Mr. Shawn Napier, P.E. July 18, 2007 Page 3 , Task 3 -1=acility Well Inventory WBC will conduct an inventory of existing facility monitor wells and piezameters as required by the TCEQ. According to TCEQ files, there may be 26 facility wells on or adjacent to the landfill. Based an WBC's review of the case files, there maybe more wells at the site. For all located facility wells, each well's coordinates, depth, water level, well condition, and repair/plugging recommendations will be recorded. This task assumes the City will provide a surveyor with a GPS unit to accompany WBC's inventory technician for about two days and record well coordinates. The City's surveyor costs are not included in this proposal. Consistent with previous City proposal requests, the City's surveyor will invoice the City directly, Task 4 -Groundwater Sampling and Analyses Events Ta determine if groundwater contamination issues persist, two consecutive quarterly groundwater.sampling-events will~be-completed in the five landfill monitoring~~vells and 14 piezameters requested by the TCEQ in ,1898. WBC will provide an experienced sampler and all necessary sampling equipment to complete the field portion of this task., Immediately prior to purging and sampling, water levels and methane gas concentrations will be measured. in l 9 wells and piezometers at-the site. The piezometers will be purged and sampled in accordance with standard practices and consistent with recent events. Groundwater samples. wild be collected from monitoring wells MW-1, MW-2, MW-3, MW-~, MW-5, and piezozneters MW-4A, MW-SA, P-l, P-2, P-3, P-4, P-5, P-6, P-9, P- 10A, P-11, P-12, P-13, and P-l~.
