2017 Water Sampling

During the past year the FTDWD staff has taken thousands of water samples in order to determine the presence of any biological, inorganic, volatile organic or synthetic organic contaminants. These samples were taken at the reservoirs, the treatment plant, and the well field and also at representative sample sites around the distribution system. The table below shows only those regulated substances that were detected in the treated water. All of the substances found meet all state and federal standards. The most recent year sampled is noted in the table.

1 - Amount detected; ranges are monthly averages.

2 - There is no federal MCL for sodium but Connecticut has established a notification level of 28 mg/L. If you have been placed on a sodium-restricted diet please inform your physician of the sodium content in our water. For people on a regular diet this level of sodium is very low.

3 - Turbidity is a measure of the clarity of the water. It is monitored because it is a good indicator of the effectiveness of the filtration system. 95% of the samples need to be less than 0.3 NTU. The District met the regulation requirements 100% of the time. Amount is an average of the highest monthly readings.

4 - The District’s water met the required removal rate 100% of the time.

5 - Amount is that of the highest annual average of quarterly measurements in the distribution system and the range are results of the individual sites.

6 - Tap water samples were collected for lead and copper analyses from over 60 homes throughout the service area in both the spring and fall. The lead and copper results at the 90th percentile did not exceed the AL (listed in table under Distributions System). A lead sample from one home had a result that exceeded the AL, after cleaning the faucet screen, the resample was non-detect.

7 - Unregulated Contaminant Monitoring Rule (UCMR) 3 monitoring was done in 2013. There is a list of 10 selected contaminants which do not yet have a drinking water standard set by the EPA. The purpose of the monitoring is to help the EPA decide whether the contaminants should have a standard. We detected five of these contaminants in either our surface or groundwater supplies and distribution system.
