Regulating Agency:

The regulating agency has primary responsibility to provide oversight and help to the water system.

Water System Classification Types:

Source Type/Primary Source:

Facility Types:

Type of Filtration:
Sampling Groups for Chems:

Chemical Detects:
These are detections of chemicals above a certain threshold (anything greater than 0 for the SOC and VOC groups, greater than half the MCL for the IOC group). That there was a single detect does not mean that a problem exists -- some reasons for single 'hits' include the use of solvents in the area (WD40 for example), gasoline operated machines, deodorant blocs/devices in restrooms, or painting in the vicinity while collecting the sample. The tests for the SOC and VOC groups are very sensitive and can have a detection from something wafting in the air. All chemical detects should be followed up with at least another test.

Coliform Bacteria:

Coliform bacteria are indicator bacteria that are used in testing drinking water. These organisms are found everywhere in nature but when found in drinking water usually means that something has happened to the water system. There are two main types of coliform bacteria - Total and Fecal. Total coliform when found in drinking water can cause intestinal distress and upset in people but rarely anything dangerous. Fecal coliform are associated with sewage or animal wastes and indicate that a serious breakdown in treatment or that contamination has occurred and immediate action is required of the water system to correct the problem.

Type of samples:

Lead and Copper
Maximum Contaminant Level (MCL):

The highest level of a contaminant that EPA allows in drinking water. MCLs ensure that drinking water does not pose either a short-term or long-term health risk. A number of chemicals that are tested for are 'unregulated' and do not have a maximum level set. Usually shown at mg/l -- milligrams per liter.


Violations tend to fall into three main types -- monitoring violation (failed to report test results or failed to do the test); exceed the MCL for a contaminant; or failure to properly treat surface water (treatment technique violation). All the different violatons are listed below.

The Date of the violation is the first day of the month the violation occurred in. If the violation is for a quarter then the date is the first day of the last month of the quarter -- March 1 for the January, February, March quarter; June 1 for April, May, June quarter; September 1 for July, August, September quarter, and December 1 for October, November, December quarter.

Federal Enforcement Codes Used by Oregon:
