N.H. Admin. Code § Env-Dw 804.01

Current through Register No. 1, January 2, 2025

Section Env-Dw 804.01 - Required Health Effects Language for Microbiological Contaminants

(a) The O/O shall use one or more of the statements listed in (b) through (h), below, as applicable, as the statement required by Env-Dw 801.03(a)(3) to describe the adverse health effects for microbiological contaminants specified in Env-Dw 702.

(b) For an E.coli detection or MCL exceedance, the statement shall read as follows:

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) For total coliform assessment and corrective action violations, the statement shall read as follows:

"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 were found during these assessments."

(d) For total coliform assessment and corrective action violations, the O/O also shall include one of the following statements, as applicable:

(1) "We failed to conduct the required assessment."; or

(2) "We failed to correct all identified sanitary defects that were found during the assessment(s)."

(e) For E.coli assessment and corrective action violations, the statement shall read as follows:

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."

(f) For E.coli assessment and corrective action violations, the system also shall include one of the following statements, as applicable:

(1) "We failed to conduct the required assessment."; or

(2) "We failed to correct all identified sanitary defects that were found during the assessment we conducted."

(g) For the presence of Giardialamblia, the statement shall read as follows:

"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."

(h) The O/O shall use the following as the statement required by Env-Dw 801.03(a)(3) to describe the adverse health effects when there is a violation of the treatment technique for filtration and disinfection specified in Env-Dw 716:

"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."
