Development of 19 monitoring wells. The 7th sampling of existing supply wells (pursuant to Administrative Order No. II - CERCLA 00401 and RCRA - 90 - UST - 9003 - 0401). Allow monitoring wells to stabilize. Collect synoptic round of water-levels at all 19 monitoring wells. First ground-water sampling of all 19 monitoring wells. Long—term ground—water level recording to check for possible influence from pumping wells. Review long—term data. Coordinate/prepare for pumping test. Set-up water-level recorders for pre-pumping trend. 4-hour step-test at MW—9 or MW—10; record recovery. Set-up recorder for pre—pumping trend for November 2 test Start 24-hour pump test at MW-9 or MW—10; pumping rate to be determined from the results of October 30 step-test. End test; record recovery; data analysis. 4-hour step-test at MW- 10D; record recovery. Set—up recorder for pre-pumping trend for November 9 pump test.
