DGS and DEOS are pleased to announce that near real-time groundwater level data from well Oh25-09 have recently been made available on the DEOS web site through the Harbeson, DE-REC station found on the Current Conditions link (http://
The Delaware Geological Survey released a new technical report entitled “Hydrogeology of a Rapid Infiltration Basin Systems at Cape Henlopen State Park, Delaware” which was prepared by A. Scott Andres and Changming He of the Delaware Geological Survey, Edward Walther of the South Water Management District, Florida, and Müserref Türkmen of the Izmir Water and Sewerage Administration, Turkey, and DGS Bulletin 21B documents the results of a detailed study of groundwater and hydrogeology at a rapid infiltration basin system.
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, which was prepared by Changming He and A. Scott Andres of DGS.
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.
This report presents a conceptual model of groundwater flow and the effects of nitrate (NO3-) loading and transport on shallow groundwater quality in a portion of the Indian River watershed, eastern Sussex County, Delaware. Three-dimensional, numerical simulations of groundwater flow, particle tracking, and contaminant transport were constructed and tested against data collected in previous hydrogeological and water-quality studies.
Peter P. McLaughlin, Jr., Senior Scientist at the Delaware Geological Survey, gave a presentation on October 18 at the 2014 Geological Society of America Annual Meeting in Vancouver, Canada entitled "Application of 3-D Aquifer Mapping to Analysis of Groundwater Withdrawals by Source in the Delaware Coastal Plain," coauthored with Jaime L. Tomlinson and Amanda K. Lawson.
