Loudoun County Health Department

Third-party hydrogeologic review for public health oversight

Loudoun County, Virginia relies on private wells and groundwater systems to serve residential, agricultural and industrial development, making rigorous hydrogeologic oversight a direct public health matter.

ECS Group of Companies was engaged by the Loudoun County Health Department (LCHD) to conduct third-party technical reviews of hydrogeologic reports submitted as part of the Facilities Standards Manual (FSM) compliance process, covering residential subdivisions, irrigation wells and industrial developments.

Challenge: Verifying groundwater resources to support healthy progress

Hydrogeologic reports submitted to the Loudoun County Health Department varied widely in technical rigor, requiring independent verification of calculations, methods and FSM compliance across multiple development types, with groundwater adequacy determinations directly affecting whether proposed projects could move forward.

Solution: GIS-database to help resolve 14 report assertions

ECS built a GIS database to verify report assertions, reviewed digital testing data to assess calculation accuracy and delivered findings across 14 hydrogeologic reports for LCHD since December 2019, with prior reviews for Loudoun County Building and Development dating to 2018.
