General Lab Comments <br /> Per method recommendation(section 4.4),Samples analyzed by methods EPA 300.0 and EPA 300.1 have been filtered prior to analysis. <br /> The following is an interpretation of the results from EPA method 9223B: <br /> A result of zero(0)indicates absence for both coliform and Escherichia coli meaning the water meets the microbiological requirements of the <br /> U.S.EPA Safe Drinking Water Act(SDWA).A result of one(1)for either test indicates presence and the water does not meet the SDWA <br /> requirements.Waters with positive tests should be disinfected by a certified water treatment operator and retested. <br /> Per federal regulation the holding time for the following parameters in aqueous/water samples is 15 minutes:Residual Chlorine,pH,Dissolved <br /> Oxygen,Sulfite. <br /> Per NDEP-BMRR requirements,the analyses conducted on an extract from a Humidity Cell Testing(HCT),or Meteoric Water Mobility <br /> Procedure(MWMP)are analyzed on a coarse filtered aliquot with the exception of Trace Metals,which are filtered through a 0.45 micron filte. <br /> DF=Dilution Factor,RL=Reporting Limit(minimum 3X the MDL),ND=Not Detected<RL or<MDL(if listed) Page 3 of 10 <br /> SPARKS ELKO LAS VEGAS <br /> 475 E.Greg Street,Suite 119 1084 Lamoille Hwy 3230 Polaris Ave.Suite 4 <br /> Sparks,Nevada 89431 Elko,Nevada 89801 Las Vegas,Nevada 89102 <br /> tel(775)355-0202 tel(775)777-9933 tel(702)475-8899 <br /> fax(775)355-0817 fax(775)777-9933 fax(702)622-2868 <br /> EPA LAB ID: NVO0925-ELAP No:2523 EPA LAB ID:NVO0926 EPA LAB ID:NVO0932 <br />
