(a) Chemical Quality of Water. Chemical quality of water shall, at all times, be such that there is not irritation of eyes or skin of the bathers, nor other objectionable physiological effects on bathers. Water in the WCR shall have a pH of not less than six point eight or more than eight point four;
(b) Microbiological Quality. WCRR waters shall be routinely sampled and analyzed, at the operator’s expense, for microbiological contamination. Samples shall be collected at a frequency, and from representative locations, as determined by the DEHS. The fecal coliform density from any consecutive sets of samples collected within any 30 days shall not exceed an arithmetic mean of 200 organisms per 100 ml. When fecal coliform density of any sample collected exceeds 1,000 per 100 ml., the DEHS shall order the closure of the water contact area and follow-up daily sampling shall be immediately commenced with waters analyzed for fecal coliform for at least two consecutive days. If any follow-up daily sample exceeds 1,000 per 100 ml., the water contact area shall remain closed, with the appropriate signs posted and maintained by the owner/operator, and shall not reopen without prior written approval being obtained from the DEHS. Periodic sampling for specific pathogens shall be required if ordered by the Health Officer. WCRR which utilize an approved filtration and disinfection system may, upon approval by the DEHS, maintain a daily log of disinfectant and pH test readings in lieu of microbiological sampling. Fecal coliform sampling shall be conducted prior to the commencement of each season’s use and as requested by the DEHS. Routine water samples shall be obtained from representative portions of the swim area at a depth of two feet. Microbiological analysis shall be made in accordance with procedures recommended by the latest edition of the “Standard Methods for Examination of Water and Sewage” of the American Public Health Association.
