State Primary Drinking Water Regulations
							 (SPDWR):
A. Microbiological Contaminants:
1a. Total coliform[Dagger]
Zero
See
							 footnote3
Coliforms are bacteria that are naturally present in
							 the environment and are used as an indicator that other, potentially harmful,
							 bacteria may be present. Coliforms were found in more samples than allowed and
							 this was a warning of potential problems.
1b. Fecal coliform/E. coli[Double
							 Dagger]
Zero
Zero
Fecal coliforms and E. coli are bacteria whose
							 presence indicates that the water may be contaminated with human or animal
							 wastes. Microbes in these wastes can cause short-term effects, such as
							 diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special
							 health risk for infants , young children, some of the elderly, and people with
							 severely compromised immune systems.
1c. Fecal Indicators (Ground Water
							 Rule)
Fecal indicators are microbes whose presence
							 indicates that the water may be contaminated with human or animal wastes.
							 Microbes in these wastes can cause short-term health effects, such as diarrhea,
							 cramps, nausea, headaches, or other symptoms. They may pose a special health
							 risk for infants, young children, some of the elderly, and people with severely
							 compromised
immune systems.

1e. Revised Total Coliform Rule (R.61-58.17) Coliform Assessment
							 and/or Corrective Action Violations[Double Dagger]
N/A
TT
Coliforms are bacteria that are naturally present in
							 the environment and are used as an indicator that other, potentially harmful,
							 waterborne pathogens may be present or that a potential pathway exists through
							 which contamination may enter the drinking water distribution system. We found
							 coliforms indicating the need to look for potential problems in water treatment
							 or distribution. When this occurs, we are required to conduct assessments to
							 identify problems and to correct any problems that are found. [THE SYSTEM MUST
							 USE THE FOLLOWING APPLICABLE SENTENCES.]
We failed to conduct the required assessment.
We failed to correct all identified sanitary defects
							 that were found during the assessment(s).
1f. Revised Total Coliform Rule (R.61-58.17)
E. coli Assessment and/or Corrective Action
							 Violations[Double Dagger]
N/A
E. coli are bacteria whose presence indicates that
							 the water may be contaminated with human or animal wastes. Human pathogens in
							 these waters can cause short-term effects, such as diarrhea, cramps, nausea,
							 headaches, or other symptoms. They may pose a greater health risk for infants,
							 young children, the elderly, and people with severely compromised immune
							 systems. We violated the standard for E. coli, indicating the need to look for
							 potential problems in water treatment or distribution. When this occurs, we are
							 required to conduct a detailed assessment to identify problems and to correct
							 any problems that are found.
[THE SYSTEM MUST USE THE FOLLOWING APPLICABLE
							 SENTENCES.]
We failed to conduct the required assessment.
We failed to correct all identified sanitary defects
							 that were found during the assessment that we conducted.
1g. E. coli[Double Dagger]
Zero
In compliance unless one of the following conditions
							 occurs:
(1) The system has an E. coli-positive repeat sample
							 following a total coliform-positive routine sample.
(2) The system has a total coliform-positive repeat
							 sample following an E. coli-positive routine sample.
(3) The system fails to take all required repeat
							 samples following an E. coli-positive routine sample.
(4) The system fails to test for E. coli when any
							 repeat sample tests positive for total coliform.
E. coli are bacteria who presence indicates that the
							 water may be contaminated with human or animal wastes. Human pathogens in these
							 wastes can cause short-term effects, such as diarrhea, cramps, nausea,
							 headaches, or other symptoms. They may pose a greater health risk for infants,
							 young children, the elderly, and people with severely compromised immune
							 systems.

Add for public notification only:
The chlorine dioxide violations reported today include exceedances of the EPA
							 standard within the distribution system which delivers water to consumers.
							 Violations of the chlorine dioxide standard within the distribution system may
							 harm human health based on short-term exposures. Certain groups, including
							 fetuses, infants, and young children, may be especially susceptible to nervous
							 system effects from excessive chlorine dioxide exposure.

TT
Total organic carbon (TOC) has no health effects .
							 However, total organic carbon provides a medium for the formation of

				unit
6There are various regulations that
				set turbidity standards for different types of systems, including the 1989
				Surface Water Treatment Rule (SWTR), the 1998 Interim Enhanced Surface Water
				Treatment Rule (IESWTR), and the 2001 Long Term 1 Enhanced Surface Water
				Treatment Rule. Systems subject to the Surface Water Treatment Rule (both
				filtered and unfiltered) may not exceed 5 NTU. In addition, in filtered
				systems, 95 percent of samples each month must not exceed 0.5 NTU in systems
				using conventional or direct filtration and must not exceed 1 NTU in systems
				using slow sand or diatomaceous earth filtration or other filtration
				technologies approved by the Department.
7TT - Treatment technique
8There are various regulations that
				set turbidity standards for different types of systems, including the 1989
				Surface Water Treatment Rule (SWTR), the 1998 Interim Enhanced Surface Water
				Treatment Rule (IESWTR), and the 2002 Long Term 1 Enhanced Surface Water
				Treatment Rule (LT1ESWTR). For systems subject to the IESWTR (systems serving
				at least 10,000 people, using surface water or ground water under the direct
				influence of surface water), that use conventional filtration or direct
				filtration, after January 1, 2002, the turbidity level of a system's combined
				filter effluent may not exceed 0.3 NTU in at least 95 percent of monthly
				measurements, and the turbidity level of a system's combined filter effluent
				must not exceed 1 NTU at any time. Systems subject to the IESWTR using
				technologies other than conventional, direct, slow sand, or diatomaceous earth
				filtration must meet turbidity limits set by the Department. For systems
				subject to the LT1ESWTR (systems serving fewer than 10,000 people, using
				surface water or ground water under the direct influence of surface water) that
				use conventional filtration or direct filtration, after January 1, 2005 the
				turbidity level of a system's combined filter effluent may not exceed 0.3 NTU
				in at least 95 percent of monthly measurements, and the turbidity level of a
				system's combined filter effluent must not exceed 1 NTU at any time. Systems
				subject to the LT1ESWTR using technologies other than conventional, direct,
				slow sand, or diatomaceous earth filtration must meet turbidity limits set by
				the Department.
9The bacteria detected by
				heterotrophic plate count (HPC) are not necessarily harmful. HPC is simply an
				alternative method of determining disinfectant residual levels. The number of
				such bacteria is an indicator of whether there is enough disinfectant in the
				distribution system.

				treatment technique violations that involve turbidity exceedances may use the
				health effects language for turbidity instead.

18Surface water systems and ground
				water systems under the direct influence of surface water are regulated under
				R.61-58.10. Community and
				non-transient non-community systems serving greater than, or equal to 10,000
				must comply with R.61-58.13 DBP MCLs and disinfectant
				maximum residual disinfectant levels (MRDLs) beginning January 1, 2002. All
				other community and non-transient non-community systems must comply with
				R-61.58.13 DBP MCLs and MRDLs beginning January 1, 2004. Transient
				non-community surface water systems and ground water systems under the direct
				influence of surface water serving 10,000 or more persons and using chlorine
				dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL
				beginning January 1, 2002. All other transient non-community systems that use
				chlorine dioxide as a disinfectant or oxidant must comply with the chlorine
				dioxide MRDL beginning on January 1, 2004.
19Community and non-transient
				non-community systems that must comply with R.61-58.14 TTHM and HAA5 MCLs of
				0.080 mg/L and 0.060 mg/L, respectively (with compliance calculated as a
				locational running annual average) on the schedule in R.61-58.15.
