Articles Regarding 1,4-dioxane
In a recent edition of Newsday there are two articles about contaminants in public water
supplies on Long Island. They stem from the results of the EPA's third Unregulated
Contaminant Monitoring Rule ("UCMR") that was released in August 2016. Every five
years the EPA is required to designate a list of contaminants which are not presently
regulated. This means that there are no national safe drinking water standards
established for these contaminants. The EPA studies the results and determines if
any of the contaminants pose a health risk and should be regulated.
One article focused mainly on one contaminant, 1,4-dioxane which is a solvent used in
textile processing, printing processes and detergent preparations. Although the EPA
has not set a standard for 1,4-dioxane, New York State has established a standard of
50 parts per billion for any unregulated organic chemical, including 1,4-dioxane. The
Water Authority's highest detection of 1,4-dioxane is 12 parts per billion at one
location, well below the standard. The remainder of the results range for no detection
to 0.84 parts per billion.
At present there is no treatment method for the removal of 1,4-dioxane from the water
supply, however Suffolk County Water Authority is performing a large-scale pilot study
aimed at removing 1,4-dioxane. Construction of the pilot treatment system is
scheduled to be completed by April of this year. Suffolk County must collect data for a
year before it can present their result to the State for approval of the treatment
As with any regulated contaminant if the water from any of Long Island's public water
supply wells exceeds the standards, the wells must be taken out of service until
treatment is installed to remove the contaminants from the water. At present the
Water Authority uses air-stripping and granular activated carbon facilities to remove
volatile organic compounds ("VOC") from the water. Construction is underway for two
new air-stripping facilities to treat four wells that have been out of service due to VOC
The Water Authority customers can rest assured that the public water that flows from
their faucets is one of the most highly regulated supplies in the United States and is
safe to drink.

Water Authority of Western Nassau County Board Approves Water Rates Effective June 1, 2016
New Hyde Park, NY — At its May 23rd public rate meeting, the Board of Directors of the Water Authority of Western Nassau County (Water Authority) approved an overall 9.4% increase in water rates. Residential customers will receive a 4.1% increase while commercial customers will receive an increase based on the size of their meter. Public fire hydrant rates will remain unchanged from the current annual charge of $936.
The 9.4% increase in rates is a result of the Water Authority’s increased costs related to debt service costs required to fund the Water Authority’s capital plan which includes critical projects related to wellhead treatment or iron removal. The most significant project is the design and construction of two VOC (“Volatile Organic Compound”) treatment facilities required to treat the water provided by four wells, all located in Elmont, which are currently out of service due to the VOC levels. These wells are responsible for providing approximately 7.5 million gallons of water capacity to our system on a daily basis and are critical to the western portion of our service territory. Water supplied by the four wells is stored in the 5-million gallon storage tank located across from Belmont Park.
The Board of Directors and Water Authority staff completed its review of the comprehensive rate
study conducted by D&B Engineers and Architects, P.C. (D&B). D&B was hired to independently assess and evaluate the Water Authority’s existing water rate structure as distributed to its four customer classes while ensuring adequate funding of all water operations as well as all capital and debt service costs.
The quarterly bill for the minimum use customer will increase from $41.51 to $44.38. Average annual
residential charges (based on average usage of 104,600 gallons per year) will increase from $440 to $466. The average annual commercial charges (based on average usage of 482,300 gallons per year) will increase from $1,832 to $2,293.
