TABLE 6 - SAMPLING RESULTS SHOWING TREATMENT OF SURFACE WATER

Treatment Technique - required process intended to reduce the level of contaminants in drinking water: Approved conventional treatment consisting of flocculation, sedimentation, tri-media filtration and disinfection.

Turbidity Performance Standards - turbidity is a measurement of the cloudiness of the water and is a good indicator of water quality and filtration performance. Turbidity results which meet performance standards are considered to be in compliance with filtration requirements.

Turbidity of hte filtered water must:

1. Be less than or eagual to 0.5 NTU in 95% of measurements in a month.

2. Not exceed >1.0 NTU for more than eight consecutive hours.

3. Not exceed 5.0 NTU at any time.

Lowest monthly percentage of samples that met Turbidity Standard No.1 = 100%

Highest single turbidity measurement during the year = 0.9NTU

The number of violations of any surface water treatment requirements = 0

SUMMARY INFORMATION FOR CONTAMINANTS EXCEEDING AN MCL OR AL OR A VIOLATION OF ANY TREATMENT OR MONITORING AND REPORTING REQUIREMENTS: NONE
