Permit No. 13763R - Ary -This well is the upstream-most
well identified that was completed in the Chandler Creek alluvium. This
well was coipleted in 1952 to a depth of 20 feet and had a reported
production rate of 500 gpm. However, Northfield's consultants visited
the well in 2006 and observed that the well is not in use and is in a
state of disrepair. In addition, Jeanette Bryan, well inspector with the
DWR completed a recent site visit to the well and reported that it is
dry, which suggests that the alluvium is not saturated at this location.
Permit No. 15899 - Ary -This well is reportedly located
downstrearri of'the permit boundary and has reported depth of 50 feet
and a reported static water level of 10 feet. There is no geologic log in
the well record, but based on the well depth, the possibility exists that
the well is completed in the Chandler Creek alluvium.
Permit No. 79354-A -Brown -This well is located
downstrearri of the Northfield property boundary. The well log indicates
that the well penetrated the sand and gravel to a depth of 30 feet;
water was encountered at 30 feet and the static water level is at 25
feet. This indicates that there may be 5 feet of saturated alluvium at
this location, but the well is dually completed in the alluvium and
bedrock, arnd as a result, it is not clear if that water level is
representative of the alluvium or bedrock.
Permiit No. 3759-F -Town of Williamsburg -This well is
located downstream of the permit boundary and has a reported depth
of 40 feet and a pumping rate of 200 gpm. The depth and pumping
rate suggest: that the well produces from an alluvial source. There is no
geologic log in the well record, and as a result, the sediments that the
well producE~s from could not be confirmed. On August 30, 2007, a
Town of Williamsburg representative stated the Town of Florence
required the pump be removed when Florence became the water
supply for VI~-illiamsburg. The well can only be used in case of a fire
emergency.
Wells could snot be identified that clearly show that there is production
from an alluvial source, but the records referenced above indicate that
there may be an alluvial aquifer present in localized portions of the
Chandler Creek alluvium, although it is believed that saturated aquifer
conditions are not present extensively throughout the Chandler Creek
channel. ThE~re may be additional water supply wells completed in the
alluvial aquil=er in addition to these referenced above. For example,
wells were identified with no completion details, and those wells were
not listed above.
