Our laboratories perform work under multiple federal and i <br /> istate certification programs and national accreditation programs. i <br /> Air Qualms Testing_ <br /> I <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 1 <br /> compounds and participates in the quarterly Proficiency Analytical Testing (PAT) <br /> program administered by the AIHA. j <br /> r <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 lAQ/odor evaluations. <br /> CERCLA and Remedial Investigation and Feasibility Studies(R/FS): <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 i <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 I <br /> the consultants, potentially liable parties, and governing agencies. <br /> i <br /> Page 23 of 29 <br />
