New York State is leading the charge for specific drinking water standards for three toxic chemicals: 1,4-dioxane, PFOS, and PFOA.
The state of New York adopted drinking water standards this year for three toxic chemicals. New York adopted a drinking water standard for 1,4-Dioxane, setting the maximum contaminant level of 1 part for every billion for 1,4-Dioxane. The standard is the first in the U.S. New York additionally adopted maximum contaminant levels for perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in the state's drinking water at ten parts for each trillion. It is among the lowest levels in the U.S. for the two contaminants. Under the new guidelines, New York requires testing and monitoring for public water systems.
In a statement, Governor Andrew Cuomo stated, "While the federal government continues to leave emerging contaminants like 1,4-Dioxane, PFOA and PFOS unregulated, New York is leading the way by setting new national standards that help ensure drinking water quality and safeguard New Yorker's health from these chemicals.” He added that the environmental movement was established in this great state. They will keep pushing ahead to protect their most valuable resources for a long time.
The New York Policy Director at the Natural Resources Defense Council, Rich Schrader, indicated that these drinking water standards are among the hardest in the country and an essential move in the battle to protect New Yorkers against this health crisis.
New York’s Drinking Water Program: Facts and Figures
Almost 95 percent of all New Yorkers get water from public water supply systems in New York State. Public water systems in New York extend from New York City, the biggest engineered water system in the country serving more than 9 million individuals, to privately-owned water source companies serving municipalities and schools with their water supply, to small businesses in rural regions serving consumers water from their wells. Altogether, there are more than 9,000 public water systems in New York State.
The number of systems by system type and the population served by each water system is indicated in the table below. The reported value for the total population of more than 21 million served by these systems depends on tallies incorporating water trades between systems, bringing about checks on a similar population on numerous occasions. The overall population figure likewise incorporates customers getting water from transient non-community systems. Other tallies of similar populations and consumers bring about a total value than the state's population.

The number of systems by type of water source and the population served by these systems are given below. Most of the State's population is served by surface water. New York City and Long Island metropolitan areas lead to individuals getting public water in the state. Nine million individuals in the New York City water system get surface water. Most groundwater supplies are concentrated around Nassau and Suffolk counties, representing almost 3 million consumers. The rest of the population getting public water is mainly concentrated in cities, towns, and related suburban zones where public infrastructure has been created throughout the state. A few systems are served by sources named groundwater under the immediate impact of surface water or GUDI. GUDI sources require a similar degree of treatment as surface water sources.

Health Risks of 1,4-dioxane, PFOS, and PFOA

1,4-dioxane is in products that make bubbles, like shampoo, liquid soap, and bubble baths. It infiltrates the skin and is considered a likely human carcinogen by the U.S. Environmental Protection Agency. The National Toxicology Program records it as an animal carcinogen. California's Proposition 65 list of chemicals known or suspected to cause disease or birth defects included it. It isn't recorded on ingredient labels because 1,4-dioxane is made. When basic ingredients like sodium Laureth sulfate, PEG compounds, xynol, ceteareth, and oleth react when mixed.
EWG considers that 1,4-dioxane is around 22 percent of more than 25,000 cosmetic products recorded in its database. Since the U.S. Food and Drug Administration doesn't need to list 1,4-dioxane on product labels, it's impossible to know what a product contains, making it hard for customers to avoid it. One approach to avoid 1,4-dioxane in cosmetic products is to be certified by the U.S. Department of Agriculture's National Organic Program. Research by the Organic Consumers Association found that it doesn't exist in cosmetic products certified by the USDA National Organic Program. A study by EWG found that water supplies for more than 7 million individuals in 27 states have 1,4-dioxane contamination.
PFOS and PFOA are among the chemicals called polyfluoroalkyl substances (PFASs). They are used to make fluoropolymer coatings and fight heat, grease, stains, oil, and water. PFOS and PFOA don't separate in nature, and they can travel through soils, pollute drinking water sources, and develop fish and wildlife. They are found in soil, air, and groundwater over the U.S. Tests charged by EWG discovered PFAS in drinking water in many U.S. cities. Researchers tested water tests from 44 areas in 31 states and the District of Columbia. One example had no detectable PFAS, while two different areas had PFAS underneath the level that separate investigations show is dangerous to individuals.
Centers for Disease Control and Prevention researchers estimated at any rate 12 PFAS in the blood serum of participants 12 years and more. They discovered four PFAS, including PFOS and PFOA, in the serum of practically the entirety of the individuals tested. That is an issue since research recommends that significant levels of PFAS may cause expanded cholesterol levels, changes in liver enzymes, and a greater risk of kidney or testicular cancer.
States Take Measure
Almost 50% of all states are attempting to compose their direction, regulations, or legislation to address drinking water contamination from PFAS instead of an absence of enforceable government principles.
In July, Michigan passed a law setting the country's strictest level for PFOA at eight parts for every trillion. The legislation sets the PFOS level at 16 parts for each trillion.
The government has set a lifetime health advisory level for the two chemicals at 70 parts for each trillion.
The 3M Co. and DuPont were the first organizations to create and develop PFAS, dating back to the 1940s. Companies like Wolverine World Wide, Inc. have used chemical substances made with the specific PFAS that 3M, DuPont, and Chemours, a Dupont side project. Also, W. L. Gore and Associates, Inc. makes many products, including semiconductors, sticky notes, shoes, and firefighting foam.
However, some chemicals don't separate effectively and stay in the environment and human bodies for quite a while, winning them the name "forever chemicals.” They have been connected to specific cancers, hormone disruption, and other ailments, as indicated by the U.S. Environmental Protection Agency.
The state health department has worked with other state offices to help examine, remediate, and fund water systems that test over the limits, fully expecting the adopted levels.
The state 2018 declared $200 million in grants to assist communities with tending to PFOA, PFOS, and 1,4-dioxane in drinking water supplies, as per the health department. The grants help limit the economic effect of remediation on ratepayers.
Too Much, or Not Much Enough?

An industry group called the American Chemistry Council said New York's new limit points are much stricter than expected to protect individuals.
The council stated that the EPA built a health advisory level of 70 parts for every trillion PFOA and PFAS, "well over" the new state limit. It said the animal liver impacts that are the reason for the PFOA limit in New York "don't seem pertinent to human exposure."
As far as possible, 1,4-dioxane is 50 times lower than the suggestion given by Health Canada and the World Health Organization, as indicated by the council.
As the council stated, it will continue to work on behalf of its members to support policies that protect public well-being and depend on the best accessible science.
Environmental supporters commended the long-anticipated action, yet some said the state should have gone further.
Rob Hayes, the clean water associate at Environmental Advocates NY, said, “These new drinking water protections are the direct result of tireless advocacy by community members who have these chemicals in their blood.” He added the science is precise: to protect people from cancer and other health risks, New York must eliminate all PFAS from drinking water.
The Natural Resources Defense Council likewise called for additional action, citing many poisonous "forever" chemicals as dangerous to public health. Encouraging the general public to use a water filter like Berkey Water Filter would also be beneficial.
