Diesel-Fired Power Plant Remediation

Belize Electricity Limited (BEL) contracted Trihydro to remediate petroleum hydrocarbon impacts at five of their diesel-fired power stations. The project involved soil quality investigations, a groundwater quality assessment and monitoring program, and excavation paired with bioremediation.

Treating Impacted Soils

Trihydro’s project team designed and constructed a 750-cubic-meter geomembrane-lined bioremediation cell to treat impacted soils. Over 1,300 cubic meters of impacted soil were excavated from the five project sites, transported, and treated. The team also remediated impacted shoreline soils and sediments in an estuary lagoon immediately adjacent to one of the power stations.

Trihydro provided bilingual project-specific health and safety training for local contractors, workers, and project managers. Local contractors performed most of the fieldwork, which positively impacted the client’s community relations and the local economy.

Preventing Future Contamination

Based on the initial project’s success, BEL subsequently contracted Trihydro to implement a company-wide spill prevention project to create on-the-ground infrastructure to prevent re-contamination at the diesel-fired power plants. As part of this project, Trihydro designed and provided construction oversight for secondary containment areas, loading/off-loading areas, and oil/water separators to control stormwater and prevent releases of hydrocarbons.
