April 21 , 1997
The purpose of this correspondence is to present the results of the aquifer testing
conducted on ten groundwater monitoring wells at the Warren County PCB Landfill in
Warren County, North Carolina. The aquifer testing was performed on April 15 and 16,
1997, and consisted of rising and falling head tests ( slug tests) on monitoring wells MW-
3 A, MW-4A, MW-5 , MW-6, MW-7, MW-8, MW-9, MW-lOS, MW-lOD, and MW-12.
The purpose of the testing was to assess the values of horizontal hydraulic conductivity
(K) at various locations within the water table aquifer at the site.
FIELD WORK SUMMARY :
Field work began on April 15 , 1997. Upon arrival, all on-site monitoring wells
were opened. Water levels were measured approximately 10 minutes after the caps had
been removed to allow pressures to stabilize. Water levels were measured from a datum
point marked on the top of the stainless steel well casing.
A 5.5-foot long stainless steel slug was used to displace water inside the wells. A
Teflon coated stainless steel leader wire was used to attach the slug to nylon rope in order
to prevent the nylon rope from being introduced into the wells. A 20 pounds per square
· inch (psi) stainless steel pressure transducer equipped with Teflon cable was used to
measure water level fluctuations during each test.

Aquifer Slug Testing Report
The stainless steel slug, water level indicator, and the pressure transducer . were
decontaminated before use in each well and prior to leaving the site. The decontamination
procedure consisted of a de-ionized water rinse followed by an Alconox wash, another de-
ionized water rinse, a pesticide grade isopropanol rinse, a de-ionized water rinse, and a
final rinse with organic-free purified water.
An electronic data logger (In-Situ SE 1 000C) was used to record the water levels
during the testing. Frequent checks of the electronic data were performed by verifying the
readings with a water level probe (Solinst 101-B).
The first portion of the test was a falling head test that measured the rate water
levels fell back to static after the injection of the decontaminated stainless steel slug.
Water level data from the transducer was recorded at logarithmic time intervals by the
data logger. The falling head test was terminated after water levels had recovered to
within 95% of their pre-test level.
A rising head test was performed on each well after the falling head test was
completed. The rising head test was conducted by initiating a new logarithmic recording
step on the data logger simultaneously with the removal of the slug. The data was
checked with hand held readings, and the test was terminated after water levels had
recovered to within 95% of the pre-test level.
DISCUSSION:
The slug test data was analyzed using the Bouwer and Rice and Hvorslev methods.
The Bouwer and Rice method accounts for partial penetration effects and changing
aquifer thickness (water table conditions). An aquifer thickness of 50 feet was assumed
for the water table aquifer, except for MW-10D, where an aquifer thickness of 7 5 feet was
assumed. A packing porosity of 25 percent for the well filter pack was assumed.
The results of the slug test data analyses are summarized on the following tables:
