About Mark R. Cuker

Mark Cuker is one of the foremost environmental litigation attorneys in the country. Some of his high-profile toxic tort cases – most notably the Toms River case have been profiled in books, television news programs and on the internet.

Toms River involved children who were developing cancer at an alarming rate — so high that the New Jersey town was designated a “cancer cluster.” The community demanded answers, and, shepherded by Mark Cuker and his team, they discovered that the town’s drinking water had been polluted by chemicals like styrene-acrylonitrile (SAN) trimer and by-products of dye manufacturing for decades.

  • EPA’s PFAS Action Plan: A lot of hot air, but no clean water
    I attended the announcement of EPA’s much ballyhooed PFAS action plan in Philadelphia today. It is all talk and no action. Nine months after committing to hold polluters accountable by listing PFAS as a hazardous substance and setting an enforceable maximum contaminant limit for PFAS in drinking water, EPA has done…nothing. Seven Months ago, people from Warminster, Warrington and Horsham Townships went to a “listening session” to tell  EPA what needed to be done. People whose families have been ...
