The paper is a case study of a successful biological remediation cell (biocell) that was constructed and is being used in Kenai, Alaska. The cell was constructed to remediate petroleum hydrocarbon-contaminated soil. Biological remediation is a promising technology that can prove both environmentally friendly and cost effective in the treatment of petroleum hydrocarbon-contaminated soil. A biocell can be easy to construct and operate. The biocell utilized an enclosed treatment area and a sprinkler system to saturate the contaminated soil. The excess water was drained to a sump where it was pumped to holding tanks and profiled. Any nutrients or adjustments necessary to promote rapid biological growth and degradation were noted and performed. The project has proven to be successful and beneficial to the overall remediation project which was undertaken.
