Disinfection Efficacy Testing
GAP has extensive experience providing microbial support for UV disinfection validation efforts following USEPA and NWRI protocols. Our laboratory is equipped with a collimated-beam apparatus. This apparatus is used to determine the dose-response of microorganisms to UV light. Our analysts are fully trained to conduct these experiments using accepted industry procedures and standards.

Supply of Microorganisms for Challenge Testing
As well as providing analysis for bioassay samples, GAP provides challenge microorganisms stocks, such as Bacteriophage MS2, Phi-x 174, or T1UV.

Air Quality Analysis and Equipment Supply
GAP EnviroMicrobial Services provides equipment and laboratory analysis for indoor air quality monitoring. We can supply the equipment needed to collect samples, or we can arrange for one of our analysts to conduct the testing.

Pathogen Detection
We analyze samples for the presence of microbial pathogens such as Pseudomonas aeruginosa, Clostridium perfringens, Salmonella, Shigella, Staphylococcus, and Campylobacter. In addition, GAP is accreditated for Legionella testing and provides quantitative L. pneumophila serotype 1, L. pneumophila serotype 2-14 and other Legionella species results using a method that combines culturable, serological and molecular techniques.

Molecular Biology
GAP provides a wide range of molecular analysis, including microbial source tracking using fingerprint analysis and RealTime PCR.
