Bioremediation of Oil in a Retention Pond

This case study is about bioremediation of oil in a retention or holding pond.

I’ve run into a number of these types of projects through the years. Typically in the dry months, the pond has little to no water. Once a hard rain comes, the water in the pond has a oil sheen. Additionally, the water may or may not have a petroleum smell.

This type of situation is perfect for bioremediation using bioremediation bacteria such as Custom HC. Custom HC is a microbial product manufactured by Custom Biologicals and containing petrophilic bacteria.
