The Triple Threat to Long Island's water: Nitrogen, PFAS chemicals, and microplastics in lawn fertilizer!

Some of the most popular lawn fertilizers sold and used on Long Island are polluting our water, contaminating the environment, and jeopardizing our health!

The water on, around and under Long Island and Westchester is being contaminated with sewage, pesticides, pharmaceuticals, oil and gas leaks and... lawn fertilizers!

Some of the lawn fertilizers sold and used on Long Island and Westchester contain sewage sludge with PFAS - a class of toxic “forever” chemicals known to cause serious health problems in humans, and they're clad in a plastic (polymer) coating that breaks down into nano-and microplastics.

The most popular fertilizers also contain high levels of synthetic, water-soluble nitrogen which can lead to harmful algal blooms and fish kills and produce nitrous oxide, a potent greenhouse gas.

This is an easy fix. Ask your lawn and garden retailer or landscaping service for lawn fertilizer with no more than 12% nitrogen and no PFAS or plastic.
