As we first told you last week, a contaminated site at 145 High Ridge Avenue in Ridgefield, once home to a dry cleaner, is under heightening scrutiny as neighbors now call for a cleanup. According to DEEP, chemicals used for decades threaten local air and water quality, with testing revealing hazardous levels in nearby homes. A developer is working on remediation, but a cleanup plan is still in development. Nearby residents have 30 days to share comments with state officials.
