EPA flags sewage discharges as a major pollution issue--Connecticut officials requested federal help after sewage from Massachusetts facilities continued flowing downstream. EPA calls it a “major pollution concern.” The practice of dumping wastewater from sewage treatment plants into the Connecticut River has been going on for more than a century. But in recent years, according to Connecticut officials, Massachusetts is more to blame for releasing untreated material - sometimes raw sewage - that could have harmful impacts on people and wildlife downstream.

Hydrilla invasive‑plant management threatened-- Federal funding cuts may limit herbicide‑based efforts to control Hydrilla, an invasive plant choking parts of the river. A survey done in 2021 indicated that about 1,000 acres of the Connecticut River was covered in the grass during its peak growth period in the summer months. Unfortunately, it also spreads very fast, and through boat transmission, it has also spread to a number of lakes around Connecticut. More information.
