State Regulation 10 CSR 60
EXECUTIVE SUMMARY
The Missouri Department of Natural Resources (DNR) is authorized to regulate community and non-community public drinking water supplies under the Missouri Safe Drinking Water Act. Persons that dispense water from a source are required to obtain a permit to dispense water, demonstrate ability to produce water of drinking water quality, routinely test their supply and reliably operate their system. Persons that obtain drinking water from a community water system (i.e. a municipality or rural water district) do not fall within this program. Persons that are on a private well and routinely serve at least 25 people for at least six months out of the year (ex. have drinking water fountains, sinks, or showers) are required to apply in writing to the DNR for a permit to dispense water.
DEFINITIONS
Community water system: A public water system (ex. a municipality or rural water district) which serves at least fifteen (15) service connections and is operated on a year-round basis or regularly serves at least twenty-five (25) residents on a year-round basis.
Non-transient non-community water system: A public water system that is not a community water system and that regularly serves at least twenty-five (25) of the same persons over six (6) months per year.
NOTE: Member cooperatives with a private well that serve a drinking water fountain likely fall into this category.
Transient non-community water system: A public water system that is not a community water system, which has at least fifteen (15) service connections or regularly serves an average of at least twenty-five (25) individuals daily at least sixty (60) days out of the year.
PERMIT REQUIREMENTS
No water may be dispensed or be made available to the public by any person or facility without first applying for in writing and receiving a permit to dispense water from the Missouri Department of Natural Resources. If your facility meets the definition of having a drinking water system, you are required to obtain a permit to dispense water. Use the "Permit to Dispense Application" form to apply.
To obtain a permit, non-community public water systems must present evidence to the DNR that they have the ability to produce water that meets applicable maximum containment levels. You must also demonstrate that you routinely test the water supply and can reliably operate the drinking water system.
EXEMPTIONS
Persons or facilities that obtain drinking water from a community water system (i.e. a municipality or rural water district) do not need a permit to dispense water.
CONTAMINANT LEVELS AND MONITORING
A supplier of water must collect or have collected samples of the water and shall provide for analysis of these samples for designated contaminants. The DNR will establish sampling and analysis methods. Analysis must be done by the DNR, Department of Health, or a laboratory certified by the DNR.
NOTE: Public water systems that get water from a surface water system or system using groundwater under the direct influence of surface water have more requirements.
REPORTING REQUIREMENTS
The supplier of water shall report to the DNR the results of any test measurement or analysis within the first ten (10) days following the month in which the result is received or the first ten (10) days following the end of the required monitoring period as stipulated by the DNR, whichever of these is shortest. Within 48 hours, a supplier of water must report any failure to comply with any drinking water regulation, including failure to comply with monitoring requirements, to the DNR.
RECORD KEEPING
Records must be kept at the facility and maintained for the following:
- Bacteriological and operational analyses must be retained for a minimum of five (5) years
- Chemical analyses must be retained for a minimum of ten (10) years
- Actions taken to correct violations must be retained for at least three (3) years after the last action taken to correct the violation
DNR INSPECTIONS
The DNR, at its discretion, may conduct routine inspections of any public water system or make other necessary inspections to determine compliance with the permit to dispense water. Permitted facilities should expect an announced inspection by the DNR at least once every five (5) years.
DNR inspectors may review the following: waterworks system physical facilities and equipment; administration and recordkeeping; training of operators; sampling techniques and monitoring activities for water quality; the maintenance program for the waterworks system; design and operation of the waterworks system; the competency of the supplier of water; the reliability of the waterworks system; security measures provided to protect water quality and the operation of the water system; and water quality.
