Anatomy of a LUST (continued)

Remediation at the Source

Once the extent of gasoline contamination is determined, a remedial plan is devised, approved, and implemented. The first step in cleaning up, or remediating, a LUST site is removal of the leaking tank. Tanks are removed by excavation.

In some cases, contaminated soil is also removed and trucked to a hazardous waste facility for disposal or remediation (incineration, biological treatment).

Thank You! BASIN was a community project which benefitted from over 1000 hours of public volunteer time. BASIN was highlighted by the US EPA in a national case study in its 2001 handbook Delivering Timely Environmental Information to Your Community. Thank you to all volunteers, and especially to the late Jim Waterman, BASIN Project Coordinator!

BASIN was supported by the US EPA, the City of Boulder, the Keep it Clean Partnership, BCWI and BCN
