon to make organic mercury compounds, such as methylmercury. Usage: Metallic mercury is used to make chlorine gas and caustic soda, and is also used in thermometers, dental fillings and batteries. Health effects and symptoms: The nervous system is very sensitive to all forms of mercury. Methylmercury and metallic mercury vapors are more harmful than other forms because they reach the brain, potentially causing permanent brain damage or damage to the kidneys. Mercury poisoning can result in irritability, shyness, tremors, changes in vision or hearing and memory problems. Mercuric chloride and methylmercury are possible human carcinogens, according to the EPA. Mercury's harmful effects that can be passed from the mother to the fetus include brain damage, mental retardation, incoordination, blindness, seizures and inability to speak. Children poisoned by mercury may develop problems in the nervous and digestive systems and kidney damage. Quote Link to comment Share on other sites More sharing options...
