„ _M _( S0LMAR COQ <br /> TREATMENT OF CONTAMINATED SOILS <br /> The use of Solmar Advanced Bio Cultures in bioaugmentation <br /> programs has proven to be a very cost effective means of dealing <br /> with many environmental problems. Of special note is the <br /> increasing use of our cultures for -on site treatment of soil <br /> contamination ' involving diesel fuel and other petrochemical <br /> products. <br /> The following outlines details on typical treatment <br /> requirements for 1 ,000 cubic yards of diesel contaminated soil <br /> {-average contamination of 2 , 500 ppm) . - Should there be a question <br /> - _" -df inhibition caused by. any other ' contaminants present, . a <br /> representative 1 lb soil sample should be' sent to our lab for a <br /> toxicity test for which there is no charge. <br /> _ A sufficient quantity of fertilizer has to be added and <br /> _thoroughly mixed with the contaminated soil to furnish 100 pounds wa{rr <br /> of nitrogen pe-r - 1 ,-000` cubic yards of soil . This means that 650 s©� <br /> `pounds of 15-15-=15 fertilizer would be required for each 1 ,000 <br /> cubic yards of a - project. Fertilizer with higher numbers are <br /> available, but may not be water soluble. This should be checked <br /> out with the local suppliers in your area. <br /> After the fertilizer has been added and thoroughly mixed <br /> in, necessary water should be added to bring total moisture <br /> content to at least 20, but not higher than 80 percent of <br /> saturation levels. After waiting two days , the initial <br /> inoculation dosage of 50 pounds of our L-104 cultures premixed <br /> wi-th water at a ratio of one pound to at least two gallons of <br /> water should be soaked for at least four to six hours before <br /> application. Two weeks after the initial inoculation, another 25 <br /> pounds of presoaked cultures is to be added and mixed into the <br /> soil . <br /> Thirty days after this, another application of 25 pounds of <br /> presoaked cultures is to be added and mixed into the soil . The <br /> foregoing dosage rates are designed for optimum degradation. <br /> Mixing and tilling is to be done at least once a week to allow <br /> the fastest degradation, since tilling not only aerates but <br /> maximizes the interface contact of the cultures with the <br /> contaminants. Mixing and moisture level maintenance will be <br /> required from here on until designated degradation levels are <br /> abhieved. <br /> Solmar Advanced Bio Cultures are packaged in 25 pound <br /> quantities in heavy duty plastic pails. Total product required <br /> to treat 1 ,000 cubic yards is 100 pounds of our L-104 <br /> formulation. <br /> As a result of the many successful projects that have tised <br /> our ABC Cultures, we truly feel that bio-remediation offers the <br /> most cost effective -means of dealing with soil cleanups and <br /> welcome the opportunity of working with you on them. <br /> While this procedure outlines a typical project, most ' <br /> situations are site specific. Please call us to discuss <br /> variables such as type of contamination, degree of contamination, <br /> expected level to be. achieved, soil types, or anything unique . <br /> If bioremediation is of interest , but for one reason or <br /> another the "land farming technique” presents some problems , we <br /> may be able to suggest other approaches as a solution to your <br /> site . <br /> 050-049 625 West Estella Ave. , Suite 5, Orange, CA 92667 • (714) 538-0881 <br />
