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 a
mixed-use redevelopment will include 2,800 residential units
and 2 million square feet of commercial and light industrial space;
anticipated water demands include
potable water demand at full buildout = 1.4 MGD, and
irrigation 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 from
39 test wells,
16 drive points (11 in wetlands, 5 in stream), and
3 stream flow monitoring points. A groundwater model included the following:
Transient Visual
MODFLOW model;
modeling period was
4,500 hours, or 180
days of continuous
pumping;
no surface recharge
to simulate worst-case
pumping conditions; and,
model calibrated to
within 0.72 feet of
observed water levels. Conclusions:
well is not suitable for potable water supply,
limited recharge and
poor water quality;
pumping impacts included
stream - minimal,
wetlands - some drawdown near well,
clean-up sites - no impact, and
well is suitable for irrigation use.
