Sewage Discharge Debate Intensifies Along Connecticut River

SUFFIELD, CT — Cross-border concerns over sewage discharges into the Connecticut River are intensifying, as officials from Connecticut and Massachusetts continue a series of meetings aimed at curbing upstream pollution.

For the third time in less than six months, State Rep. Tami Zawistowski joined Holyoke Mayor Joshua Garcia, Massachusetts State Rep. Pat Duffy, and a growing coalition of local and regional stakeholders to address combined sewer overflow discharges flowing downstream into Connecticut communities.

Zawistowski said the working group is beginning to shift from identifying problem areas to building a coordinated response.

“Since our initial meeting only a few short months ago, this small but growing ad hoc group has made substantial progress toward identifying both primary and secondary areas of concern and is beginning to develop a forward-thinking plan,” she said. “The Connecticut River is a vital resource for both our states' communities, economy, and environment that must be protected.”

Meeting Held In Suffield As Coalition Expands

The latest discussion took place at Suffield Town Hall and via Zoom, bringing together a mix of elected officials, planners, and environmental advocates from both states.

Participants included Suffield First Selectman Colin Moll, representatives from the Pioneer Valley Planning Commission, Mass Audubon, the Connecticut River Watershed Partnership, and Save the Sound, along with other regional stakeholders focused on water quality and conservation.

Officials say the group has steadily expanded as awareness grows around the impact of upstream discharges on downstream communities.

Focus Shifts To Funding, Regional Coordination

With the issue now clearly defined, discussions are turning toward solutions — including identifying state and federal funding sources to address the high cost of infrastructure upgrades needed to reduce or eliminate combined sewer overflows.

Participants also discussed expanding engagement with additional officials in Connecticut, Massachusetts, New York, and at the federal level, signaling the multi-state scope of the issue.

Garcia proposed developing an interactive map to better illustrate which communities are impacted along the river, using data to highlight both environmental and economic stakes.

Tourism, Recreation Seen As Part Of Solution

Beyond infrastructure, the group is also looking at ways to elevate public awareness and economic interest in the river.

Ideas discussed included expanding river-based tourism, promoting paddle events and regattas, and restoring fishing habitats to attract anglers — all aimed at reinforcing the value of a cleaner river.

EPA Defines Scope Of Overflow Issue

According to the U.S. Environmental Protection Agency, combined sewer overflows occur when heavy rain or snowmelt overwhelms municipal wastewater systems, causing untreated stormwater and sewage to discharge into nearby waterways.

These discharges are regulated under the National Pollutant Discharge Elimination System permitting program, though officials say enforcement and infrastructure gaps remain key challenges.

Push For Federal Involvement Continues

The ongoing talks build on a formal request sent in early 2025, when Zawistowski and State Rep. Devin Carney asked the EPA to intervene in addressing upstream pollution entering the Connecticut River.

Officials have cited concerns including public health risks, environmental justice implications, and economic impacts on tourism, recreation, and property values along the river corridor.

The group is expected to continue meeting as it works toward a coordinated, multi-state strategy to reduce discharges and protect the river.
