groundwater monitoring. The hydrogeologic investigation is expected to take place during Fiscal Year
2015/16; this investigation is not considered as part of this scope of work.
Concurrently, CH2M's proposed scope of work in this proposal is aligned with the City's goal to meet
regulatory guidelines by repairing sections of final cover damaged by erosion during the Tong -term care
period of the City's Landfill; to investigate landfill gas generation and potential for migration; and to
research a discontinued synthetic liner material used during closure, determine appropriate patching
techniques, and develop specifications and details to document repair procedures. The professional
