I saw that you posted about the recent study that showed 3 out of 3 NYC schools tested for PCBs had levels above the federal standards. PCBs were most commonly used in construction materials between 1950 and 1978. During that time period approximately 750 Public Schools were either built or renovated (Here is a link to a list of schools built or renovated in that time period). But the DOE's only response so far is to test two schools next summer.
NYCC joined with the New York Lawyers for the Public Interest to demand that the DOE tests all schools possibly contaminated with PCBs and devise an aggressive plan for remediation.
