Harrisburg Area Geological Society

HAGS

The purpose of the Harrisburg Area Geological Society (HAGS) is to stimulate geologic thought, advance and disseminate geologic knowledge, and provide fellowship amongst area individuals interested in earth sciences. Monthly meetings (at GTS Technologies at 441 Friendship Road in Harrisburg) present a realm of geologic topics, ranging from tectonics, coal, carbonate groundwater geochemistry, Martian geomorphology, engineering geophysics, nuclear waste repositories, and ore mineralogy. Field trips allowed members to visit geologic sites within and beyond Pennsylvania. All events are open to the public and free unless otherwise stated. Meetings are at GTS Technologies, 441 Friendship Rd, Harrisburg, PA 17111. They occur at 6:30 PM on the second Thursday of the month, except summer months.

Nitrates in Rural  Groundwater Supply Wells not from Farming: An Unexpected Finding Based on Forensic Hydrogeology

Presented by:Mark W. Eisner, P.G., President – Advanced Land and Water, Inc. (Maryland)

Abstract: Sharptown, MD, is located in an agriculturally-dominated area of the Delmarva Peninsula. Supplied by four wells, groundwater quality compliance samples have reflected elevated nitrate concentrations for years. Non-point agricultural sources were the suspected source, but a detailed study as a component of an updated Source Water Protection Plan assessment revealed a surprising interpretation. End-Member Mixing Analysis (EMMA) – a common surface water investigative technique – was applied to groundwater quality data from the supply wells. Chloride and nitrate tracers, combined with knowledge of local land uses and consideration of the probable condition of aging infrastructure, to support a hypothesis that sewer system leaks rather than agriculture explained the observed nitrate distribution.  Geochemical tracers such as methylene blue active surfactants (MBAS), which are classical indicators of domestic sewerage, were sampled for to confirm the sewage leak hypothesis.

Speaker Bio:  Mr. Eisner is President of Advanced Land and Water, Inc., and has nearly 30 years of experience in environmental and hydrogeological consulting. He earned his B.S. in Geology from the University of Maryland and his M.S. in Geology from the University of Delaware. Possessing more than 30 years’ professional experience, Mr. Eisner directs environmental and hydrogeologic investigations for both private and public sector clients across the Mid-Atlantic region, including projects entailing groundwater supply exploration, development, testing, permitting, protection and discharge.
