Section R309-220-15 - Standard Health Effects Language

(1) Total Coliform. 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 assessment(s) to identify problems and to correct any problems that were found during these assessments.

(2) Coliform Assessment and/or Corrective Action Violation. 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 assessment(s) 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).

(3) E. Coli Assessment and/or Corrective Action Violations. 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 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.

(4) E. coli. 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

(5) Seasonal System TT Violations. When this violation includes the failure to monitor for total coliforms or E. coli prior to serving water to the public, the mandatory language found at R309-220-8(4)(b) must be used. When this violation includes failure to complete other actions, the appropriate elements found in R309-220-8(1) to describe the violation must be used.
