ETTL offers a full range of services to clients who have underground and/or aboveground petroleum storage tanks (USTs and/or ASTs) located on their property, helping them make sure they will be in compliance with Federal and State regulations designed to protect ground-water against contamination resulting from leaking tanks. ETTL is equipped to test to determine if leaks and contamination are present, the types and 
degrees of such contamination, what remediation might be necessary, and to carry out the actual remediation steps, as required. At right, a site severely contaminated by leaking aboveground PSTs is being remediated by ETTL, using its own specialized bioremediation technique, spraying on a solution containing microbes, surfactants and other proprietary agents. (For more information on ETTL's bioremediation technique, click here.)
ETTL addresses PST problems in accordance with EPA's Federal Technical Requirements40 CFR 280, and Texas Regulations as outlined under Texas Administrative Code, Chapter 334, as well as other appropriate regional regulations. Procedures employed by ETTL when such tanks contain petroleum products, for example, include drilling, sampling and analysis of soils for the presence of benzene, toluene, ethyl benzene, xylenes, and total petroleum hydrocarbons, performing such tests in accordance with EPA protocols. Other parameters are used for the various other materials commonly stored in tanks. ETTL maintains liaison with regulatory agencies to insure that remedial work involved with USTs and ASTs conforms to appropriate regulations. The company is highly experienced in all of these areas.
