Section 8:26-7.3 - Sample collection for swimming pools, wading pools, hot tubs, spas, and aquatic recreation facilities
(a) Water samples shall be collected prior to opening for the season and when the swimming pool, wading pool, hot tub, spa, or aquatic recreation facility is in use and during periods of maximum user load. The hour of the day and the day of the week of sample collection shall be varied to obtain, over a period of time, a representative sampling of the sanitary quality of the swimming pool, wading pool, hot tub, spa, or aquatic recreation facility.
(b) Sampling shall be done at least once every week during periods of maximum user load.
1. For swimming pools using disinfection and filtration, sampling may be done biweekly, based upon three months of consecutive satisfactory sample results.
(c) All sample containers shall be sterilized and treated with sodium thiosulfate to reduce chlorine or other halogens present in the water at the time the sample is collected.
(d) The following sampling technique shall be used:
1. The sample shall be taken at least 18 inches below the water surface in the vicinity of groups of bathers. If the water depth is less than 18 inches, the sample shall be taken at one half the level of the water depth in the sampling area. For spray areas, the sample shall be taken at the source of the water;
2. The sterile container shall be opened carefully without touching the inner surfaces;
3. The sterile container shall be held near its base at a 45 degree angle;
4. The sterile container shall be plunged into the water in a forward-sweeping manner while making sure that the dechlorinating agent is not washed out;
5. The container shall be filled with one slow sweep down through the water with the mouth of the container always ahead of the hand.
6. Care shall be taken to avoid contamination of the sample by floating debris;
7. The container shall be closed without touching the inner surfaces; and
8. The container shall not be rinsed.
