NOTICE OF REPORT SUMMARY AND FULL REPORT AVAILABILITY 1999 PUBLIC WATER SYSTEMS VIOLATIONS REPORT CONNECTICUT DEPARTMENT OF PUBLIC HEALTH WATER SUPPLIES SECTION

The Department of Public Health (DPH) is Connecticut's lead State agency in all matters related to the purity and adequacy of drinking water. The Water Supplies Section (WSS) in the Department's Bureau of Regulatory Services administers the Federal Safe Drinking Water Act (SDWA) at the State level. The Section's responsibilities for the SDWA include regulating over 4,600 public water systems throughout Connecticut.

In 1996, the United States Congress amended the SDWA. One of the most important provisions in the amendments was a public information component that requires State drinking water programs to provide the public with a summary of public water system violations on an annual basis.

During 1999 maximum contaminant level (MCL) violations were issued to 44 community public water systems and 86 non-community public water systems. Two hundred thirty-three of the total 25S MCL violations were for total coliform bacteria of which 27 were for E. coli bacteria (total coliform (acute)).

Twenty-two MCL violations involve the following contaminants tetrachloroethylene (6), 1,2 Dichloroethane (1), nitrate (8), arsenic (4), gross alpha (1) and radium 226 & 228 (2). Thirty-five of the community public water systems and 73 of the non-community public water systems have now returned to compliance. Appropriate public health measures have been implemented at the remaining systems.

Nine community and twenty-five non-transient non-community public water system incurred treatment technique violations under the Surface Water Treatment Rule (SWTR) and the Lead and Copper Rule (LCR). The 3 systems that incurred violations under the SWTR are on a schedule to achieve compliance. Two community public water systems failed to install corrosion control treatment and four failed to complete public education under the LCR. Four of the community public water systems have since achieved compliance. Twenty‑five non transient non‑community public water systems failed to complete public education under the LCR. Twenty of the systems have since returned to compliance.

The WSS issued monitoring and reporting violations to 27 community public water systems and 104 non-community public water systems. These violations are for regulated contaminants such as total coliform bacteria, nitrate and volatile organic chemicals (VOCs). Each contaminant in a group represents a separate violation, therefore if a system failed to submit test results for VOCs this resulted in 21 separate violations.
