Water Supply Improvement
Wellhead Treatment for VOC Removal
Phase 1 - Stations 15A & 15C/E
Anticipated Completion Date: Fall 2017
As part of our commitment to providing a safe and reliable supply of high quality drinking water for our customers, we are bringing select wells back into service upon installation of wellhead treatment for the removal of volatile organic compounds (VOCs) commonly found in Long Island's groundwater. By increasing the reliability and availability of drinking water supply in our service area, we will be better able to serve our customers and have more resources ro respond to emergency situations.
Station Number 15A: The existing building will be replacedwith a new energy efficient building and setup for off-site future wellhead treatment.
Station Number 15 C/E: Construction of a new energy efficient treatment building, rehabilitation of the existing building, and installation of a new emergency standby generator.
The Water Authority would like to remind homeowners and businesses of the importance of keeping fire hydrants free of ice and snow so firefighters can connect their equipment without delay in the event of an emergency.
In an emergency, every second matters. Fire hydrants that are blocked,
concealed or difficult to access due to snow or ice can impede emergency
Fire trucks carry a finite amount of water, so one of responders’ first
tasks upon arriving at a fire is to locate a water supply from the
nearest hydrant. Hydrants covered in snow can be difficult to locate,
and uncovering them can waste valuable time needed during a fire fight.
Keeping them clear can mean easier access to water and more time doing
what really matters — fighting the fire.
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.
