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.
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.
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.
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…
The Delaware Geological Survey (DGS) has published a report that details new findings on the subsurface geology of the Delaware City area.
Titled Subsurface Geology of the area between Wrangle Hill and Delaware City, Delaware, Report of Investigations Number 78 presents the results of cooperative research between geological consultant John W. Jengo of the firm MWH Americas and DGS researchers Peter P. McLaughlin Jr. and Kelvin W. Ramsey.
