<br /> 10-I8-88 3-10,000 gallon fuel tanks and one 1,000 gallon waste oil tank installed this date.
<br /> 12-16-88 Monitoring wells MW#1 through MW#7 sampled this date. Depth to water was
<br /> approximately 31'-32' BGS. Flow direction was to the north northeast.
<br /> MW#1 and.MW#3 were dry and could not be sampled.
<br /> MW#2 showed TPH as gasoline,BTEX and 1,2-DCA at 1000 ppb,340 ppb,30 ppb,less than
<br /> 10 ppb, 50 ppb and less than 10 ppb, respectively.
<br /> MW#4 showed TPH as gasoline,BTEX and 1,2-DCA at 330 ppb, 1.0 ppb,less than 1.0 ppb,
<br /> Iess than 1.0 ppb, less than 1.0 ppb, and less than 0.1 ppb, respectively.
<br /> MW#5 showed TPH as gasoline,BTEX and 1,2-DCA at less than 500 ppb,less than 5.0 ppb,
<br /> less than 10 ppb, less than 10 ppb, less than 10 ppb, and less than 10 ppb, respectively. A
<br /> duplicate for this well:showed all constituents nondetect except for TPH as gasoline at 100
<br /> ppb.
<br /> MW#6 showed TPH as gasoline, BTEX and 1,2-DCA at 100 ppb,2.7 ppb,Iess than 2.0 ppb,
<br /> 2.0 ppb, 2.0 ppb, and 1.4 ppb, respectively.
<br /> MW#7 showed TPH as gasoline and BTEX at 370 ppb, 1.5 ppb, less than 0.1 ppb, less than
<br /> 0.1 ppb, and 0.5 ppb, respectively.

<br /> MW#1 and MW#3 were dry.
<br /> MW#2 showed TPH as gasoline and BTEX at 1360 ppb, 780 ppb, 23 ppb, 5.5 ppb, and 27
<br /> ppb, respectively.
<br /> MW#4 showed TPH as gasoline and BTEX at less than 500 ppb and less than 0.5 ppb,
<br /> respectively.
<br /> MW#5 showed TPH`as gasoline and BTEX at less than 500 ppb and less than 0.5 ppb,
<br /> respectively.
<br /> MW#6 showed TPH as gasoline and BTEX at 900 ppb, 2.8 ppb, less than 0.5 ppb, 1.3 ppb,
<br /> and 1.4 ppb, respectively.
<br /> MW#7 showed TPH as gasoline and BTEX at less than 500 ppb,3.2 ppb,0.5 ppb,0.7 ppb,
<br /> and 3.4 ppb, respectively.
