CALIFORNIA WATER LABO <br /> GUALTTY A5.3t1R"CEIQUALITY CONTROL <br /> MANAGEME 'r 9UM MARY <br /> �GartUnna� <br /> -, Our modern equipment systema include TOC and TOX analyzers,AAs.HPLC,UCP, <br /> Finriigan 5100 GC/MS systems configured with an IBM-PC/AT and Forcmaster <br /> software, and a versatile range of gas chromatographs with 4-channel data systems. <br /> detectors,purge and trap units,headspace analyzes.and other anrillary equipment <br /> to perform specific tasks. <br /> Field Services <br /> Few analytical labs in the United States are as readily prepared to help clients at <br /> the point of origin. CWL has staff specialists to operate its pumping and sampling <br /> equipment and field instrumentation, and provide sample transport The on-site <br /> service is indispensable when EPA requires third-party handling under its supervi- <br /> sion; it also can be more cost-effective for a client than having its own sampling <br /> equipment and know-how at the site in normal circumstances. The CVL field team <br /> is also prepared for emergency sampling when spills or other accidents require quick <br /> Identification of possibly hazardous mater[als. <br /> Consulting <br /> CwL can prepare sampling and analysis plans and evaluate the effectiveness of <br /> cocisting plans for clients seeldng to obtain and maintain monitoring, discharge,and <br /> storage permits. A commonly occurring en-cample is Haat CWL first conducts a <br /> treatability study of a caste stream according to terms of a permit; then it develops <br /> in the lab a prototype of removal/reduction chemistry for the client to apply at hill <br /> scale; and then it samples and analyzes the installed process to confirm regulatory <br /> compliance- Similarly.ML assists landfill operators with the stricter groundwater <br /> sampling/anr.Iysis plans mandated under HCRA. <br /> in this new era of stricter demands for protecting the environment, CWL ofrers <br /> clients not only laboratory and on-site service of the highest quality but also the kind <br /> of technical advice and e.%?ertiset that lends confidence to planning. <br /> QUALITY ASSURANCE <br /> Sample Coilection and Preservallon <br /> guallty assurance begins at the time of samplingand includes protocol reIating to: <br /> ❑ Grab and Composite Sampling <br /> ❑ Sampling for Bacteriological Analysis <br /> ❑ Sampling of Monitoring Wells by Pumping and salting <br /> ❑ Sampling at Underground Storage Tank Sites <br /> T ❑ Physical Field Measurements <br /> ❑ Field Equipment CalfbratJon <br /> ❑ Field Sample Preservation <br /> ❑ Air Sampling <br /> ❑ Field QC Samples <br /> 2 <br />
