Ms. Maxine Stewart <br />ITEC Environmental Colorado, Inc. <br />August 7, 2000 <br />Page 2 <br />approximately 200 mL of sample water before the laboratory container was filled. Filters and tubing were <br />used for only one sample and subsequently disposed. <br />Indicator water quality parameters, including pH, temperature and specific conductance were <br />monitored for both samples, as well as other pertinent data such as observed color and any noticeable <br />sedimentation. This information was recorded on the attached Groundwater Sampling Record forms. The <br />field parameters for each sample are summarized in the table below. <br />Sample <br />Identiticatiom Sample <br />Date Water Level <br />(ft bloc) pH Temperature (C) Specific Conductance <br />@25C (umhos/cm) <br />Well #1 7/25/00 18.59 ft 7.38 11.1 1197 <br />Hazel A Adit 7/25/00 NA 7.81 11.9 1040 <br />bloc: below [op of steel casing; <br />NA: Not Applicable. <br />Immediately after sample collection, laboratory containers were sealed, labeled and placed in anice- <br />cooled, insulated chest for storage, pending delivery to the laboratory. Chain-of-custody forms were <br />completed and signed by the field personnel and placed inside the ice chest. Water samples collected during <br />the 2000 sampling event were transported by MFG personnel, under chain-of-custody, to Hazen Research, <br />Inc. lacated in Golden, Colorada. The requested analyses, as indicated an the chain-of-custody forms, <br />included the following parameters: dissolved arsenic, dissolved manganese, dissolved zinc, sulfate and total <br />dissolved solids (TDS). It is our understanding that analytical results will be transmitted directly to ITEC for <br />review and submittal to regulatory agencies, as necessary. <br />If you have any questions regarding any of the information presented in this report, including the <br />attachments, or if you require any additional assistance in connection with this monitoring event, please do <br />not hesitate to contact us. <br />With Regards, <br />MFG, INC. <br />~~~ <br />Jon Friedman, P.E. <br />Project Engineer <br />Pamela Anderson <br />Senior Staff Hydrogeologist <br />Attachments <br />Ja5461 W NN2000.L1R.wpd <br />
