Due to the extended and heavy rainfall experienced in the area over the past several months the local
groundwater level has risen approximately 5 feet since the system start-up in March. The increase
in groundwater levels has reduced the overall capacity of the system to re-inject and the average
pumping rates of the wells have been decreased. The pumping rates will be closely monitored and
adjusted based on the local groundwater levels.

SVCW-1: The downwell pump and packer assembly were removed and repaired on 28-30 May
2003. The well was restarted on 30 May 2003.
DVCW-4: The injection potential of the formation was investigated by taking the well off-line for
several hours and injecting water into the formation over a range of pressures. Approximately 40
psi was necessary to inject water at a rate of IO gpm. Subsequent to the test. the well was returned
on-line and the injection capacity was improved. The injection capacity was consistent with the
extraction rate of approximately 3 gpm.

Issue: The downwell pump malfunctioned and was removed. The pump was tested and found to be
defective and will be replaced under warr_anty.
Resolution: Replacement is scheduled for 12 June 2003.
DVCW-4:
~ The well vault was flooded due to a mechanical malfunction and/or surface water runoff from
a rainstorm. A resident noticed water above the top of the vault and flowing on to the road during a
rainstorm on 02 June 2003. The resident contacted EA. via McCall Brothers Construction. and the
well was turned off and pumped out. Upon removing the water from the vault. the well was
restaned.
Resolution: EA will install float switches in each well vault to shut off the well pump(s). and send
an alarm. in the event of the accumulation of measurable water in the vault(s). The switches and
additional controls are scheduled to be installed by the week of 23 June 2003.

water was observed leaking into the bottom of the vault box and into the casing above the
upper packer. During attempts to identify and repair the leakages, the upper and lower
packer assemblies were separated. The lower packer assembly remains in the well and the
system is not currently operational. Replacement and repair parts have been ordered and the
pump and packer assemblies will be removed and repaired as soon as the parts are received.
SVCW-1 is expected to be back on-line during the week of26 May 2003.
DVCW-4: The extraction rate continues to be closely monitored and regularly adjusted to
correlate with the changes in injection capacity. The injection capacity has been less than
anticipated. During the week of 26 May 2003 the injection potential of the formation will

The air-stripping unit was not achieving the design removal efficiency. Representatives
from EA and the manufacturer met onsite on 22 and 23 April 2003 to investigate and
troubleshoot the system. The source of the problem was determined to be insufficient flow
through the air-stripping unit. The resolution was to reconfigure the vapor system piping
and replac.e the two existing carbon units with a larger unit capable of handling a higher
flow rate.
The equipment change-out and piping reconfiguration will be completed by 30 April 2003.
The system will be restarted and operated for five days on an interim basis to verify proper
operation of the unit. During this five-day period influent and effluent samples will be
collected twice per day. One sample from each of the first three days will be analyzed
• within a 24-hour turn around time (TAT) period. The remaining samples will be analyzed
within a normal IO-day TAT. After the five-day interim operation period, and verification
of proper system operation, EA will begin the fourth and final week of the 30-day
performance-testing period. Upon conclusion of the fourth week of performance testing
EA will initiate the 335-day annual operation and maintenance period.

The 7--day performance testing period was initiated on 3/20/07 at 1600 hours. The system operated
continuously over the 7-day, 168 hour period except for two planned shutdowns of approximately
IO minutes each for system programming.
The following technical issues were observed and addressed during the past 7-day period:
SVCW-1: The downwell pump and packer assembly was removed and the problems were repaired
on 27 March 2003. Subsequent to re-installation of the downwell assembly the well was restarted
and water was observed leaking from the high voltage wire casing and into the pump switch box in
the well vault. The downwell pump and packer assembly was removed and inspected on 02 April
2003. The groundwater pump and level transducer were not working properly and will be
replaced. A new pump and transducer were ordered. SVCW-1 is expected to be fully operational
during the week of 14 April 2003.
DVCW-4: The extraction rate continues to be closely monitored and regularly adjusted to correlate
with the changes in injection capacity. The injection capacity has been decreasing steadily. The
injection rate may be limited by the re-injection pump capacity.

continuously over the 7-day, 168 hour period except for two planned shutdowns of approximately
IO minutes each for system programming.
The following technical issues were observed and addressed during the 7-day period:
SVCW-1 was not operated continuously due a problem with silt accumulation in the well and the
integrity of the groundwater extraction line in the well. The downwell pump and packer assembly
was removed and the problems were repaired on 3/27/03. Subsequent to re-installation of the
downwell assembly the well was restarted and water was observed leaking from the high voltage
wire casing and into the pump switch box in the well vault. The downwell pump and packer
assembly is scheduled to be removed and inspected/repaired during the week of 31 March 2003.
SVCW-1 is expected to be fully operational during the week of 31 March 2003.
SVCW-3 was observed to have water accumulating in the casing above the upper packer. The well
was shut down and accumulated water was intermittently drained from the casing several times
during the test period. The downwell pump and packer assembly is scheduled to be removed and
inspected/repaired during the week of 31 March 2003. SVCW-3 is expected to be fully operational
during the week of 31 March 2003.
DVCW-4 was observed to have a variable capacity for injection. The injection piping and
downwell assemblies were inspected for mechanical integrity. No blockages or leaks were
observed. The extraction rate will be closely monitored and regularly adjusted to correlate with the
changes in injection capacity.
