A report by the Farmingdale-based Citizens Campaign for the Environment (CCE) reveals elevated levels of a possible carcinogen in water districts throughout Long Island.
Found in various personal-care products, the cancer-causing chemical, 1,4-dioxane, is listed as “likely to be carcinogenic to humans” by the Environmental Protection Agency (EPA). And according to CCE, Long Islander water supplies have the highest levels of 1,4-dioxane in the nation.

In response to the findings, the group has devised an interactive map at so that residents can investigate contamination levels in their local groundwater.

According to the map, the City of Glen Cove’s water district, with four wells serving a population of about 28,000, and Sea Cliff Operations District, with two wells serving a population of 13,200 in all of Sea Cliff, most of Glen Head, Glenwood Landing and part of Old Brookville, 1,4-dioxane was detected; however, the levels were below the EPA’s cancer risk guideline in both districts.

“The result of our sampling of 1,4-dioxane found one tenth part per billion,” said Michael Colangelo, director of Glen Cove’s water department. “This reading is extremely low and there is absolutely no concern as Glen Cove’s water is completely safe for consumption. Through our consistent testing and monitoring of our water supply we take the utmost care in ensuring our residents have the highest quality water available to them.”

James Neri, an engineer and consultant for the Plainview Water District, said that consumers would have to ingest an impossibly large amount of water before it became detrimental to health.

Levels of the chemical 1,4-dioxane are below the cancer risk in both Glen Cove and Sea Cliff.

“You would have to consume two liters per day for 70 years before you would have a one-in-a-million increased chance of cancer,” said Neri. “They are trying to compel the EPA to move faster, and that’s not necessarily a bad thing, but they are pandering to the side of fear.”

Neri said the study has been around since 2014-15 and since then, water districts throughout Long Island have worked to vet new technologies aimed at stemming the tide of dioxane.

Dioxane gets into the water through products that contain it, including laundry detergent, soap, shampoo and body wash, according to CCE’s report. That report reveals that up to 46 percent of personal-care products contain the chemical, which is not added to consumer goods but rather is an unwanted byproduct of ethoxylation—a process used to reduce skin irritation caused by petroleum-based ingredients. Once in the groundwater and soil, the report stated, it is hard to remove and known as a “legacy” pollution—pollution left behind from past industrial activities.

“While avoiding products in our personal lives is a good first step, we need New York state to act now to prevent further exposure to dioxane through our drinking water,” CCE said.
Senators Kirsten Gillibrand and Chuck Schumer recently announced legislation that would require the EPA to develop a maximum contaminate level for 1,4-dioxane and other hazardous chemicals in public water systems. As 1,4-dioxane is currently unregulated in the Safe Water Drinking Act, this legislation would require the EPA to create safety guidelines and determine legally enforceable standards that apply to water systems.

“We’ve seen very clearly how much damage can happen to our local drinking water supplies when toxic chemicals like PFOA, PFOS, 1,4-dioxane, and perchlorate aren’t monitored by the EPA,” said Gillibrand, a member of the Senate Environment and Public Works Committee. “New Yorkers should be able to drink water without having to worry about whether it’s safe. Anything less than that standard is unacceptable.”

Schumer and Gillibrand called on the EPA to prioritize and accelerate the risk evaluation for 1,4-dioxane. Schumer also urged Saint-Gobain Performance Plastics to work proactively with federal and state environmental officials to define and clean up another contamination in Hoosick Falls.

“With the recent incidents of contaminated drinking water in New York, it’s crystal clear that we need a maximum contaminant level set by the EPA for perfluorinated compounds like PFOA/PFOS, 1,4-dioxane and perchlorate,” said Schumer. “I will use every ounce of my clout to work with my colleagues in the Senate and make sure this common sense public health bill to ensure safe drinking water is passed.”
