Once a leaking underground storage tank is removed and soil contamination identified, Tank Solutions is able to respond immediately while the excavation is still open. Our field crew will install test trenches within the excavation and collected grab samples for field evaluation by our Sub Surface Evaluator. Utilizing high-tech field instrumentation, our Subsurface Evaluator can present a Not to Exceed Remediation Cost proposal which can be implemented same day allowing for a No Further Action Letter to be in hand within 14 business days.
While most remediations involving home owner tanks are manageable in a single event, there are those rare occasions that the soil contamination migrates under structure, over a large portion of the property, off-site or impacts ground water. In these circumstances, project specific work plans are easily provided once a formal delineation investigation with a geoprobe is completed. Tank Solutions has the in-house engineering, experience soil scientists and years of construction experience to handle any size remediation project.
For those entrepreneurs who wish to purchase a property with an active underground heating oil tank, Tank Solutions can assist with the pre-purchase business risk investigation. Tank Solutions will arrange for soil borings to be installed around the active tank by our licensed driller. Each soil core will be evaluated in the field by our Subsurface Evaluator for evidence of a release. A single soil sample will be sent to a NJ Certified Laboratory for confirmatory testing for evidence of a discharge. The field and lab data, once evaluated will allow Tank Solutions to guarantee a Not to Exceed cost for the tank removal/remediation which will be provided in writing and something the buyer can rely on during sale negotiations.
The NJ Department of Environmental Projection mandates that a groundwater investigation be performed if and when groundwater is found around any portion of a leaking underground oil tank or when the underground oil tank is within (2) ft of groundwater as well as bedrock. In these situations, ground water sampling is required to achieve case closure. Groundwater samples are collected either by temporary wells or permitted wells depending upon the specific site characteristics.
The NJ Department of Environmental Protection allows pre-qualified environmental professionals fluent in Subsurface Evaluations to investigate and remediate Unregulated Heating Oil Tank sites with limited oversight by the Department. The Subsurface evaluator is responsible for chronicling the remediation process, determine in the field when the remediation is completed, determine if a ground water investigation is required and to collect confirmatory post remediation soil samples before the site work is completed. All field notes, soils sampling data and observations are compiled into a Remedial Action Report which once completed, is forwarded to the NJDEP for review and approval. Once all review fees are paid in full, the NJDEP will issue the homeowner a letter of No Further Action which officially closes out the incident.
