Environmental Microbiology Services
Services provide water quality consultation, field reconnaissance and sample collection, and microbiology laboratory analyses. The following analyses are performed on wastewater, recreational water, source and drinking water according to Standard Methods for the Analyses of Water and Wastewater, 20th ed.:
- Total coliform (MTF, MF, Colilert)
- Fecal coliform (MTF, MF)
- E. coli (Colielrt)
- Enterococci (MF, Enterolert)
- Bacteriophage (including assays for MS-2, preparation of concentrated coliphage stocks, UV collimated beam tests for UV system validation)
The goal of CRG Laboratories is to expand EMS in the near future and to include testing for human enteric viruses in environmental samples by tissue culture techniques.
Trace Organics
Trace Organic analytical capability includes leading edge technology and we are experienced at working at extremely low detection limits. Sample extraction is performed with our Microwave Extraction System or by more conventional methods. Using the Microwave Extraction System, non-destructive microwave energy heats samples in a closed system consisting of Teflon vessels, resulting in improved extraction efficiency.
