Investigator Bob Bowcock, an environmental expert associated with environmental activist Erin Brockovich, said trichloroethene from the 1970 Lehigh Valley Railroad derailment site has not migrated toward the Le Roy Junior-Senior High School, The Buffalo (N.Y.) News reported Sunday.
"This is good news," Bowcock stated in a news release. "It is one of the many areas we are investigating where we are able to re-prioritize so we can focus our attention and resources on other environmental concerns."
Teenage girls at the school have come down with a strange illness with Tourette's-like symptoms.
Bowcock said his investigation is looking at multiple environmental concerns, including the natural gas wells on the school grounds, fill material used at the school, the routine complaints of fumes or odors in the school vent system, the storm water system and sports field biological and chemical concerns.
