External Quality Assessment for Water Microbiology Laboratories
This program offers samples for proficiency testing of laboratories involved in the microbiology testing of Drinking and Recreational waters.
CMPT OFFERS FIVE WATER MICROBIOLOGY EQA PROGRAMS
for laboratories testing drinking water for the presence of fecal coliforms.
for laboratories performing detection of heterotrophic count (HPC) of organisms in drinking water samples.
for laboratories testing recreational (beach and pool) waters for the presence of potential pathogens.
for laboratories testing marine beach sediment for the presence of Enterococcus species.
for laboratories testing soil for the presence of Salmonella species.
Challenges are directed towards detection, enumeration and identification of water safety indicator organisms.
Drinking and HPC Water: Three shipments per year: April, July, and October.
Recreational Water: two shipments per year: April and August
Sediment Water: two shipments per year: April and October
Soil: two shipments per year: April and October
Drinking Water: 4 samples for processing per shipment.
HPC Water: 4 samples for processing per shipment.
Recreational Water: 3 samples for processing per shipment.
Sediment Water: 10 samples for processing per shipment.
Soil: 2 samples for processing per shipment
Samples are simulated stabilized water that can be assessed by membrane filtration, MPN, or other assays.
