Compilation of Rules and Regulations of the State of Georgia › Department 391 - RULES OF GEORGIA DEPARTMENT OF NATURAL RESOURCES › Chapter 391-3 - ENVIRONMENTAL PROTECTION › Subject 391-3-5 - RULES FOR SAFE DRINKING WATER › Rule 391-3-5-.14 - Operation

Current through Rules and Regulations filed through June 27,
				2024
(1)
Compliance with Safe Drinking Water Rules.
A supplier of water
				shall treat the water supplied so the water complies with the Safe Drinking
				Water rules of this Chapter. Public water systems shall not use bottled water
				to achieve compliance with a maximum contaminant level (MCL). Bottled water may
				be used on a temporary basis to avoid unreasonable risk to health. Community
				and non-transient non-community water systems shall not use point-of-use or
				point-of-entry treatment units to achieve compliance with an MCL or a treatment
				technique requirement.
(2)
Continuous Chlorination.
The supplier of water must continuously
				chlorinate the water to maintain a detectable residual of free chlorine in all
				parts of the distribution system in the recommended amount of at least 0.2
				parts per million, and such additional amounts as may be determined necessary
				by the Division, unless other means of disinfection have been approved by the
				Director. If the residual disinfectant concentration is measured by approved
				analytical methods and not detected, the supplier may, upon approval by the
				Division, determine and report detectability by the use of heterotrophic plate
				count measurements as required by
				40 CFR §
										141.72 (1989) and other applicable paragraphs
				of 40 CFR Part 141.
(3)
Disinfection Waiver.
After consideration of the microbiological
				quality of the source of water supply, the local geology, the population served
				and the extent of the water distribution system, the disinfection treatment may
				be waived by the Director.
(4)
Fluoridation Requirements.
The supplier of water of a fluoridated
				public water system shall daily sample and analyze the fluoride concentration
				of the drinking water. Daily records of the analytical results shall be kept on
				forms provided by the Division or on forms acceptable to the Division and a
				copy of the result submitted to the Division in accordance with Rule
				391-3-5-.30.
(5)
Surface Water Source Certified
				Operator.
A supplier having a surface water source must have a certified
				operator on duty and onsite at all times when the water plant is in operation.
				A supplier having a groundwater source under the direct influence of surface
				water must have a certified operator on duty and onsite at all times when the
				water plant is in operation, unless otherwise approved by the Division,
				depending upon the complexity of the water treatment processes, quality of the
				water sources, and the size of the system.
(6)
Groundwater Source Certified
				Operator.
A supplier having only ground water sources must have a
				certified operator to comply with the classification prescribed in Section
				391-3-5-.39 of this Chapter. The
				Director may find that the availability of a certified operator to a system
				with only groundwater sources is sufficient to comply with Section
				391-3-5-.39 of this Chapter and may
				so allow, but only if the Director determines that the complexity of the water
				treatment processes, quality of the water sources, and the size of the system
				so warrant.
(7)
Record
				Maintenance.
The supplier of water shall maintain daily records of the
				operation of the water treatment facility and water distribution system as may
				be required by the Division including the amount of water treated daily,
				results of the performance of daily tests pertinent to the control of the water
				treatment processes, disinfectant residuals, and tests performed in the water
				distribution system. Daily records shall be kept by the supplier on forms
				furnished by the Division and a copy of the record submitted to the Division in
				accordance with Rule
				391-3-5-.30. Based on the complexity
				of the water treatment process, the quality of the water sources, and the size
				of the system, the Director may establish less frequent maintenance of record
				requirements for small groundwater systems.
(8)
Microbiological Laboratory.
All community water systems which have a surface water source with water
				treatment facilities and those public water systems having only a ground water
				source or only a water distribution system and serving a population of more
				than 12,900 must have, or have available, the services of a microbiological
				laboratory certified by the Division to perform the microbiological tests
				necessary for compliance with the maximum microbiological contaminant levels.
				The laboratory and equipment must be kept in good working order at all
				times.
(9)
Summary
				Microbiological Analytical Results.
A supplier of water required to
				have, or have available, a microbiological laboratory under paragraph (8) of
				Section 391-3-5-.14
				shall collect and analyze drinking water samples in accordance with the minimum
				number specified in paragraph (1) of Section
				391-3-5-.23 and such additional
				samples as may be required by the Director. The supplier shall furnish the
				Division, on forms provided by the Division, a monthly microbiological summary
				of the number of samples analyzed and the results in accordance with Section
				391-3-5-.30.
(10)
Routine Microbiological
				Samples.
The supplier of water shall collect routine drinking water
				samples for microbiological analysis as follows:
(a) the minimum number of routine samples per
				month shall be in accordance with paragraph (1) of Section
				391-3-5-.23;
(b) at the treatment plant and at various
				points in the distribution system which are representative of the drinking
				water when three or more samples per month are required; or
(c) at various points in the distribution
				system which are representative of the drinking water when only one or two
				samples per month are required.
