LABORATORY TREATABILITY SERVICES 

Terra System, Inc. (TSI) is one of the most experienced companies in conducting treatability studies having conducted well over one hundred studies to evaluate monitored natural attenuation of organic contaminants, enhanced aerobic bioremediation of petroleum contaminants, and enhanced anaerobic bioremediation of chlorinated solvents.  TSI also has extensive experience conducting treatability studies for in situ chemical oxidation.

In Situ Aerobic Bioremediation Treatability Studies.  TSI personnel have over 2 decades of experience in evaluating in situ aerobic biodegradation of petroleum hydrocarbons ranging from gasoline and diesel to heavier products such as No. 6 Fuel oil.  TSI can evaluate the benefits of inorganic nutrient additions, pH control, or various oxygen sources from sparged oxygen, slow release oxygen compounds, or hydrogen peroxide. 

Monitored Natural Attenuation.  TSI has done a number of assessments of monitored natural attenuation of chlorinated solvents and petroleum hydrocarbons in soils, groundwater, and sediments both in laboratory evaluations and from field monitoring data. 

In Situ Anaerobic Bioremediation.  TSI has conducted numerous anaerobic bioremediation studies over the past 14 years investigating the fate of chlorinated solvents such perchloroethene, trichloroethene, cis-1,2-dichloroethene, vinyl chloride, 1,2-dichloroethane, carbon tetrachloride, chloroform, methylene chloride, Dinoseb, 1,1,1-trichloroethane, 1,1-dichloroethane, 1,1-dichloroethene, and chloroethane.  We can evaluate different substrates, amendments to adjust pH, nutrients, or the need for bioaugmentation to promote the complete dechlorination of the solvents. 

In Situ Chemical Oxidation.  TSI has conducted a number of treatability studies to evaluate the oxidant demand for oxidants such as permangate or persulfate.  TSI has also evaluated the effectiveness of permanganate, persulfate, ozone, and hydrogen peroxide to destroy contaminants from aromatics like benzene, toluene, ethylbenzene, xylenes;  polynuclear aromatic hydrocarbons; chlorinated solvents such as perchloroethene, trichloroethene, 1,1,1-trichloroethane, 2-chloropropene, carbon tetrachloride, and others.

Petroleum Hydrocarbon Utilizer Plate Counts:  TSI can determine the number of culturable total bacteria and numbers of petroleum hydrocarbon degraders.
