| Abstract: |
Population density determines the effluent load per unit land area and the concentration of contaminants in groundwater. Numerous studies employing groundwater monitoring and modeling have demonstrated a correlation between water contamination and on-site sewage disposal density. A survey of literature on density of systems indicates that in general a minimum lot size of one-half to one acre is needed to ensure against groundwater contamination. However, some studies have found groundwater contamination from nitrate with lot sizes in this range due to site specific soil, hydrogeologic and climatic conditions. Most studies relating density of on-site sewage disposal systems to groundwater contamination have focused on nitrate loading. Additional research focusing on other effluent constituents is needed to improve our understanding of system density and water quality. |
