Contaminated Sites Calculators

Cleanup Levels Calculator

Petroleum Cleanup Levels Calculator

Cumulative Risk Calculator

Hydrocarbon Risk Calculator

The Hydrocarbon Risk Calculator (HRC) is no longer consistent with how site-specific cleanup levels are calculated under 18 AAC 75, due to the promulgation of new regulations on November 6, 2016. Because the HRC was developed by a third-party and not by ADEC, the department cannot make revisions to the HRC in order to make it consistent with the new regulations.
