Villanova Chooses ARM for Geothermal Consulting Services

ARM completed a Phase 1 Standing Column Geothermal Feasibility Study for a Villanova University dormitory in January 2009.  After reviewing the local geology, aquifer characteristics, and data for existing wells in the area, ARM correlated this information to the drilling results from a deep test well at the site.  ARM then conducted a step-drawdown test and a 12-hour pumping test to verify the yield capacity, water quality of the well, and the aquifer characteristics at the site.  The testing results were correlated with estimates of mean-monthly groundwater recharge for the local watershed to verify the long-term sustainability of the aquifers at the proposed pumping rates.  The results of this feasibility study were used as part of the design criteria for several planned geothermal systems at the site that will be used to provide heating and cooling for a university dormitory.

ARM was retained to conduct a detailed subsurface investigation that included earth resistivity (ER) surveys following an unsuccessful test well that was drilled by the client prior to ARM involvement.  The primary goal of the investigation was to determine the most favorable locations for the drilling and completion of a closed-loop geothermal well field.  Factors used to determine the location of the well field included: subsurface bedrock conditions including the presence of voids, weathered rock or other potential sources of drilling hazards; and existing infrastructure at the site that could not be relocated

After the ER data were collected and evaluated, ARM’s experienced hydrogeologists identified a location for the well field that would minimize drilling costs and meet the requirements of the geothermal system. This project was completed during fall 2009.
