Purging of the wells was performed using a decontaminated Grundfos Rediflo II electric
pump with prepackaged, disposable poly tubing. A minimum of three (3) well volumes
were evacuated from all the other wells at each location.
Monitoring-wells designated as MW-201, MW-202, MW-203 and MW-204 were not
sampled during this sampling event. Monitoring-wells designated as MW-102, MW-
1 08, and MW-11 0 were dry and no samples were taken.
Field parameters, including pH, temperature and conductivity were monitored during the
purging process. Parameters were measured on intervals of 5 to 10 gallons purged.
Each well appeared to stabilize during purging.
Field measurements, at the time of sampling are summarized below in Table 2:
