Blake Downey, P.G.

Blake Downey received his professional geologist licensure in 2014 and has over eight years of experience as a hydrogeologist conducting groundwater assessments and evaluating the performance of remediation systems. He has conducted evaluations of monitored natural attenuation, examining the reductive dehalogenation of chlorinated organic compounds and petroleum constituents in groundwater. Mr. Downey's background includes hydrogeology/watershed science and spatial analysis and interpretation of data.
