Ground Penetrating Radar (GPR) and Magnetics

Brinkerhoff's inventory of subsurface tools now includes high resolution GPR tied to a satellite global positioning system (GPS) and the latest magnetic imaging equipment. Our innovative technologies are capable of detecting buried tanks, drums, foundations, septic systems, groundwater contaminant plumes and other adverse environmental conditions in a variety of subsurface conditions to depths of 15' and greater. These high-tech devices are computer monitored and capable of remotely sensing and identifying subsurface anomalies -- an invaluable tool when looking for environmental hazards. Once an anomaly is identified, probes, drilling or excavating equipment can be used to determine the extent of the identified anomaly.

GPR is an efficient, accurate, field system for locating anomalies that can be relocated in the field within minutes. The high-accuracy satellite GPS does not require survey equipment or multiple field personnel. When a survey is conducted in a large open lot, or when buildings are demolished and reference points change, our GPS system is tested and accurate for subsurface anomaly identification.

Brinkerhoff is performing geophysical investigations and processing data in the field, so that anomalies can be identified in real time, reproduced and verified, and data can be displayed while the job is underway. Time and cost savings are realized as data can be field-loaded into a notebook computer for data processing in three dimensions. Our GPS system produces instantaneous, accurate results.

Brinkerhoff Environmental is using GPR at the following locations: Academic Campuses Demolition and Redevelopment Sites Golf Courses Gas Stations and Chemical Plants Municipal Complexes Mines and Quarries Residential and Commercial Properties Urban Sites, including Brownfields
