Water in dozens of Philadelphia schools contaminated with lead, report finds

• Potentially tens of thousands of students exposed to toxins
• Report's authors say findings just the tip of the iceberg'

Dozens of schools in Philadelphia are suffering from lead contamination in their water lines, an environmental report has found, potentially exposing tens of thousands of students to toxins proven to cause learning and behavioral issues as well as health problems including damage to internal organs.

The Philadelphia school board disputes the findings of the study by PennPirg (Pennsylvania public interest research group), insisting that systems are in place to prevent students and staff drinking contaminated water, and that any outlet found with lead in excess of acceptable limits is immediately shut down.
