Full Description

This poster presentation provides a brief project overview that includes the following: South Weymouth Naval Air Station, 1,450 acre base closed in 1997 and amixed-use redevelopment will include 2,800 residential unitsand 2 million square feet of commercial and light industrial space;anticipated water demands includepotable water demand at full buildout = 1.4 MGD, andirrigation water demand for golf course = 0.3 to 0.45 MGD. A Pumping test included the following: well was pumped for six days;well was shut down without stabilization;data sources during test were from39 test wells,16 drive points (11 in wetlands, 5 in stream), and3 stream flow monitoring points. A groundwater model included the following:Transient VisualMODFLOW model;modeling period was4,500 hours, or 180days of continuouspumping;no surface rechargeto simulate worst-casepumping conditions; and,model calibrated towithin 0.72 feet ofobserved water levels. Conclusions:well is not suitable for potable water supply,limited recharge andpoor water quality;pumping impacts included stream - minimal,wetlands - some drawdown near well,clean-up sites - no impact, andwell is suitable for irrigation use.
