"Chemicals linked to cancer and developmental harm are also released in large quantities into the city’s three rivers."
"PITTSBURGH — More than 50 years after the passage of the national Clean Water Act, industrial polluters still regularly dump toxic chemicals linked to birth defects and cancer into local waterways, according to a new report.
Among major watershed regions nationwide, the Ohio River basin received the largest volume of toxic chemical discharges by weight in 2020, according to the report, published today by the PennEnvironment Research & Policy Center. Other heavily polluted watersheds included the Mid-Atlantic watershed, which encompasses parts of Pennsylvania, New Jersey, Maryland Delaware and New York; and the South Atlantic-Gulf, which encompasses Florida and parts of surrounding states.
The report looked at data from the U.S. Environmental Protection Agency’s (EPA’s) Toxic Release Inventory, which documents self-reported emissions of toxic chemicals from industrial sources across the country. It found that western Pennsylvania’s waterways see particularly large releases of chemicals like compounds of nickel and chromium, which are linked to reproductive harm, including reduced sperm count, birth defects, miscarriages and premature births."
