Mr. Daniel A. Comeau <br />September 2!~, ]gF~~, <br />Page lwelv(, <br /> <br />Moni to_r_!n_g- Well Saint/Ii_!9_9 <br /> <br />34. <br /> <br />P_~Q~Qes 17-]8. Groundwater Sampling Event No. ] was conducted on July 22-26, <br />On AuguSt 28-30, the second water quality sampling event was conducted. <br />Samples from both sampling events were analyzed using Method 624. <br />Additionally, those wells which showed evidence of measurable quantities <br />of water quality parameters were analyzed by Method 465 during the second <br />sampling event. <br /> <br />Non-volatile parameter testing is being conducted during each water <br />quality sampling event. Typical parameters associated with landfills, <br />such as those parameters listed on Page A6 of "Procedures for Groundwater <br />Monitoring: Minnesota Pollution Control Agency Guidlines" April 1985 have <br />been included. Additional parameters required under provisions of the <br />Anoka County operational permit have also been included. This data is <br />being compiled and evaluated as part of the on-going internal analysis <br />of available data. <br /> <br />The QA/QC Plan for Water Sampling and Analysis will be updated and <br />provided to MPCA in October (see Response No. 39). <br /> <br />Five surface water locations are monitored for water quality parameters. <br />The surface water locations are SW-1, SW-2, SW-3A, SW-4, and SW-5 <br />(see Table 6 of the Evaluation Report). Location SW-3 is located in the <br />same wetland as SW-3A. Location SW-3 was used as a water level <br />measurement point because of its accessibility and ability to monitor <br />potential fluctuations in water level. SW-3A is used as a water quality <br />sampling point only and was designated by MPCA staff while on-site. <br /> <br />All on-site groundwater monitoring wells have been sampled during Sampling <br />Event No. 1 (July 22-26) and Sampling Event No. 2 (August 28-30). It is <br />possible that some of the groundwater monitoring wells may be deleted from <br />the proposed Water Sampling Event No. 3. This potential action will be <br />determined after results from Water Sampling Event No. 2 have been <br />received and evaluated. It is anticipated that discussions will take <br />place with MPCA staff and that a proposed modification to the monitoring <br />well sampling program will be documented and submitted to the MPCA before <br />Sampling Event No. 3 is instituted. <br /> <br />Records Search <br /> <br />35. <br /> <br />~ages 18-19. Preliminary records search information is included in the <br />Evaluation Report. An on-going records search is currently being <br />conducted. The records search has involved public documents (City of <br />Anoka, Anoka County, City of Ramsey, Metropolitan Council, and MPCA) and <br /> <br /> <br />
