Groundwater Withdrawals

New policies and technical approaches have recently emerged to address surface water/groundwater interactions, treatment, and permitting issues. The current trend toward increased regulation of groundwater sources that have the potential for impact by surface water is referred to as groundwater under the direct influence (GUDI).

New groundwater sources need to be carefully designed and located to minimize water quality problems caused by the influx of untreated surface water. Serious health effects can be caused by the presence of water-borne protozoans and other microbial pathogens such as Giardia lamblia cysts and Cryptosporidium. In an effort to optimize water quantity by inducing infiltration from nearby surface water bodies, some existing pumping systems have experienced deteriorating water quality related to GUDI of surface water. Skelly and Loy’s professional hydrogeologists possess extensive experience in the collection, analysis, and interpretation of data used to identify pumping impacts on streams, wetlands, and other surface water receptors. These data are routinely collected in the early stages of developing new groundwater sources (wells) to establish background water level conditions, isolate any effects due to pumping, and establish safe, sustainable yields for groundwater supply wells.

Skelly and Loy has more than 27 years of experience successfully completing groundwater development and water quality treatment projects. In addition, we are experienced with working with the regulatory community (e.g., PA DEP, Susquehanna River Basin Commission, Delaware River Basin Commission, U.S. Environmental Protection Agency) for permitting and managing new groundwater sources. Let our hydrogeologists assist you with your next project.
