Free Phosphate <br /> ORC contains up to three percent of food grade potassium phosphate. The <br /> phosphate is specifically KH2PO4, also known as monopotassium phosphate or <br /> MKP and/or K2HPO4, which is dipotassium phosphate or DKP. The <br /> concentration cited is intimately bound to the crystalline structure of magnesium <br /> peroxide. Some may eventually be released since the potassium phosphates are <br /> water soluble. <br /> Even though a portion will remain with the spent product, to be conservative we <br /> may assume it will all be released. If this is the case one has to evaluate the total <br /> volume of water that will solubilize the extant phosphate, in order to derive a <br /> concentration that could permeate the aquifer. It can be easily shown that the <br /> amounts fall below I ppm in the immediate vicinity of the source well. <br /> Qualitatively, several points should be made with respect to the benign nature of <br /> the phosphates in question. First, they are ingestible and harmless; they are used <br /> as meat moisturizers and in baby food. REGENESIS uses a food-grade <br /> product for the extra purity. It is not imperative that it be food-grade pure to be <br /> safe - as the lesser grades are sold as fertilizer. Furthermore, the phosphates are <br /> invariably going to be metabolized by any of the sub-surface microorganisms, <br /> aerobic or anaerobic, as it is a basic nutrient that is essential to life. Its ultimate <br /> fate in living organisms, from microbes to mammals, is that it will become part <br /> of the ubiquitous array of biochemicals that contain phosphate. <br /> R EG E N ES I S -------------- <br /> --------------------------------------------------------------=----------------- <br /> Bioremediation Products 27130A Paseo Espada, Ste 1407, San Juan Capistrano, CA 92675 <br /> Phone: 714-443-3136 Fax: 714-443-3140 <br />
