RP Environmental, LLC. was formed in 1994 by geologist Patrick Duncan with the idea of performing environmental site assessments for banks and other financial institutions. Since that time, we have grown steadily, and in addition to site assessment work, we also provide wetland delineations and associated permitting, underground storage tank removal and closure services, and geological consulting. To date, we have performed over 3500 projects in Ohio, New York, Pennsylvania, West Virginia, Kentucky, Indiana, and Michigan.
