Notes:
1 - Fluoride is added to water to help in the prevention of dental cavities (caries) in children.
2 - Of the 50 sites tested, none exceeded the action level. The next round of testing is due in 2008.
3 - Of the 50 sites tested, none exceeded the action level. The next round of testing is due in 2008.

Ideal Goal (MCLG) 0
Level Detected 42.7
Range 12.8 - 69.4 *1
Likely Source By-products of drinking water disinfection.
Violation No
   
Total Haloacetic Acids (THAA'S)

Unit ppb
Highest Level Allowed (MCL) 60
Ideal Goal (MCLG) 0
Level Detected 23.5
Range 11.1 - 35.0 *1

Total Organic Carbon (TOC)
Date Tested 07/03/2007
Unit ppm
Highest Level Allowed (MCL) n/a
Ideal Goal (MCLG) n/a
Amount Detected 2.2
Range 1.0 - 2.2

Chlorite
Date Tested 10/01/2007
Unit ppm
Highest Level Allowed (MCL) 1.0
Ideal Goal (MCLG) 0.8
Level Detected 0.49
Range 0.065 -0.49
Likely Source By-product of drinking water disinifection
Violation No
   
Chlorine (free)
Date Tested 07/11/2007
Unit ppm
Highest Level Allowed (MCL) MRDL = 4
Ideal Goal (MCLG) MRDLG = 4
Level Detected 1.95
Range BDL*2 - 1.95
Likely Source By-product of drinking water disinifection
Violation No
   
Notes:
1 - This contaminant is regulated by the average concentration over a period of a year.
2 - Detection Limit for chlorine is 0.05 mg/L. Disinfection was confirmed by heterotrophic plate count. This is a method that measures total bacteria in a sample. The result was within acceptable limits.

Notes:
1) - 1 positive sample out of 223 samples tested during the month.
2) - 1 positive sample out of 223 samples tested during the month.
3) - 3 positive samples out of 229 samples tested during the month.
4) - 2 positive samples out of 226 samples tested during the month.
5) - 1 positive sample out of 223 samples tested during the month.

Turbidity

Turbidity * 1
Date Tested 05/24/2007
Unit NTU
Highest Level Allowed (MCL) TT=1 NTU/
TT=percentage of samples <0.3 NTU
Ideal Goal (MCLG) 0
Level Detected 0.28 NTU / 100%
Range n/a / n/a
Likely Source Soil Runoff
Violation No
   
Notes:
1 - Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfectants.
