California USA – A citrus ranch used well water for irrigating the trees.  The water was pumped into a 2-acre holding pond prior to going through the filtration system.  The aquifer had crude oil seeping into the well area that would end up in the holding pond.

BioWorld Products were applied to the pond surface as a regular maintenance program and the crude oil was no longer visible.  The filtration back-flush system had no indications of petroleum hydrocarbons.
