Search Results Help - Drinking Water

Drinking water data displayed on ECHO are not real-time data. Violation and enforcement data are reported quarterly to the data system of record no later than the quarter following the quarter in which the events occur. Water systems, states and EPA use this additional quarter to verify that the data they are reporting are accurate and complete. Some states have more recent data available on their websites. Questions about current drinking water quality in your community can be answered by your local public water system.

As described in detail on the primary Search Results Help home page, the Search Results page presents results that meet the search criteria specified. Information and data specific to the Drinking Water facility search is described below, including:

Results Guide

The search results present data from EPA's Safe Drinking Water Information System. Read About the Data for more information on each data source and when the data were last updated in ECHO.

Note: Data about violations in each calendar quarter becomes available in the national data system (SDWIS) after the end of the following quarter. Water systems, states, and EPA use this additional three-month verification period to check the reported violation data for accuracy and completeness. The data then become available in ECHO some time after that. For example, data about violations entered by September 30 in a given year will become final in SDWIS on December 31, and become available in ECHO in January or later. The date of the latest SDWIS data available in ECHO is shown on the About the Data page, and in the "Current As Of" field of the Detailed Facility Report. Some states have more recent data available directly on their websites.

Data fields included in the search results are described below. The results page field name is listed in bold and the data download file field name is listed [within brackets in italics].

System Type [PWSTypeCode, PWSTypeDesc]
The type of public water system (PWS). A public water system is a system for the provision to the public of piped water for human consumption, which has at least 15 service connections or regularly serves an average of at least 25 individuals at least 60 days out of the year.
  • Community water system (CWS) - A PWS that serves at least fifteen service connections used by year-round residents or regularly serves at least 25 year-round residents (e.g., homes, apartments and condominiums that are occupied year-round as primary residences).
  • Non-community water system (NCWS)
  • Transient non-community water system (TNCWS) - A non-community water system that does not regularly serve at least 25 of the same persons over six months per year   A typical example is a campground or a highway rest stop that has its own water source, such as a drinking water well.
  • Non-transient non-community water system (NTNCWS) - A non-community PWS that regularly serves at least 25 of the same persons over six months per year. A typical example of a non-transient non-community water system is a school or an office building that has its own water source, such as a drinking water well.
Source Water Type [PrimarySourceCode, PrimarySourceDesc]
The source water type:
  • Surface water (SW) - Water pumped and treated from sources open to the atmosphere, such as rivers, lakes, and reservoirs.

Compliance Status

Important Note:  All compliance and enforcement data displayed on ECHO are current as of the last quarterly refresh.

Quarters in Violation (3 yrs) [QtrsInVio]
The number of quarters the system was in violation over the past three years. This includes the 12 most recent official quarters and new violations reported after the end of the last official quarter.
Quarters as a Serious Violator (3 yrs) [QtrsInSNC]
The number of quarters the system was designated by EPA as a serious violator over the past 3 years (12 most recent quarters).
Serious Violator [SeriousViolator]
'Yes' indicates a public water system with unresolved serious, multiple, and/or continuing violations that is designated as a priority candidate for formal enforcement, as directed by EPA's Drinking Water Enforcement Response Policy (PDF)(16 pp, 952 K, About PDF).
EPA designates systems as serious violators so that the drinking water system and primacy agency will act quickly to resolve the most significant noncompliance. Many public water systems with violations, however, are not serious violators. Operators and the primacy agencies are expected to correct the violations at non-serious violators as well, but without the more strict requirements and deadlines applicable to serious violators. If the violations at a non-serious violator are left uncorrected, that system may become a serious violator. When a serious violator has received formal enforcement action or has returned to compliance, it is no longer designated a serious violator. EPA updates its serious violator list on a quarterly basis.
Health-Based Violations [HealthFlag]
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.
Monitoring and Reporting Violations [MrFlag]
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.
Public Notice Violations [PnFlag]
Violations of the public notification requirements of SDWA, which require systems to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
Other Violations [OtherFlag]
Violations of other requirements of SDWA, such as issuing annual consumer confidence reports or maintaining required records.
Has New Violations [NewVioFlg]
Violations that have been reported to SDWA since end of the last official quarter. These violations are considered draft and do not reflect the official compliance status for the facility.
Rules in Violation (3 Years) [RulesVio3yr]
The count of rules the system was in violation of over the past three years. This includes the 12 most recent official quarters and new violations reported after the end of the last official quarter.
Rules Currently being Violated [RulesVioCurr]
The count of rules the system is currently violating. This includes violations in the most recent official quarter and new violations reported after the end of the last official quarter.

Compliance Points

EPA uses a weighted point system that reflects the degree of noncompliance at each public water system; generally more points means more violations of a serious nature. The point system allows primacy agencies – usually states – to rank public water systems in order of severity of noncompliance, so that those with more serious noncompliance can receive appropriate responses, including formal enforcement action.

Points for violations are assigned as in the following examples:

Points Description
10 points
  • Acute contaminant maximum contaminant level (MCL) violation (total coliform or nitrate)
5 points
  • MCL or treatment technique violation for regulated contaminants other than total coliform or nitrate
  • Nitrate monitoring and reporting violation
  • Total coliform repeat monitoring violation
1 point
  • Monitoring and reporting violation not listed above
  • Public notice violation
  • Consumer Confidence Report violation
  • Additional point for each year a violation is unaddressed
Violation Points Accrued (5 years) [viopaccr]
Sum of all violation points for violations reported during the past five years (20 most recent quarters), as of the last quarterly refresh.
Remaining Uncorrected Violation Points (current) [vioremain]
Sum of violation points that were not returned to compliance as of the last quarterly refresh.  Includes points that have received formal enforcement but have not returned to compliance.
Violation Points under Formal Enforcement, but Not Yet Corrected (5 years) [viofeanot]
Sum of violation points accrued during past five years (20 most recent quarters) that are under formal enforcement but not yet returned to compliance, as of the last quarterly refresh.
Violation Points Returned to Compliance by Formal Enforcement (5 years) [viortcfea]
Sum of violation points during past 5 years (20 most recent quarters) that received formal enforcement and returned to compliance, as of the last quarterly refresh.
