~ . ' <br /> ' <br /> t <br /> In order to determine if there has been any impact on the <br /> ground water from the oil spill at this site, and to aid in <br /> determination of the magnitude of the potential problem, should <br /> one be discovered to exist, the following is recommended: � <br /> ' 1 . Falling head permeability tests should be conducted in each <br /> of the three monitoring wells to determine a field coefficient of <br /> permeability for the soils at the site. <br /> 2. An additional monitoring well should be located in the field, i <br /> the location of which should consider the maximum plausible area <br /> that might be contaminated, based on the average of the results <br /> of the field permeability tests and on the ground water flow ' <br /> direction determined from well measurements prior to the test. � <br /> 3. The monitoring be sampled to determine if any i <br /> contamination from the spill has impacted th water. <br /> �� ' -- <br /> ��, w~°«~4~�-�� °~�--- ^ � � -�- dations <br /> The above represents my best pro+ess�o'/a1 re cux:x�'/ <br /> with respect to determining the extent of possible ground water <br /> contamination at this site. The recommendations are made based <br /> on the data at hand, and are based on geplogic intuition. <br /> Additional data gained through further work at the site may show <br /> that basic assumptions are different than presently envisioned. <br /> Such a situation could be cause for a change in conclusions or ^ <br /> re,ommendations in this report. <br /> eD <br /> � 0 Sincerely, <br /> oe <br /> HENKLE, JR.
