Reuters: Erin Brockovich Pushes for Disease Cluster Law

Per this Reuters article, Brockovich, testified to the Senate and says she has become an informal reporting agency for those who worry that something in their immediate environment is a health hazard.
"Thousands of Americans contact me every month asking for help and telling me about unexplained diseases in their neighborhood or on their streets," Brockovich told the Senate Environment and Public Works Committee. She offered a map of the United States and Canada she said she put together by plotting these calls geographically, showing calls from almost every U.S. state and several Canadian provinces.
A study by the Natural Resources Defense Council and the National Disease Clusters Alliance reported 42 disease clusters in 13 U.S. states, showing incidence of numerous types of cancer, birth defects and other chronic illnesses."
