Precision Assessment Technology knows the drill: to provide drilling services for environmental site assessment and remediation. Formerly Conor Pacific Group, the company works through US-based subsidiary Precision Sampling Inc. (PSI) and Trenchless Specialties to serve environmental and geotechnical engineers and other clients who collect soil and groundwater samples for analysis. The group's services, provided from offices in California, Florida, and North Carolina, are used primarily for soil redevelopment and water treatment. The company's work sites range from small dry-cleaner locations to extensive military bases. The financially struggling firm sold its B2 Environmental subsidiary in 2008.
