Some groundwater bioremediation projects utilizing Biodyne's products and services.

This project involved groundwater contaminated from fuel related to a diesel powered generator at a bayfront condominium.  Free product was visible in some wells at the outset of biological treatment.  Other underground pipe in the area led to wide dispersal of the contamination.

A passive treatment approach was selected because of aesthetics and absence of time constraints.  The microbes were grown on-site in "bug jugs" in volumes sufficient to deliver large numbers of microbes into numerous well points which dotted the contaminated area.  The inoculum and mineral nutrients were added to the vent pipes on a weekly basis followed by modest quantities of water to disperse the microbes beyond the immediate area of the well  point casing.

Contaminant levels in all areas of the plume have been reduced to below target levels.

Because older Florida homes used fuel oil tanks for heating before the common use of combined electric heat and air conditioning, groundwater projects with fuel oil contamination are very common.  Evidence of contamination is often discovered during either tank removal or real estate environmental audits.

These projects involve small contaminant plumes, but are often only amenable to biological treatment because of close quarters or under-structure contamination.  Inoculum is added to a system of vent pipes and/or percolation pipes which deliver microbes and mineral nutrients into the contamination plume.

Because of a number of variables, including accessibility of the plume, type and porosity of the soil, depth to the groundwater, et al, these projects have been returned to clean standards in 6 months to two years.

This project involved the discovery of an unexpected underground fuel tank during the excavation for the construction of a new building.   The tank still contained diesel fuel and was badly damaged during the excavation.   Free product was visible on the exposed groundwater.

The contaminated soil was removed to an incinerator, and free product was withdrawn using a skimmer pump into a tanker truck to be hauled to a recycling facility.  The remaining contaminant was treated using liquid inoculum and a circulation/aeration system to speed the petroleum hydrocarbon degradation.

While the "aerobic" bioremediation was allowed to continue for less than a week due to construction deadlines,  the contamination levels in the exposed groundwater dropped enough during that time to meet environmental regulatory requirements and the construction continued.

This project involved groundwater contamination from leaking fuel tanks at a former gas station site.  When the tanks were removed, the contaminated soil was left in the hole for cleanup at a later date.  The contaminant levels of gasoline and diesel remained high five years later when remediation began.

Vent pipes were peppered throughout the plume area.  All contaminated soil removed during the vent construction was removed to the concrete floor inside the vacant gas station where it was treated via inoculation and mixing.  Microbes and mineral nutrients were added to the vent pipes on an on a regular basis.

This project involved groundwater contamination from leaking fuel tanks at a former gas station site.  The tanks were removed and the contaminated soil incinerated.  The contaminant levels of gasoline and diesel fuel were high and part of the plume extended under the building.

Vent pipes were inserted throughout the plume area, including inside the building.  All contaminated soil removed during the vent construction was removed to the interior of the vacant gas station where it was treated via inoculation and mixing.  Microbes and mineral nutrients were added to the vent pipes on an on-going basis.

Contaminant levels in almost all areas of the plume are at or near target levels.
