IN-SITU CONTAMINANT REMEDIATION OPTIONS

• Petroleum hydrocarbons; gasoline, diesel, motor oil, BTEX, MTBE, TBA and other compounds: treat with aerobic enhanced bioremediation, chemical oxidation (ozone), or hydrogen peroxide, Fenton's chemistry.
• Chlorinated Solvents; PCE, TCE, DCE: Treat with anaerobic enhanced bioremediation or chemical oxidation or hydrogen peroxide, Fenton's chemistry.
• Nitrates and Perchlorate: Treat with anaerobic enhanced bioremediation.
• Heavy Metals: Solubility and mobility of heavy metals (chromium, lead, cadmium, arsenic, etc.) is pH sensitive. Besides pH adjustment, metals stabilization may involve adding a reductant or oxidizer, depending on the metal.

OVERVIEW OF IN-SITU SOIL AND WATER TREATMENT:

Environmental Bio-Systems specializes in soil, groundwater and process water treatment assessment and remedial technologies. Some applications for soil and groundwater contamination are in -situ (in place) such as chemical oxidation, enhanced bioremediation, and metals stabilization. Above ground applications also relate to groundwater treatment, process wastewater minimization, treatment, and resource recycling.

Numerous in-situ technologies have been developed over the past few years. Delivery is the key issue for in-situ remediation, whether it is the delivery of the oxidants for chemical oxidations, the reductants for metals stabilization or nutrients and electron donors for enhanced bioremediation. Generally, in-situ remediation costs less than conventional methods: excavation and off-site disposal for soil, and pump and treat for groundwater. Nonetheless, in-situ projects do require more planning and scientific skill to implement than conventional methods.

Environmental Bio-Systems can make arrangements for "wait and pay" status (90-120 days) from State Underground Storage Tank Funds.
