Drinking/Process Water Sampling & Analysis

The presence of bacteria and pathogenic (disease-causing) organisms is a concern when considering the safety of drinking water or water used in the preparation of foods. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses. Bacterial contamination cannot be detected by sight, smell or taste. The only way to determine if a water supply contains bacteria is to test it.
CLS provide a range of microbiological testing services for drinking water, process water and ice to comply with the EC (Drinking Water) (No.2) Regulations 2007.

Our service includes:

  • Pathogen Detection
  • Indicator Bacteria enumeration e.g. Total Coliforms
  • Legionella Risk Assesment/Sampling/Analysis/Control
  • Cryptosporidium Analysis.

Cryptosporidium is a protozoan organism which causes cryptosporidiosis. Cryptosporidium parvum is now recognised as a human pathogen which can cause severe diarrheal illness. Ingestion of drinking water contaminated with viable Cryptosporidium oocysts, the environmentally resistant form of the organism, is the major mode of transmission. Cryptosporidium is introduced into the water supply via animal excreta containing oocysts.
