TRENTON, N.J. — New Jersey’s largest drinking water supplier discovered a toxic chemical in the river where it gets water for hundreds of thousands of customers, setting off a major search for polluters that led back to a Pennsylvania wastewater treatment plant and a South Jersey company.

The chemical New Jersey American Water Co. found, 1,4-Dioxane, is a byproduct of plastic manufacturing that is considered a likely carcinogen by the federal government. -
