Howard Hughes Medical Institute, Loudoun County, Virginia

The Project

The Howard Hughes Medical Institute (HHMI) built the largest medical facility of its kind in the Nation. Due to the high expense of purchasing potable public treated water supply, it was imperative that groundwater resources be developed on-site to meet their irrigation water needs. Originally,HHMI hired an engineering consultant with hydrogeologists on staff to conduct a groundwater investigation. This previous consultant drilled a total of nine exploratory test wells; each of the nine wells yielded less than 5 gallons per minute (gpm).

EGGI was subsequently contracted to explore for and develop groundwater resources on this 500+ acre parcel of land.

Status/Results:

 EGGI completed its groundwater exploration and development investigation and needed to drill only one well to meet the entire water supply needs of the project.  EGGI identified and drilled one exploratory test well that yielded 350 gallons per minute (500,000 gallons per day).  The water developed on-site is used to irrigate the entirety of the medical research facility.  This project was considered an extraordinary success, particularly in light of the failures of others to find a satisfactory groundwater source at this site.
