When providing information in public notices for an exceedance of the MCL for E. coli bacteria as prescribed by OAR 333-061-0030 (Maximum Contaminant Levels and Action Levels)(4), the language within quotation marks must be included, exactly as written:
“E. coli are bacteria whose 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.”

(c)

When providing information in public notices for failing to complete a coliform investigation or corrective action as required by OAR 333-061-0078 (Coliform Investigations), the language specified in paragraphs (4)(c)(A) or (4)(c)(B) must be included, exactly as written except for the language within brackets. The language in paragraph (4)(c)(A) must be used when total coliform was detected at a water system and the language in (4)(c)(B) must be used when E. coli was detected regardless of whether the MCL for E. coli was exceeded.

(A)

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 investigations to identify problems and to correct any problems that are found.
[THE WATER SUPPLIER MUST USE THE FOLLOWING APPLICABLE SENTENCES.]
We failed to conduct the required coliform investigation.
We failed to correct all identified sanitary defects that were found during the coliform investigation(s).

(B)

E. coli are bacteria whose 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. 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 investigation to identify problems and to correct any problems that are found.
[THE WATER SUPPLIER MUST USE THE FOLLOWING APPLICABLE SENTENCES.]
We failed to conduct the required coliform investigation.
We failed to correct all identified sanitary defects that were found during the coliform investigation that we conducted.

(d)

When providing information in public notices for failing to complete an Authority approved start-up procedure at a seasonal water system, the water supplier must include specific information about the situation as prescribed by OAR 333-061-0042 (Public Notice)(4)(a). Additionally, if monitoring was required as part of the Authority approved start-up procedure the following language in quotation marks must be included, exactly as written except for the language in brackets where water system specific information must be included: “We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not your drinking water meets health standards. During [compliance period], we did not complete [any or all] required monitoring or testing for coliform bacteria, and therefore cannot be sure of the quality of your drinking water during that time.”

(e)

Turbidity. Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease-causing organisms. These organisms include, bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea and associated headaches.

(5)

Treatment Techniques -- Public Notice Language.

(a)

Acrylamide. Some people who drink water containing high levels of acrylamide over a long period of time could have problems with their nervous system or blood, and may have an increased risk of getting cancer.

(b)

Epichlorohydrin. Some people who drink water containing high levels of epichlorohydrin over a long period of time could experience stomach problems, and may have an increased risk of getting cancer.

(c)

Surface Water Treatment Rule (Giardia, viruses, heterotrophic plate count bacteria, Legionella), Interim Enhanced Surface Water Treatment Rule (Giardia, viruses, heterotrophic plate count bacteria, Legionella and Cryptosporidium), Long Term 1 Enhanced Surface Water Treatment Rule (Giardia, viruses, heterotrophic plate count bacteria, Legionella and Cryptosporidium) and Filter Backwash Recycling Rule (Cryptosporidium). Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses, and parasites which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.

(d)

Groundwater. Inadequately treated or inadequately protected water may contain disease-causing organisms. These organisms can cause symptoms such as diarrhea, nausea, cramps, and associated headaches.

(e)

Use of an emergency groundwater source that has been identified as potentially groundwater under direct influence of surface water, but has not been fully evaluated. This type of source may not be treated sufficiently to inactivate pathogens such as Giardia lamblia and Cryptosporidium.

(6)

Disinfectant and Disinfection Byproducts -- Special Adverse Health Effects Language.

(a)

Total Trihalomethanes (TTHMs). Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.

(c)

Chlorine. Some people who use water containing chlorine well in excess of the MRDL could experience irritating effects to their eyes and nose. Some people who drink water containing chlorine well in excess of the MRDL could experience stomach discomfort.

(d)

Chloramines. Some people who use water containing chloramines well in excess of the MRDL could experience irritating effects to their eyes and nose. Some people who drink water containing chloramines well in excess of the MRDL could experience stomach discomfort or anemia.

(e)

Chlorine dioxide. (where any 2 consecutive daily samples taken at the entrance to the distribution system are above the MRDL). Some infants and young children who drink water containing chlorine dioxide in excess of the MRDL could experience nervous system effects. Similar effects may occur in fetuses of pregnant women who drink water containing chlorine dioxide in excess of the MRDL. Some people may experience anemia.
NOTE: In addition to the language in this introductory text of subsection (6)(e) of this rule, water systems must include either the language in paragraphs (6)(e)(A) or (6)(e)(B) of this rule. Water systems with a violation at the treatment plant, but not in the distribution system, are required to use the language in paragraph (6)(e)(A) of this rule and treat the violation as a non-acute violation. Water systems with a violation in the distribution system are required to use the language in paragraph (6)(e)(B) of this rule and treat the violation as an acute violation.

(A)

The chlorine dioxide violations reported today are the result of exceedances at the treatment facility only, and do not include violations within the distribution system serving users of this water supply. Continued compliance with chlorine dioxide levels within the distribution system minimizes the potential risk of these violations to present consumers.

(B)

The chlorine dioxide violations reported today include exceedances of the EPA standard within the distribution system serving water users. 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 of excessive exposure to chlorine dioxide-treated water. The purpose of this notice is to advise that such persons should consider reducing their risk of adverse effects from these chlorine dioxide violations by seeking alternate sources of water for human consumption until such exceedances are rectified. Local and State health authorities are the best sources for information concerning alternate drinking water.

(f)
