Effects Of Agricultural Practices And Septic-System Effluent On The Quality Of Water In The Unconfined Aquifer In Parts Of Eastern Sussex County, Delaware

Abstract

The unconfined aquifer is a major source of water supply in eastern Sussex County, Delaware. It also is an important source of water for surface-water bodies and deeper, confined aquifers. The aquifer consists mainly of permeable sand and gravel; its shallow water table is susceptible to contamination by nitrate and other chemical constituents associated with agricultural practices and effluent from septic systems.
