Biography
John Masterson is a senior hydrologist at the USGS New England Water Science Center in Massachusetts. He completed his B.A. in Geosciences at SUNY Geneseo and M.S. in Geosciences at the University of Missouri-Columbia. John began his career at the USGS Syosset, N.Y. office in 1987 and worked there for 3 years before transferring to the Northborough, Massachusetts office in 1990. 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. Recently, John completed a regional groundwater availability assessment of the Northern Atlantic Coastal Plain aquifer system from Long Island to North Carolina. 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 (Long Island Groundwater Sustainability Study).

Hydrogeology and Simulated Ground-Water Flow in the Salt Pond Region of Southern Rhode Island
The Salt Pond region of southern Rhode Island extends from Westerly to Narragansett Bay and forms the natural boundary between the Atlantic Ocean and the shallow, highly permeable freshwater aquifer of the South Coastal Basin. Large inputs of fresh ground water coupled with the low flushing rates to the open ocean make the salt ponds particularly...

Effects of sea-level rise on ground water flow in a coastal aquifer system
The effects of sea-level rise on the depth to the fresh water/salt water interface were simulated by using a density-dependent, three-dimensional numerical ground water flow model for a simplified hypothetical fresh water lens that is similar to shallow, coastal aquifers found along the Atlantic coast of the United States. Simulations of sea-level...

Effects of aquifer travel time on nitrogen transport to a coastal embayment
Effects of aquifer travel time on nitrogen reaction and loading to Popponesset Bay, a eutrophic coastal embayment on western Cape Cod, Massachusetts, are evaluated through hydrologic analysis of flow and transport. Approximately 10% of the total nitrogen load to the embayment is intercepted by fresh water ponds and delivered to the coast by...

Transient Analysis of the Source of Water to Wells: Cape Cod, Massachusetts
A transient flow modeling analysis for potential public-supply wells on western Cape Cod, Massachusetts, demonstrates the difference between transient and steady-state recharge areas can have important implications for wellhead protection. An example of a single pumping well illustrates that commonly, used steady-state time-related capture areas...

Simulated pond-aquifer interactions under natural and stressed conditions near Snake Pond, Cape Cod, Massachusetts
A numerical model was used to simulate pond-aquifer interactions under natural and stressed conditions near Snake Pond, Cape Cod, Massachusetts. Simulation results show that pond-bottom hydraulic conductivity, which represents the degree of hydraulic connection between the pond and the aquifer, is an important control on these interactions. As...

Delineation of groundwater recharge areas, western Cape Cod, Massachusetts
The unconfined sand-and-gravel aquifer in western Cape Cod, Massachusetts, which is the sole source of water supply for the communities in the area, is recharged primarily from precipitation. The rate of recharge from precipitation is estimated to be about 26 inches per year (in/yr), or about 60 percent of the precipitation rate. This recharge...
