EEC Directive 76/160 (1976) specifies a minimum requirement of one sample every 15 days, but higher sampling frequencies are useful, especially where tidal currents induce rapid variations in quality. In such situations, a high sampling frequency is better than a large number of sampling points. Recreational water sample collection It is important to ensure that samples do not become contaminated at the time of collection or before they are analysed. The basic procedure for collecting a sample is to hold the bottle near its base, to place it below the surface of the water and to remove the cap so that it can be filled with water at the desired depth.

2. Validation Validation should be regarded as the basis for assessing the effectiveness and reproducibility of the sterilization process. Initial validation (start-up validation) is undertaken when the product sterilizer/ process combination is tested for the first time. Revalidation is necessary after work is done on the sterilizer or peripheral equipment that influences the process. Revalidation may also be necessary when deviations are noted within the course of the process that fall outside the tolerances.
