John Peter Masterson
John Masterson is the Associate Director for Science Operations in the New York Water Science Center. He completed his B.A. in Geosciences at SUNY Geneseo and M.S. in Geosciences at the University of Missouri-Columbia.
John began his USGS career at the New York Water Science Center on Long Island in 1987, transferred to the New England Water Science Center in Massachusetts in 1990, and has returned to the New York Water Science Center in 2021. He specializes in computer model applications to study groundwater flow dynamics and is an author of numerous USGS technical reports and peer-reviewed articles on groundwater resources in coastal aquifer systems. John is currently serving as the project coordinator for the ongoing NYSDEC-USGS cooperative investigation of groundwater sustainability of the Long Island regional aquifer system.

Water for Long Island: Now and for the future
Do you ever wonder where your water comes from? If you live in Nassau or Suffolk County, the answer is, groundwater. Groundwater is water that started out as precipitation (rain and snow melt) and seeped into the ground. This seepage recharges the freshwater stored underground, in the spaces between the grains of sand and gravel in what are referred to as aquifers. Long Island has three primary aq
