Water levels, chloride concentrations, and pumpage in the coastal aquifers of Delaware and Maryland
D. J. Phelan
1987, Water-Resources Investigations Report 87-4229
The Manokin, Ocean City, Pocomoke, and unconfined aquifers of coastal Delaware and Maryland are susceptible to saltwater intrusion from inland movement of offshore water, and from vertical leakage from the bays and deeper aquifer. Comparison of data for water levels, chloride, and pumpage affected during 1974-86 shows that, with the...
