What's in our drinking water
Listed below is information on contaminants that were found in the City of Fairfield’s drinking water in 2005, the most recent year for what data is available. Data is the result of monitoring required by EPA, some of which is not required to be monitored each year. Samples were collected in the distribution system and at plant taps as required by EPA. 2005 daily averages for the Lime Treatment Process are as follows:
pH (S.U.) 8.5
Hardness (ppm) 132
Chlorine (ppm) 1.17
Phosphate (ppm) 0.12

ND Below analytic method detection level.
Because accurate test methods for detecting Cryptosporidium at very low levels are not available, the EPA does not require testing of treated drinking water unless their concentration in the raw water exceeds 10 per liter. The city was not required to monitor for Cryptosporidium.
