Chemical analyses of water samples from domestic, agricultural, public, and monitoring wells document the effects of past and present land use practices. Groundwater flow paths and flow systems are inferred from flow-net analysis, ground-water chemistry, and isotopic composition.en-USSussex County, DelawareColumbia aquiferfresh watergroundwaterflow pathflow systemTechnical Report
