Universal Citation: LA Admin Code V-1309

Current through Register Vol. 50, No. 9, September 20, 2024

A. If a water supply system has a single fluoridation system which treats all the water distributed to system consumers, the supplier shall collect a daily water sample for fluoride analysis either in the distribution system or at the entry point. If a water supply system does not fluoridate all its water and/or has more than one fluoridation system, the supplier shall collect a minimum of one water sample daily in the distribution system and shall rotate the sample site daily in order to obtain representative results of the level of fluoride in the water provided throughout the distribution system. If the water supply system is such that a single daily sample taken in different locations cannot provide a representative level, then multiple samples may be required. The number, location, and frequency of samples shall be in accordance with a monitoring plan developed by the water supply system and approved by the DHH-OPH.

1. If more than 20 percent of the daily fluoride samples collected in a month by a water supply system fall outside the optimal fluoride level/range, the system shall be out of compliance with the optimal fluoride level/range.

2. At least once a month, any water supplier with an operating fluoridation system shall divide one sample and have one portion analyzed for fluoride in a "DHH-OPH Approved Chemical Laboratory/ Drinking Water" lab (normally, on-site of the water treatment plant-see LAC 51:XII.Chapter 15) and the other portion analyzed for fluoride in a "DHH-OPH Certified Laboratory for Drinking Water Analyses-Chemistry". (A list of such "DHH-OPH Certified Laboratory for Drinking Water Analyses-Chemistry" may be found on the DHH-OPH website at the following url address: "http://www.dhh.louisiana. gov/offices/?ID=204".)

3. Any water supply system with an operating fluoridation system shall sample the raw source water(s) annually and analyze for fluoride.
