Guest guest Posted February 8, 2002 Report Share Posted February 8, 2002 In January the Denver Post ran a series of articles on indoor toxic gasses from ground water and industrial plumes in Colorado and several other states. The EPA since 1998 has been advising regulators to use the -Ettinger computer model. Evidence uncovered by the Denver Post was that the model underestimated the health threat from toxic gases indoors by failing to identify homes at risk when compared to actual testing of the indoor air. The story in today's Denver Post (Feb 7) www.denverpost.com/toxics reports that a review of the model by EPA scientist Helen Dawson in three key states supports their findings. She reported her findings on 10 neighborhoods in 3 states that had adopted the EPA model. Michigan -- Failed to detect 31 of 36 homes with elevated levels. Connecticut -- Failed to detect 27 of 36 homes. Massachusetts -- Failed to detect 13 of 36 homes. In the original series, the Denver Post reported that Ettinger himself applied the model to the Redfield site. The result was " less than three dozen " homes identified by the model out of a confirmed 310. Today's story plus the previous series, including sidebars, can be found at www.denverpost.com/toxics --------------------- Carl E.Grimes grimes@...
