Sussex County groundwater report issued

Sept. 2, 2015--The Delaware Geological Survey (DGS) has released a new technical report titled Simulation of Groundwater Flow and Contaminant Transport in Eastern Sussex County, Delaware with Emphasis on Impacts of Spray Irrigation of Treated Wastewater. 

Prepared by Changming He and A. Scott Andres, DGS Report of Investigations No. 79 documents development of a detailed study of subsurface hydrogeology, interactions between aquifers and streams, and the effects of spray irrigation of treated wastewater on groundwater beneath southern eastern Sussex County.

With increases in computational power and capabilities of software, numerical models have become state-of-the-practice for characterization of groundwater flow and contaminant transport and water-resources management.

This report documents the results of a study in which a three-dimensional numerical model was used to simulate groundwater flow and quality in in the Columbia, Pocomoke and Manokin aquifers and intervening confining beds.
