Groundwater Monitoring Network Infrastructure Expansion – Sussex County, Delaware

The DGS has begun a multi-year project to install new groundwater monitoring infrastructure and collect baseline data in Sussex County, Delaware. This project is a continuation of a larger effort to construct a statewide groundwater monitoring network.

Assessing spatial distributions and vulnerability of stored soil carbon in St. Jones and Blackbird Marshes

Project Contact(s)

Delaware is home to extensive networks of tidal marshes, which provide an array of critical ecosystem services including carbon sequestration. These marshes accumulate carbon due to their relatively high plant productivity and relatively low rates of litter decomposition.

DGS joins Project WiCCED

Date

DGS staff members Rachel McQuiggan and Scott Andres are participants in a new National Science Foundation EPSCoR – funded effort, Water in the Changing Coastal Environment of Delaware (Project WiCCED).

RI79 Simulation of Groundwater Flow and Contaminant Transport in Eastern Sussex County, Delaware With Emphasis on Impacts of Spray Irrigation of Treated Wastewater

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.
