Our laboratories perform work under multiple federal and <br />state certification programs and national accreditation programs. <br />Air Quality Testing: <br />CAS provides air quality testing and industrial hygiene services for a wide range of <br />clients and industries through its dedicated Air Quality laboratory. The lab is accredited <br />by the American Industrial Hygiene Association (AIHA) for the analysis of organic <br />compounds and participates in the quarterly Proficiency Analytical Testing (PAT) <br />program administered by the ANA. <br />The Air Quality laboratory specializes in the analysis of volatile and semi -volatile <br />compounds in samples such as ambient air, landfill gas, soil gas, industrial source <br />emissions, odor analyses and indoor air quality investigations. This facility analyzes <br />whole air samples, as well as those requiring solvent or thermal desorption. Other <br />services available include material emission/off-gassing studies and product <br />evaluations. The laboratory has a 1000 -cubic foot testing room and one -liter simulated <br />environmental chambers available for product testing. Recent projects have included <br />evaluations of the performance of residential air purifiers, monitoring of workplace <br />exposures and IAQ/odor evaluations. <br />CERCLA and Remedial Investigation and Feasibility Studies (RIFS)• <br />Since 1986, CAS has performed chemical analyses in support of remedial investigation <br />and feasibility studies (RI/FS), risk assessment, natural resource damage <br />assessments, remedial activities for Superfund sites and related programs. Many of <br />these programs have required CLP methodologies and deliverables for both organic <br />and inorganic parameters on large numbers of air, water, soil and sediment samples. <br />Analytical parameters have included a wide spectrum of methodologies. In some <br />cases, standard operating procedures were written as part of the quality assurance <br />project plan, which outlines project organization and responsibilities, data quality and <br />sample management objectives, stringent quality control, and performance and system <br />audit procedures. CAS has developed special protocols for analytical, quality control, <br />and sampling procedures for specialized methodology of non -routine matrices needed <br />to support project goals. CAS can complement the site project team by participating <br />early in the planning stages and by providing technical advice to all involved including <br />the consultants, potentially liable parties, and governing agencies. <br />Page 23 of 29 <br />
