1 <br /> 1 <br /> • Inorganic Chemistry and Nutrient Assays <br />' Analysis Request Nutrient assays were requested for dissolved oxygen (DO), oxidation- <br /> reduction potential (ORP), pH, ammonia nitrogen, ortho-phosphate, sulfate, nitrate, and ferrous <br />' iron II <br /> Protocol. Spectrophotometric assays were performed to determine the concentrations of <br />' ammonia, ortho-phosphate, sulfate and nitrate The assays follow EPA manual colorimetric <br /> protocols using precalibrated reagents and a Bausch & Lomb spectrophotometer 20 All assays <br /> conform to California CLP and Standard Water& Wastewater Methods <br />' The testing for ferrous iron and alkalinity were subcontracted out to Curtis & Tompkins, Ltd <br /> Analytical Laboratory in Berkeley, CA (5M3500-FE) <br /> I <br /> Chemical and Inorganic Assays <br />' ortho- Nitrate Ferrous <br /> Client DO H Ammonia Phosphate Nitrogen Sulfate Iron <br />' Sample mg/L ORP ORP mg/L mg/L mg/L mg/L Alkali mg/L <br /> Number m mV m) m m m -nr m <br /> MW-1 39 59 394 09 05 188 121 <br /> MW-4 4 1 6 0 400 1 4 1 0 2 9 138 <br />' MW-5B 3 7 6 2 406 0 9 0 5 0 4 78 <br /> MW-8 4 2 64 404 1 1 0 7 0 5 199 <br /> Reporting limit for the colorimetric chemistry assays is 0 1 mg/L <br /> Reporting limit for ferrous iron is 0 10 mg/L <br /> Reporting limit for alkalinity is 1 0 mg/L <br /> CytoCulture is available on a consulting basis to assist in the interpretation of this data and their <br />' application to field bioremediation protocols <br /> J s ita Tablante Randall von Wedel, Ph D <br />' aboratory Technician Principal Biochemist <br />' C\cytolab\lab reports\Clearwater\Water 03-210 <br />
