Specialty Testing In addition to our routine analytical capabilities, CT Laboratories LLC offers specialty testing services and can help develop new procedures to suit your needs. These analyses support various environmental regulatory programs, including: Resource Conservation and Recovery Act (RCRA) Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Superfund Clean Water Act (CWA) National Pollution Discharge Elimination System (NPDES) Safe Drinking Water Act (SDWA) Federal Program Support: Army Corps, National Guard, Coast Guard, Navy, Air Force Various State Regulatory Programs: Underground Storage Tank (UST), Landfill Monitoring, etc. Total, Fine and Coarse Lead by MDEQ SOP 213 This procedure is typically performed for EPA projects in order to characterize the lead fractionation of the soil (i.e., the fine & coarse fractions). The Michigan Lead procedure involves sieving an air-dried soil sample into the coarse fraction (particle size > 250-µm) and the fine fraction (particle size < 250-µm). The % coarse and % fine values are determined via calculation. The coarse and fine fractions are then analyzed for lead via EPA 6010C. Finally, the total lead concentration is calculated via a weighted average of the coarse lead fraction and the fine lead fraction. Tissue Analysis: Pesticides, PCBs, Metals, Percent Lipids These internal methods are not certified by our accreditation agencies. These internal methods have been developed to fulfill client-specific needs and projects. Thiodiglycol and other Chemical Warfare Agent degradation products This method is designed to follow procedures developed in-house and to meet the requirements of EPA SW-846 method 8000 for ground water, surface water, and waste water. A UPLC is employed in conjunction with a UV detector.
