Recreational Water Safety Guideline Values
In 2003, the WHO updated the “Guidelines for Safe Recreational Water Environments, Volume 1, Coastal and Fresh Waters”1 to include risk management procedures in addition to the derivation of guideline values.
Chapter 4 on the ‘Microbial Quality of Recreational Water’ addresses the assessment and management of risk based on microbial and sanitary inspection classifications. Whereas the microbial water assessment provides a quantitative indication of the quality at a particular point in time, the sanitary inspection provides an indication of the likelihood of the occurrence of a particular water quality. Combining the classification (based on sanitary inspection and microbial quality assessment) with the prevention of exposure at times of increased risk leads to a framework for managing recreational water quality.
The quantifying of the risk comprises of:
