Ground-water levels and potentiometric surfaces, Naval Air Warfare Center, West Trenton, New Jersey, 2000

Water levels were measured in wells at the decommissioned Naval Air Warfare Center in West Trenton, N.J., during 2000. Water-level hydro­graphs prepared from data collected at seven obser­vation wells on the base show changes caused by seasonal and daily climate conditions and by the pumping of contaminated water from recovery wells. Stressed and unstressed potentiometric sur­faces for 2000 are similar in shape to those during 1995–99, but are not as deep. The greatest differ­ences between the potentiometric surfaces in 2000 and those in 1995–99 were caused by turning off sump pumps in NAWC buildings when the base was closed.
