<br /> MW#6, and MW#7 were dry and could not be sampled.
<br /> MW#2 showed TPHi as gasoline and BTEX at 80,000 ppb, 6,500 ppb, 2,800 ppb, 280 ppb,
<br /> and 2,000 ppb, respectively.
<br /> MW#4 showed TPH as gasoline and BTEX at less than 500 ppb,98 ppb, 0.8 ppb, Iess than
<br /> 0.5 ppb, and 10 ppb,respectively.
<br /> MW#5 showed TPH as gasoline and BTEX at less than 500 ppb, 1.0 ppb,09 ppb, less than
<br /> 0.5 ppb, and 1.0 ppb, respectively.
<br /> 09-08-89 Only MW#2 was sampled this date and showed TPH as gasoline and BTEX at 8,000 ppb,
<br /> 8,100 ppb, 2,300 ppb, 440 ppb, and 2,200 ppb, respectively.
<br /> 10-05-89 Monitoring, wells MW#1 through MW#7 sampled this date. Depth ;to water was
<br /> approximately 34'BGS. Flow direction was to the north northeast. MW#1,MW#3,MW#4,
<br /> MW#6, and MW#7 were all dry and could not be sampled.
<br /> MW#2 showed TPH as gasoline and BTEX at 58,000 ppb, 13,000 ppb, 6,500 ppb, 1,200 ppb,
<br /> and 6,800 ppb, respectively.
<br /> MW#5 showed TPH as gasoline and BTEX at less than 250 ppb and less than 0.5 ppb,
<br /> respectively.
<br /> 1990
<br /> 03-00-90 Monitoring wells MW#2A, MW#4A, MW#5A, MW#8, MW#9, MW#10 and MW#11
<br /> drilled this month and next month.
<br /> MW#2A was sampled at 30' and 35'BGS. All constituents showed nondetect at appropriate
<br /> detection limits at both depths except for benzene at 0.07 ppm at 35' BGS.
<br /> MW#4A was sampled at 30' and 35' BGS and all constituents showed nondetect at both
<br /> depths except for toluene at 0.02 at 30' BGS.
<br /> MW#5A was sampled at 35' BGS and showed nondetect for all constituents at the
<br /> appropriate detection limits.
<br /> MW#8 was sampled at 30' and 35' BGS and showed nondetect for all constituents at both
<br /> depths except for xylene at 0.02 ppm at 35' BGS.
<br /> MW#9, MW#10, and MW#11 were all sampled at 35' BGS and all showed nondetect for
<br /> all constituents.
<br /> 04-11-90 Mg
<br /> onitorin well MW#2,MW#2A,MW#4,MW#5,MW#5A,MW#8,MW#9,MW#10 and
<br /> MW#11 were sampled this date. Depth to water measurements were not taken at this
<br /> sampling event. TPH as gasoline was not run on the water samples from these wells.
<br /> MW#2 showed BTEX at 2.0 ppb, less than 0.3 ppb, less than 0.3 ppb, and 2.0 ppb,
<br /> respectively.
