U.S. Environmental Protection Agency Administrator Gina McCarthy was back in Connecticut Tuesday. McCarthy is a former Connecticut environmental commissioner. She spoke with reporters following a visit with environmental advocates and students at an aquaculture school in New Haven.
McCarthy said Connecticut has made progress in reducing the amount of nitrogen its wastewater treatment plants are releasing into Long Island Sound. Nitrogen causes low oxygen dead-zones in the Sound each summer. But McCarthy said nitrogen flowing down rivers and into the Sound remains a problem.
