Re: Evaluation of effectiveness of bacteriological reduction on your Pure Water Unit Dear Craig Story: Accurate Testing Labs, LLC, performed a series of test on your Pure Water Unit to determine the efficiency of removal of Total Coliform and Fecal Coliform Bacteria contamination. For all the tests conducted, the laboratory tap was the source of the influent water (natural, un-chlorinated groundwater). Total Coliform and Fecal Coliform needed to be added to the tap water, since they are not present. The organisms used for creating contaminated water are Klebsiella Pneumoniae (Total Coliform Bacteria) and Escherichia Coli (Fecal Coliform Bacteria). Materials used for this experiment, other than your Pure Health Unit, are all non-metal, made of polypropylene and of food grade quality. Each of the tests was conducted using the appropriate EPA approved method. As you could see we not only have a modern and clean working environment we also use the most up to date equipment to produce reliable testing results. In summary, the Pure Water Unit destroyed 100% of the introduced amount of Total Coliform Bacteria and E. Coli Bacteria. If you have questions or concerns regarding the test results or you need more information regarding the test procedure, analytical data etc., please do not hesitate to contact Jim or me. Sincerely, Walter Mueller, Laboratory Director Enclosures: Certificate of analysis for influent water, water after pure water unit, list of organism concentration and % removal. |
