For generations, the waters surrounding Long Island have defined its identity — from the wide-open waterfronts of the South Shore to the shellfish beds of the North Shore. But beneath the surface, a quieter transformation is underway.
Environmentalists discuss the future of water quality in Stony Brook Harbor
Improved wastewater infrastructure and healthy shellfish populations are the keys to improving the water quality of Stony Brook Harbor. On Tuesday, Feb. 3, environmental activists and scientists gathered at the Stony Brook Yacht Club for a water quality forum, specifically focusing on Stony Brook Harbor.
Endowed Chair of Coastal Ecology and Conservation and Distinguished Professor at Stony Brook University’s School of Marine and Atmospheric Sciences Christopher J. Gobler spent the last two years monitoring water quality and shellfish populations in locations throughout the Stony Brook Harbor watershed. “We wanted to understand, what is controlling the growth of algae in Stony Brook Harbor?” he said.
Long Island’s fragile drinking water system
Experts explain what lies beneath the surface, and detail the threats to our crucial aquifers
Long Island’s drinking water supply is solely dependent on aquifers. Sarah Meyland, a retired professor at the New York Institute of Technology, spoke about the impacts of chronic water depletion on the region’s water supply.
Smallest low-oxygen 'dead zones' in Long Island Sound since 1987
Low-oxygen areas in Long Island Sound dropped last summer to the smallest footprint recorded in nearly 40 years, according to data from Connecticut’s Department of Energy and Environmental Protection.
"This is great news," said Adrienne Esposito, executive director of Citizens Campaign for the Environment in Farmingdale. "This is what happens when you have reliable funding, meaningful collaboration, strong public support, and good science — all working together."
Down the Drain and Into the Aquifer: Long Island’s Septic Systems Just Got a Major Upgrade
You flush and forget about it. But what goes down doesn’t just disappear. On Long Island, where it ends up has been a problem for decades. Outdated septic systems and cesspools leak pollutants into the groundwater. As a result, these aging systems pose serious threats to drinking water, the environment, public health, and the local economy. It’s been a long fight for change, but on July 23rd, Suffolk County took a huge step toward cleaner water.
Suffolk homeowners to get more money back to replace outdated septic system under new provision
Suffolk County homeowners will soon be able to upgrade to enhanced septic systems that reduce dangerous nitrogen pollution at a higher discounted rate, thanks to a surge of state funding announced Wednesday.
Gov. Kathy Hochul signed a bill Wednesday morning at Suffolk County Community College in Brentwood that increases the reimbursement rate for installation of an enhanced septic system to 75%, or up to $25,000. The governor also announced Suffolk County will receive $20 million in new grant funding it can use toward its Septic Improvement Program that provides homeowners $10,000 grants for the upgrade.

Sen. Kirsten Gillibrand, on Long Island, criticizes proposed National Estuary Program budget cuts
Sen. Kirsten Gillibrand was on Long Island Monday to harshly criticize the proposed $8 million in funding cuts in President Donald Trump’s 2026 budget for the National Estuary Program, which supports clean water initiatives, including those on the Island.
Sen. Gillibrand, local leaders oppose federal funding cuts affecting Peconic Estuar
U.S. Senator Kristen Gillibrand paid a visit to Riverhead on Monday morning to warn about President Donald Trump’s proposed $8 million federal funding cut from the National Estuary Program, which could threaten ongoing efforts to maintain and restore the Peconic Estuary and Long Island Sound.
In Riverhead, Gillibrand Sounds The Alarm On The Disastrous $8 Million Cut To National Estuary Program Funding Proposed In FY26 Budget That Would Endanger Americans’ Health
Contaminated water can lead to a plethora of health risks; cutting funding to maintain estuary water quality will endanger Americans’ well-being
Today, U.S. Senator Kirsten Gillibrand sounded the alarm on the proposed $8 million funding cut from the National Estuary Program (NEP) in the president’s FY26 budget. The NEP works to maintain and restore water quality of 28 estuaries across the United States, including the Peconic Estuary and Long Island Sound. Without sufficient funding, the NEP will not be able to monitor New York’s estuaries and keep them safe from threats such as excess nitrogen pollution, pathogens, and harmful algal blooms, which have been shown to be harmful to public health and the environment. Funding to restore and protect our estuaries also boosts coastal resilience from storms, improves tourism and recreation, and supports local jobs.
Assemblywoman Rebecca Kassay’s Clean Water Septic System Bill passes Legislature unanimously
Legislation Expands Access to Modern Septic Systems, Protecting Groundwater and Waterways Across New York
In a major environmental and affordability win, Assemblywoman Rebecca Kassay announced the unanimous passage of her legislation (A8807/S8241-A) in both the New York State Assembly and Senate. The bill updates the reimbursement structure of the New York State Septic System Replacement Fund, making it easier and more affordable for New Yorkers to upgrade to advanced septic systems that significantly reduce water pollution, according to a press release.

Albany, NY – New York State Senator Pete Harckham, chair of the Senate Environmental Conservation Committee, and State Senator Rachel May hosted a public hearing on May 21 here at the State Capitol to evaluate the efficacy of New York State’s monitoring and management of harmful algal blooms (HABs) and to examine potential legislative solutions.
The ‘elephant in the room’ at Palumbo’s annual environmental roundtable: future of federal funds
Representatives of two dozen organizations gathered Thursday for an annual environmental roundtable meeting hosted by State Senator Anthony Palumbo to discuss regional environmental issues, concerns and needs. The event went off as it does every year: a cordial, free-wheeling, pass-the-mic conversation.
If the ongoing federal staffing cuts and budget-slashing being undertaken by the Trump administration worried the environmental advocates and government officials in the room, their concerns were mostly left unspoken —even though most of the programs addressing local environmental issues substantially rely on federal funding.
