The DEP has ordered vapor intrusion investigation of certain homes along South Street in New Providence. The testing is a precautionary measure to ensure that vapors from trichloroethylene (TCE) in ground water are not entering any building structures. Lucent technologies conducted similar testing of 19 homes in Berkeley Heights last year. One home was found to be impacted by vapors, which was remedied by installing a venting system beneath the foundation of the home.
