Section 335-7-10-.03 - Water Quality Control Tests

In addition to monthly microbiological monitoring and periodic chemical/radiological/TTHM/VOC monitoring, the following control tests shall be performed and recorded at the specified frequency:

(a) At surface water or ground water under the influence of surface water treatment plants serving community and NTNC systems, the following tests shall be performed and recorded during plant operation:

1. Disinfectant residual of the finished water every other hour. Also, those plants serving a population of 3,300 or greater must have continuous recording and indicating disinfectant residual equipment;

2. Carbon dioxide of the raw water once per shift;

3. Color, iron, manganese and total alkalinity of the raw and finished water daily;

4. Fluoride of the raw water weekly and of the finished water daily when the concentration is adjusted;

E. Coli and total coliform bacteria of the raw water source once per month or as required by the Department to evaluate quality of the raw source or treated water. Results must be reported as number of counts per 100 mL of sample;

6. pH of the raw and finished water each shift,

7. Turbidity:

(i) Raw water every other hour,

(ii) Each clarification unit every four hours, and

(iii) Filtered water from each filter every fifteen minutes or on a continuous basis if a recording turbidimeter is used, and

8. Other tests at the frequency required by the Department.

(b) At groundwater treatment facilities serving community and NTNC systems, the following tests shall be performed and recorded at least daily:

1. Free chlorine residual of the finished water representing each source or plant;

2. Fluoride of the finished water if the level is adjusted;

3. Iron of the raw and finished water, when the raw water concentration exceeds 0.3 mg/l;

4. Manganese of the raw and finished water, when the raw water concentration exceeds 0.05 mg/l;

5. pH of the finished water from each source or plant if a chemical is fed to adjust the pH or if the pH is below 7.0;

6. Turbidity of the raw water if directed by the Department or if the turbidity exceeds 5.0 NTU;

7. Other tests at the frequency determined necessary by the Department.

(c) Results of all water quality control tests shall be provided to the Department as specified in the Reports section of this chapter (ADEM Admin. Code 335-7-10-.06).
