< ‘ ' <br />W\TER QUALITY <br />The reason for separating demolition and construction wastes from <br />normal sanitary landfill materials is that the pollution potential of <br />the former is much less. Normally a demolition landfill would receive <br />the following materials: <br />Concrete and bituminous road materials <br />Building demolition debris - wood, bricks, concrete, etc. <br />Trees <br />Waste soil materials <br />The present 16 year old landfill includes unsorted solid wastes. <br />The previous Groundwater Analysis section indicates that some seepage <br />is possible from the landfill to the adjacent marshes. To check on <br />whether there is leaching in significant amounts, water quality samples <br />were taken on April 30, 1973. The location of sampling points is shown <br />in Figure 2. Test results for these water samples from Lake Classen <br />Creek are as follows: <br />Chloride (Cl) mg/1 <br />Nitrate (N) mg/1 <br />Total Solids mg/1 <br />Suspended Solids mg/1 <br />BOD rag/I <br />pH <br />Sample W-1 <br />20 <br />0.41 <br />167 <br />14 <br />1 <br />7.1 <br />Sample W-2 <br />50 <br />0.47 <br />264 <br />8 <br />6 <br />7.1 <br />The tests indicate that there is an Increase in chlorides, total <br />solids, and BOD. However, caution should be taken when assuming that <br />these increases ore directly the result of the existing landfill for <br />the following reasons: <br />1. One sample series based on surface water "grab" samples <br />will not necessarily be representative of average conditions. <br />Other potential pollution sources exist in the area between <br />the sampling points. Among these are the property to the <br />west where some filling has taken place and also Highway <br />12. The highway could be the source for the higher chloride <br />values. <br />2. <br />- 8 -
