(*) Based upon a 95-percentile evaluation (1) (**) Based upon a 95-percentile evaluation (1) (1) Based upon percentile evaluation of the log10 normal probability density function of microbiological data acquired from the particular bathing water, the percentile value is derived as follows:

o Take the log10 value of all bacterial enumerations in the data sequence to be evaluated. (If a zero value is obtained, take the log10 value of the minimum detection limit of the analytical method used instead.)
o Calculate the arithmetic mean of the log10 values (μ).
o Calculate the standard deviation of the log10 values (σ).
o The 90-percentile point and 95-percentile point are derived from the following equations:

90-percentile = antilog (μ + 1,282 σ).

95-percentile = antilog (μ + 1,65 σ).

ANNEX II

RULES ON THE HANDLING OF SAMPLES FOR
MICROBIOLOGICAL ANALYSIS

1. Sterilisation of sample bottles: Sample bottles are: - to undergo sterilisation in an autoclave for at least 15 minutes at 121C, or - to undergo dry sterilisation at between 160C and 170C for at least one hour, or - to be irradiated sample containers obtained directly from the manufacturer. 2. Sampling Sampling is performed by using a sample pole and a sterile transparent sampling bottle with a minimum volume of 250 ml. Sample containers are to be of transparent and non-coloured material (glass, polyethene or polypropylene). In order to prevent accidental contamination of the sample, the sampler is to employ an aseptic technique to maintain the sterility of the sample bottles. There is no further need for sterile equipment (such as sterile surgical gloves or sample pole) if this is done properly. The sampling bottle must be clearly labelled in indelible ink. 3. Storage and transport of samples Water samples are to be protected at all stages of transport, from the sampling point to analysis at the laboratory, from exposure to light, in particular direct sunlight, and conserved in a cool box or refrigerator at a temperature of around 4C ? 3C. The time between sampling and analysis is to be kept as short as possible. It is recommended that samples be analysed on the same day. In exceptional cases the samples may be processed within no more than 24 hours. In the meantime, they shall be stored in the dark and at a temperature of 4C ? 3C.
