Certain circumstances or inaccessibility may require an underground oil storage tank to be abandoned in place rather than removed. D.R. Charles Environmental Construction performs legal abandonments of underground storage tanks. Our preferred method of abandoning underground tanks is by using Tri-Polymer® Foam versus sand. Tri-Polymer® Foam has been used for over 30 years nationwide as a permanent, inert, environmentally safe tank abandonment medium.
D.R. Charles will pump out any remaining oil and sludge from the underground tank, clean the inside, bore through the bottom of the tank to obtain a soil sample from beneath the tank, provide Extractable Total Petroleum Hydrocarbon (ETPH)
test results by a state certified laboratory, and supply the property owner with a certified letter documenting the legal abandonment.
