AA Waste owns the Buckeye landfill that overlies the TrueBlue aquifer (see Figure 1). The TrueBlue aquifer is a precious resource to some local community activists. In addition to municipal solid waste the Buckeye landfill accepts biosolids. Biosolids contain a range of emerging contaminants. Local community activists are concerned that emerging contaminants will reach the aquifer at levels above the drinking water limit, which is assumed to be 5% of the biosolids concentration. Current practice allows the leachate to mound above base of the landfill liner creating a gradient of 5. The landfill liner is made of clay that is 1.0m thick and has a hydraulic conductivity of 8.0109m/s. Please see Table 1 for additional relevant properties. 1) Will the emerging contaminants ever reach the TrueBlue aquifer? Please justify, with calculations, your answer. 2) Will the emerging contaminants reach the TrueBlue aquifer in 5 years? Please justify your answer. 3) In a maximum of five lines per emerging contaminant describe the use of the emerging contaminant in industry and possible health/ecosystem impacts associated with the emerging contaminants.
