Due Diligence (For Homeowners)

The most trusted due diligence services in NJ.

Due Diligence – For Homeowners

Certified Environmental has decades of combined experience in underground and above ground tank removals, soil and groundwater remediation, tank testing/certification, and underground tank property scanning.

Tank Sweeps

Certified Environmental will come out to a property and perform a tank sweep consisting of a physical inspection, subsurface geophysical scan to find abandoned or in-use tanks, and present a report of findings.

Even properties that don’t use oil now may have used oil in the past, so an abandoned tank may exist without anybody knowing about it.  If we find a tank, we will provide a consultation of your options and include our opinions based on our decades of experience.  We can also provide a quote for removing the oil tank.

Don’t buy a property without finding out if an underground tank exists!

Tank Testing

Certified Environmental will advance borings around your oil tank and screen the soil with a photo-ionization detector to provide immediate knowledge of a tank’s integrity.  Soil samples will also be collected from beneath the tank and taken to a NJDEP licensed laboratory to quantify the amount of contamination in the soil.  If no contamination is present, the laboratory will document that the soil is “clean”.  Certified Environmental will present you with a report of findings based on the field screening and laboratory results.

According to The American Petroleum Institute, underground tanks last about 20 years.  Because they are out of sight, they can cause damage without your knowledge.  This damage could occur over years of use and may not be noticeable during the course of the normal tank usage.
