Delaware Geological Survey Issues Report on Wastewater Treatment used for Rapid Infiltration Basin Systems

Date

The Delaware Geological Survey released a new technical report entitled “Evaluation Of Wastewater Treatment Options Used In Rapid Infiltration Basin Systems (RIBS)” which was prepared by Müserref Türkmen of the Izmir Water and Sewearge Administration, Turkey, A. Scott Andres of the Delaware Geological Survey, Edward Walther of the South Water Management District, Florida, and William Ritter and Anastasia Chirnside of the University’s College of Agriculture and Natural Resources. DGS Bulletin 21A documents the results of a detailed study of wastewater treatment plant technologies and effectiveness of treatment types that are used to treat wastewater prior to disposal into the ground by rapid infiltration basin systems.

B21A Evaluation of Wastewater Treatment Options Used in Rapid Infiltration Basin Systems (RIBS)

This technical report evaluates several aspects of potential environmental risks, use, and regulation of rapid infiltration basin systems (RIBS) in Delaware. The report reviews and compares regulations regarding RIBS from Delaware, Florida,North Carolina, New Jersey, Maryland, and Massachusetts. Influent and effluent samples from ten advanced wastewater treatment systems that operate in conjunction with RIBS were collected and analyzed.

Drought Conditions Indicators for Delaware

The DGS will research past performance of the Water Conditions Index (WCI) for Northern New Castle County, as compared with other established drought indicators, and investigate modifying the WCI, if needed. We will also investigate the feasibility of quantifying water conditions in Kent and Sussex Counties by analyzing factors that are most important to these regions (i.e., precipitation, groundwater for agricultural irrigation, etc….)

From where should beach replenishment sand come?

Date

Delaware, Maryland and Virginia have each partnered with the Bureau of Ocean Energy Management to find new sand sources using existing mapping data. As part of the federal Disaster Relief Appropriations Act of 2013, which allocated $13.6 million to the bureau, all three states will each receive $200,000 for the two-year project.
