Reason NO. 23 Why ESI Should Perform Your Next GPR Tank Sweep !

LITTLE SILVER, N.J. - June 16, 2019 - PRLog -- Purchasing a new home is possibly is the most expensive purchase a person can make. Using the ' Lowest Price Oil Tank Sweep" may not be in ones best interest as having a oil tank sweep completed with just a  Metal detector is basically a waste of money and typically does not satisfy the purchasers " Due Diligence' requirement under the innocent purchaser protection laws of New Jersey.  Environmental Systems uses Ground Penetrating Radar to scan the entire property as oil and gas tanks can be located anywhere on the property not just within 10 feet of residential structure. Ground Penetrating Radar is highly sensitive and can find buried metal or non metal objects down to 18 feet below surface grade level, while a metal detector can not see through asphalt and concrete and is only sensitive to a depth of maybe 2 feet on good day.  Environmental Systems has identified metal piping, sink holes , concrete septic systems and buried construction debris. During an Oil Tank Sweep with Ground Penetrating Radar it is not uncommon  to find subsurface anomalies that can be positively identified. Sometimes these images are real and a filed in place oil tank if found and in other circumstances a tin can  or metal nails can provide a false reading. Environmental Systems always recommends extra cost soil borings , as this gives the investigator the opportunity to identify what the soil conditions are like. Some oil tank companies just stick a probe rod in the ground. This is a poor techniques as a water line or gas line can be easily damaged and the structure that is in ground can not positively identified. Soil boring allows the scientist to sample soils every 6-10 inches and each discrete sample can be
scanned with a Photo Ionization Detector to see if the sample contains petroleum produces like gas or oil or chlorinated solvents like carbon Tetra Chloride.   Recently we performed a Oil tank sweep in Monmouth county and the client decided to pay the additional fee to have the soil borings completed. No oil tank was found but a Chlorinated Solvent plume was found 2 feet from the structure. If the buyer purchased the property without proper NJDEP Supervised remediation there may have been a Vapor Intrusion Problem that could have caused the new occupants to have health and other respiratory problems. Ground Penetrating Radar shows a screen image of soil disturbances, a Environmental Geotechnical expert can determine what each of the images found on screen represent. Many home inspector provide oil tank sweep services but very have a Environmental Scientist or Environmental Expert credentials to backup there readings and oil tanks or environmental issues are often missed. Again just because find a oil tank does mean the property is not contaminated with heating oil..  Environmental Systems is a full service Environmental Company providing Tank Services, Remediation and Site Investigation services.  To obtain additional information contact Environmental  Systems at 732-892-8707 or visit our website at www.allenvirosystem.com
