Keith Kaufman <br /> Subject: Results of Physicochemical and Microbiological Analyses of Two (2) Water <br /> Samples(GLDM) <br /> ----------------------------------------- --------- <br /> --------------------- -- <br /> Listed below are the results from the referenced analyses performed on two 2 water samples <br /> collected on 9/17/96 and received on 9/18/96. After appropriate dilution,the samples were plated <br /> onto TSA and MSA supplemented with 50 ppm gasoline as sole carbon substrate (per Bob <br /> Marty). Cultures were incubated under aerobic conditions at room temperature for four (4) days <br /> prior to enumeration. Physicochemical analyses were performed in accordance with previously <br /> Idescribed protocol. <br /> RESULTS <br /> Parameter Mw-9 MW-14 <br /> pH 7.1 7:3 <br /> INitrate (ppnn) IQ 4.7 <br /> Nitrite (ppm) 1.8 1.2 <br /> IAmmoniutu (PPM) 3.4 3.4 <br /> i Phosphate (ppm) i 2 0.2 <br /> Potassium.(linin) ';5.3: 3.4: <br /> Gen..Mier.
