- Magnetometric Detection and tank location services explore all leads that point to the past or present existence of an underground oil tank. Unknown piping, sinkholes in the lawn, oily odor in the basement or crawl space, or presence of copper piping are all investigated.
- Percussion rods are driven into the surrounding soil to verify length, capacity, and direction of the tank.
- Hand Augered or Geoprobe Driven Samples are collected from around an underground tank, and is a more accurate method of evaluation liability than volumetric or pressure testing. Soils are continuously checked down to a 6′-7′ depth for odor and staining. This test method will reveal the presence of soil contamination from a current leaking tank, leaking piping, overspills, and past leaks.
- Tank Certification Soil Samples collected from 0-6" deeper than the tank via the hand auger technique are sealed in Teflon-lidded containers and stored in an ice chest. A sample location map is generated at the time of the sample collection. For active or inactive tanks, water paste is used to detect the presence of unwanted water in the tank
- Formal Analysis is performed according to state guidelines using accepted DEP methodology, providing quantitative certifiable results for field test positive for petroleum hydrocarbons.
- The Certified laboratory Report quantifies the degree of contamination and documents the evidence in a report which is then incorporated into ANCO’s certification.
- No Evidence of Contamination Certificate is issue with ANCO documenting in clear language, certifiable proof that there is no evidence of petroleum contamination in the sample collected.
Tank Removal or Closure
- ANCO has removed or closed over 20,000 tanks since 1981.
- Turn-key service is not reliant upon third party subcontractors.
- Environmental compliance and remediation.
Site regraded upon completion – surface restoration capabilities (i.e. concrete, curbing, asphalt, etc.).
