Regulation 2
“Coastal water” means surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured M1, extending where appropriate up to the outer limit of transitional waters.
“Groundwater” means all water which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil.
“Inland water” means all standing or flowing water on the surface of the land, and all groundwater on the landward side of the baseline from which the breadth of territorial waters is measured.
“Lake” means a body of standing inland surface water.
“River” means a body of inland water flowing for the most part on the surface of the land but which may flow underground for part of its course.
“Surface water” means inland waters, except groundwater; transitional waters and coastal waters, except in respect of chemical status for which it shall also include territorial waters.
“Transitional waters” are bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but which are substantially influenced by freshwater flows.

(b)take samples at every bathing water no later than four days after the date specified in the monitoring calendar.
(2) In relation to any abnormal situation, the appropriate agency—
(a)may suspend the monitoring calendar for the duration of the situation; and
(b)as soon as possible after the end of the situation, must take sufficient additional samples to replace those missing due to the suspension and to ensure that it has the minimum number required for the bathing water for the bathing season.
3. The appropriate agency must—
(a)take and analyse the first sample for every bathing season shortly before the start of that season; and
(b)take and analyse samples at intervals not exceeding one month, from every bathing water throughout the bathing water season.
4.—(1) Subject to paragraph 7, the appropriate agency must only use sampling bottles which—
(a)have been—
(i)sterilised in an autoclave for at least 15 minutes at 121 degrees Celsius;
(ii)dry sterilised at no lower than 160 degrees Celsius and no higher than 170 degrees Celsius for at least one hour; or
(iii)irradiated by their manufacturer and not used previously;
(b)are of a size which allows sufficient water to be taken and analysed for the presence of intestinal enterococci and Escherichia coli; and
(c)are made of transparent and colourless material.
(2) The appropriate agency must—
(a)use aseptic techniques to maintain the sterility of the sample bottles; and
(b)clearly identify every sample taken by marking in indelible ink the sample bottle and associated paperwork.
5.—(1) Subject to paragraph 7, the appropriate agency must—
(a)at all times, protect every sample taken from exposure to light, and in particular, direct sunlight; and
(b)conserve every sample at a temperature of around 4 degrees Celsius between sampling and laboratory analysis.
(2) In relation to any sample, if the interval between sampling and laboratory analysis is likely to exceed four hours, the appropriate agency must conserve the sample in a refrigerator.
(3) The appropriate agency must ensure that the time between sampling and laboratory analysis does not exceed 24 hours and must use its best endeavours to keep this time as short as possible.
6.—(1) Subject to paragraph 7, the appropriate agency must use the following reference methods of analysis—
(a)for intestinal enterococci, one of the following standards of the International Organization for Standardization—
(i)ISO 7899-1:1998 (water quality, detection and enumeration of intestinal enterococci, Part 1, miniaturized method, most probable number, for surface and waste water) as amended by Cor 1:2000, or
(ii)ISO 7899-2:2000 (water quality, detection and enumeration of intestinal enterococci, Part 2, membrane filtration method); and
(b)for Escherichia coli, one of the following standards of the International Organization for Standardization—
(i)ISO 9308-1:2000 (water quality, detection and enumeration of Escherichia coli and coliform bacteria, Part 1, membrane filtration method) as amended by Cor 1:2007, or
(ii)ISO 9308-3:1998 (water quality, detection and enumeration of Escherichia coli and coliform bacteria, Part 3, miniaturized method, most probable number, for the detection and enumeration of E. coli in surface and waste water) as amended by Cor 1:2000.
7. The appropriate agency—
(a)must have regard to the guidelines on the handling of samples for microbiological analyses given in Annex V to the Bathing Water Directive; and
(b)may use such rules or reference methods of analysis as it considers are substantively equivalent to those specified in this Schedule, where the appropriate agency has notified the appropriate Minister giving details of such rules and methods and their equivalence.
8. Where any bathing water profile indicates a potential for cyanobacterial proliferation, the appropriate agency must undertake appropriate monitoring at the bathing water at the frequency necessary to allow adequate management measures to be put in place in accordance with regulation 12.U.K.
9. Where any bathing water profile indicates a tendency for proliferation of macro-algae or marine phytoplankton, the appropriate agency must undertake investigations at the bathing water to allow adequate management measures to be put in place in accordance with regulation 12.U.K.
10. The appropriate agency must undertake visual inspections at every bathing water at the frequency necessary to allow adequate management measures to be put in place in accordance with regulation 12.U.K.
Regulation 11
1. The appropriate agency must use the following standards for classification—
1 Colony forming units per 100 millilitres (“cfu/100 ml”). | |||
2 Based upon a 95-percentile evaluation-see paragraph 2. | |||
3 Based upon a 90-percentile evaluation-see paragraph 2. | |||
Parameter | “Excellent” | “Good” | “Sufficient” |
---|---|---|---|
Intestinal enterococci1 | 2002 | 4002 | 3303 |
Escherichia coli (1) | 5002 | 1,0002 | 9003 |
1 Colony forming units per 100 millilitres (“cfu/100 ml”). | |||
2 Based upon a 95-percentile evaluation-see paragraph 2. | |||
3 Based upon a 90-percentile evaluation-see paragraph 2. | |||
Parameter | “Excellent” | “Good” | “Sufficient” |
---|---|---|---|
Intestinal enterococci1 | 1002 | 2002 | 1853 |
Escherichia coli 1 | 2502 | 5002 | 5003 |
2.—(1) In this Schedule, “percentile value” is based on a percentile evaluation of the log10 normal probability density function of microbiological data used for the assessment under regulation 10.
(2) The appropriate agency must derive a percentile value as follows—
(a)take the log10 value of all bacterial concentrations in the data sequence to be evaluated or, if a zero value is obtained, take the log10 value of the minimum detection limit of the analytical method used;
(b)calculate the arithmetic mean (“�”) of the log10 values taken under paragraph (a);
(c)calculate the standard deviation (“�?”) of the log10 values taken under paragraph (a);
(d)derive the upper 90-percentile point of the data probability density function from the following equation: upper 90-percentile = antilog (� + 1.282 �?); and
(e)derive the upper 95-percentile point of the data probability density function from the following equation: upper 95-percentile = antilog (� + 1.65 �?).
3.—(1) At the end of every bathing season, the appropriate agency must classify a bathing water as “poor” if, in the set of bathing water quality data used, the percentile values for microbiological concentrations are higher than the “sufficient” standards set out in paragraph 1.
(2) At the end of every bathing season, the appropriate agency must classify a bathing water as “sufficient” if—
(a)in the set of bathing water quality data, the percentile values for microbiological concentrations are equal to or lower than the “sufficient” standards set out in paragraph 1; and
(b)the bathing water is not classifiable as “good” or “excellent”.
(3) At the end of every bathing season, the appropriate agency must classify a bathing water as “good” if—
(a)in the set of bathing water quality data, the percentile values for microbiological concentrations are equal to or lower than the “good” standards set out in paragraph 1; and
(b)the bathing water is not classifiable as “excellent”.
(4) At the end of every bathing season, the appropriate agency must classify a bathing water as “excellent” if, in the set of bathing water quality data used, the percentile values for microbiological concentrations are equal to or lower than the “excellent” standards set out in paragraph 1.
