WaterTraq gives users an in-depth look at water quality in the aquifer from across Long Island.
The Long Island Commission for Aquifer Protection launched a major update to WaterTraq, its groundwater quality mapping and data system, which has been collecting and making publicly available water quality data from most Long Island water suppliers for over a decade. With the new enhancements, users can now not only search for the presence of chemical compounds but also view long-term trends in concentrations over the past ten years.
WaterTraq, a GIS-based platform developed in partnership with the Suffolk County Water Authority, has long served as a central resource for regulators, water professionals and the public to access raw and treated water quality data across Long Island. Updated functionality gives users the ability to chart how levels of contaminants have changed over time in specific sections of Long Island.
“This update transforms WaterTraq from a snapshot tool into a dynamic resource that tells the full story of our groundwater’s health,” said Jeff Szabo, Chairman of LICAP and Chief Executive Officer of the Suffolk County Water Authority. “Users can see whether compound concentrations have increased, decreased or remained stable—giving them the information that supports smarter decisions, deeper research and stronger protections for Long Island’s water supply.”
LICAP Vice Chair and Superintendent of the Hicksville Water District Paul Granger, P.E. added “The transparency and ability to proactively track groundwater quality trends is invaluable for water suppliers. WaterTraq is a vital public health protection tool for wellhead treatment planning.”
By layering maps with historical water quality data, users can overlay contaminant concentrations with geographic features like aquifer boundaries, well locations and topography. The tool serves both technical users and residents seeking clearer access to data.
