Connecticut DEEP Reasonable Confidence Protocols

Connecticut Department of Energy and Environmental Protection (CT DEEP) has been working to improve the quality and consistency of analytical data used to support environmental investigation and remediation projects statewide. This work has included the introduction of the CT DEEP Reasonable Confidence Protocols (RCPs) developed with assistance from the CT DEEP Quality Assurance/Quality Control Work Group established in 2004.  The CT DEEP Work Group is composed of licensed environmental professionals, data validators, and representatives from private laboratories, the Connecticut Department of Public Health (CT DPH), the U.S. Environmental Protection Agency (USEPA), and the CT DEEP.  Alpha Analytical has participated in the CT DEEP Work Group since its inception. 

Alpha Analytical provides analytical support in accordance with the CT DEEP Reasonable Confidence Protocols (RCP) for a range of analytical parameters including: 

  • Volatile Organics by Method 8260
  • Semi volatile Organics by Method 8270
  • Organochlorine Pesticides by Method 8081
  • PCB aroclors by Method 8082
  • Chlorinated Herbicides by Method 8151
  • Volatile Petroleum Hydrocarbons (VPH) by the MassDEP VPH Method 
  • Extractable Petroleum Hydrocarbons (EPH) by the MassDEP EPH Method
  • Air-Phase Petroleum Hydrocarbons (APH) by the MassDEP APH Method
  • Volatile Organics in Air by Method TO-15
  • PAHs in Air by Method TO-13
  • RCP Metals by Methods 6010 & 6020
  • Total Mercury by Methods 7470 & 7471 
  • Hexavalent Chromium by Method 7196 
  • Total Cyanide by Methods 9010 & 9012  
  • TCLP and SPLP sample preparation by Methods 1311 and 1312

Alpha Analytical provides analysis of the RCP-listed target compounds associated with the analytical methods listed above. Alpha Analytical provides a complete CT DEEP RCP compliant laboratory report with the results and a supporting summary of quality control information. A full data package including raw data is also available upon request. Results are reported routinely to the reporting limit (RL), which is derived based on the concentration of the lowest calibration standard, as proscribed in the CT DEEP RCP. For increased sensitivity, results can be reported to the method detection limit (MDL) with a J flag. Alpha Analytical offers a wide range of Electronic Data Deliverables (EDD) formats.

Alpha Analytical is a state of Connecticut Department of Public Heath (CT DPH) approved laboratory and we are accredited by the National Environmental Laboratory Accreditation Program (NELAP) for a full range of analytical methods applicable to groundwater, surface water, soil, sediment, tissue, dredged material, waste, and vapor intrusion samples.
