New Instrumentation for Water Budget Evaluation

Date

The Delaware Environmental Observation System (DEOS) and the Delaware Geological Survey have recently acquired new instrumentation to measure evapotranspiration (ET). The purchase of an eddy covariance instrument, partially supported by the Department of Natural Resources and Environmental Control, will improve the ability to quantify ET during agricultural and water supply drought periods and improve water availability estimates for resource managers.

Simple ways everyone can act to protect groundwater
Everyone can and should do something to protect groundwater. Why? We all have a stake in maintaining its quality and quantity.
• For starters, 99 percent of all available freshwater comes from aquifers underground. Being a good steward of groundwater just makes sense.
• Not only that, most surface water bodies are connected to groundwater so how you impact groundwater matters.
• Furthermore, many public water systems draw all or part of their supply from groundwater, so protecting the resource protects the public water supply and impacts treatment costs.
• If you own a well to provide water for your family, farm, or business, groundwater protection is doubly important. As a well owner, you are the manager of your own water system. Protecting groundwater will help reduce risks to your water supply.

Assessing Potential Impacts of a Wastewater Rapid Infiltration Basin System on Groundwater Quality: A Delaware Case Study

Date

DGS staff member A. Scott Andres along with J. Thomas Sims of the University’s Department of Plant and Soil Science have had a paper “Assessing Potential Impacts of a Wastewater Rapid Infiltration Basin System on Groundwater Quality: A Delaware Case Study” published in the Journal of Environmental Quality. This paper is the latest technical report from a DGS-led project “Evaluation of Rapid Infiltration Basin Systems (RIBS).” Four additional reports on this project are nearing release in the DGS bulletin series. Information about this project can be found at: http://www.dgs.udel.edu/projects/evaluation-rapid-infiltration-basin-sy…
