The tables below list all violations that the state reported to EPA for this water system. Health-based violations are listed first, followed by treatment technique, MRDL, monitoring, reporting, and other violations.

Health-based	Violations of maximum contaminant levels (MCLs) or maximum residual disinfectant levels (MRDLs), which specify the highest concentrations of contaminants or disinfectants, respectively, allowed in drinking water; or of treatment technique (TT) rules, which specify required processes intended to reduce the amounts of contaminants in drinking water. MCLs, MRDLs, and treatment technique rules are all health-based drinking water standards.
Maximum Contaminant Level or MCL	The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
Treatment Technique	A required process intended to reduce the level of a contaminant in drinking water.
Maximum residual disinfectant level or MRDL	The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Monitoring & reporting	Failure to conduct regular monitoring of drinking water quality, as required by SDWA, or to submit monitoring results in a timely fashion to the primacy agency or EPA.
Public notification & other	Failure to provide notification to the public as required by the Violations of Public Notification Rule and the Consumer Confidence Report Rule, and violations of other requirements such as those violations related to variances and exemptions.

For more information on a Water System:
Ask the operators of your water system, contact your primacy agency or file a Freedom of Information Act (FOIA) request.
Drinking water in general: Find out more about your drinking water web site or call the Safe Drinking Water Hotline (1-800-426-4791). EPA has also prepared a table about various regulated drinking water contaminants.
Tools for accessing EPA drinking water data: Safe Drinking Water Information System (SDWIS) Federal Reporting Services and Drinking Water Performance and Results Report.
Research Data: As well as monitoring the levels of drinking water contaminants for which EPA has set standards, EPA, states, and water systems also carry out studies of contaminants that may need to be regulated in the future. For more information about these contaminants, please see the National Contaminant Occurrence Database.
