ACT has been performing Ground-Penetrating Radar and Utility surveys in the northeastern United States for over 15 years. Our survey equipment includes a GSSI's Model SIR 2000 Control Unit with 300 and 500 megahertz antennas, a Subsite Model 75E Utility Locator and a Schonstedt GA-92 Magnetometer. Additional survey equipment is available to fulfill the requirements of a specific project.
Our certified staff of highly trained and experienced professionals will assist you in developing a cost effective scope of work that will systematically scan pertinent portions of a property for any and all underground structures and utilities.
Subsurface Sampling
ACT utilizes GeoprobeŽ-style direct push drilling equipment to sample subsurface environmental media. In its basic form, direct push drilling involves the placement of a sampling device at the tip of small-diameter hollow steel rods and driving the sampling device into the ground utilizing either truck-mounted or portable equipment. Specific sampling devices are designed for Soil Sampling, Soil-Vapor Sampling and Ground Water Sampling.
Our AMS Power Probe 9600 G truck-mounted drill rig has over 30,000 pounds of down force and 37,000 pounds of pull-up force, permitting continuous soil sampling to fifty feet and ground water sampling to more than 100 feet below ground surface. Conventional, cased monitoring wells can also be installed for long-term ground water monitoring. Our portable drilling equipment is ideal for basements, boiler rooms and alleys not accessible by truck-mounted drilling equipment.
Mobile Laboratory
ACT's Mobile Laboratory services include trained personnel and equipment to screen volatile and semi-volatile organic compounds in the field during a subsurface investigation. Our equipment consists of an SRI 8610C Purge and Trap Gas Chromatograph for EPA Method 601, 602, 8010, 8020 or 8021 analyses, a Miran 1A CVF Infrared Spectrophotometer for Total Petroleum Hydrocarbon analysis and hand-held Photoionization Detectors (PID) for instantaneous screening of organic vapors.
The real-time data generated by our Mobile Laboratory can be utilized to select samples for confirmatory analysis or to locate conventional monitoring wells or vapor points. As part of ACT's Phase II Environmental Site Assessments, our Mobile Laboratory provides a vast amount of real-time data about a chemical or petroleum release that reduces the time and cost of the assessment while enhancing the precision of our conclusions.
