Water, Waste & Land, Inc. Statement of qualifications <br />• 16 <br />Ground Water Investigation (Centerline Circuits) Boulder, Colorado <br />Water, Waste & Land, Inc. is assisting with delineation of an organic chemical <br />plume in ground water near a former circuit board assembly facility. Work performed has <br />included borehole drilling, installation of monitoring wells, collection of water quality <br />samples and interpretation of the data collected. Recent emphasis has been on collection <br />of water quality samples from domestic wells within the general study area. <br />Green Mountain Mine (Green Mountain Mining Venture) Riverton, Wyoming <br />Water, Waste & Land, Inc, implemented a baseline monitoring program designed <br />to fulfill requirements of the Wyoming Department of Environmental Quality. Components <br />of the monitoring program included the collection of surface water quality samples at 21 <br />locations, flow and field parameter measurements, erosion transect measurements, <br />installation and ongoing maintenance of automated sampling equipment, measurements <br />of water levels from wells and piezometers, and installation and maintenance of a <br />meteorological station. A Sampling and Analysis Plan was developed by WWL that <br />included the implementation of a QA(QC program. WWL has been responsible for data <br />validation management and reporting. <br />Remedial Investigations (Asarco, Inc.) Leadville, Colorado <br />Water, Waste & Land, Inc. was responsible for collection of all field date associated <br />with the surface water, tailings, mine waste, and hydrogeology aspects of the Site <br />Investigation being performed as part of the Phase II activities at the California Gulch <br />CERCLA site. Surface water monitoring included collection of samples fqr laboratory <br />analyses of metals, inorganics, and cyanide as well as those used in toxicology studies <br />performed by others, Surface water samples were collected at numerous sites during <br />several sampling episodes. Rigid Quality Assurance/Quality Control procedures were <br />followed during the collection of the samples. WWL personnel also supervisdd all drilling <br />activities associated with investigation of tailings and mine waste disposal ajeas. Work <br />included collection of subsurface samples for chemical as well as geotechnicel laboratory <br />analyses. Selected borings were completed as ground water monitoring wells iwhich were <br />tested to allow hydraulic properties to be estimated. Water quality samples were also <br />collected from these wells. Installation of monitoring wells to allow backgrbund water <br />hydrogeologic conditions to be assessed was also supervised by WWL. Continued <br />collection of water quality samples from these wells occurs on a regular basis. <br />
