8 ANNUAL DATA FOR MONITORING WELLS Introduction Four monitoring wells, QK- through QK-4, are located on the perimeter of the Gloria Alitto Majewski Chicagoland Underflow Plan Reservoir. Well QK- is positioned at the northwest comer of the reservoir, with QK-2, -3, and -4 at the northeast, southeast, and southwest comers, respectively (Figure ). In addition, there are nine privately owned water supply wells, WX through W9X, which are located within,000 ft of the reservoir. The four monitoring wells are sampled quarterly and for at least six consecutive weeks following each reservoir fill event in which the reservoir is used to store combined sewer flow from the Tunnel and Reservoir Plan system (Illinois Environmental Protection Agency [IEP A] memorandum dated October 4, 997). Fill-event samples may substitute for quarterly samples, depending on the occurrence of fill events. Groundwater elevations are also measured during each sampling event. There are no observation wells associated with this site. There were three fill events at this site during the weeks of2/7/6 through 8/30/ 6. Based on IEP A requirements, the wells should be sampled for at least six consecutive weeks following a fill event. As a result, Wells QK- through -4 were generally sampled for six consecutive weeks (2/7-3/22/6), and again for consecutive weeks (6/24-8/30/6), following two consecutive. fill events. However, Well QK-3 was sampled for a total of only weeks following all events due to heavy construction traffic and poor road conditions in the vicinity of this well. One additional quarterly sample was collected at each well in December. Summary of Data Monitoring Wells. The analytical data for groundwater sampled during 206 from monitoring wells QK- through -4 are presented in Table. Physical characteristics, such as elevation, groundwater temperature, and estimated time of recharge for each well between initial pumpdown and sampling are also included. Table 2 lists the overall descriptive statistics for the groundwater data for these wells during 206. Following repairs and flushing of these wells in 204, and decontamination in 204 and 205, the FC population in Well QK- was finally controlled. Throughout 206, FC in all wells at this site was undetectable ( CFU/00 ml), except in QK-3 during three sampling events of summer 206 (Table ).
