• <br />October 2000 <br />-34- <br />003-2191 <br />The potential for impact to the groundwater is also considered slight because of the <br />following: <br />• It is unlikely that sufficient leachate will develop in the fill to cause a release <br />because of the nature of the waste (construction and demolition debris) to be <br />placed and limited annual precipitation in the area; <br />• The landfill will have a recompactedclay liner; <br />• The depth to groundwater below the fill will be between 60 and 100 feet; <br />• The uppermost groundwater system is not highly permeable or laterally <br />extensive; and <br />• Subsurface bedrock materials between the base of fill and top of groundwater <br />consists of relatively thick claystone sequences which would be relatively <br />impermeable. <br />• <br />In any event, if leachate were to be release from the site, the groundwater monitoring <br />system will detect the leachate migration long before it impacts any downgradient <br />receptor. Additionally, the "tight" bedrock materials would probably retazd the leachate <br />movement and act as a buffering system to any organic and inorganic acids. <br />3.2.2(G) The Existing Quality of Groundwater Beneath the Proposed Facility <br />According to Robson (1987), water in the Dawson and Denver aquifers is generally of <br />good quality and is dominated by calcium and bicarbonate ions except near some <br />mazgins of the aquifers where water types can be classified as sodium bicazbaonate or <br />sodium sulfate. Dissolved solids concentrations in both aquifers range from less than <br />100 milligrams per liter (mg/L) in the south-central part to more than 1,000 mg/L to the <br />north. Typical ion concentrations for water in the Dawson and Denver aquifers are as <br />follows. <br />`~ <br />VOLLR191RI91SLIiePmniil000d9c Sedalia Recycling Center and Depository <br />
