| #Q001 | administrative | operational | recommended | Obtain Implementation Guidance | drinking water | Specific guidance related to the implementation of drinking water guidelines should be obtained from the appropriate drinking water authority in the affected jurisdiction. | | high |
| #Q002 | monitoring | operational | guidance | Infrequent Monitoring of Naturally-Occurring Fluoride | drinking water | Frequent monitoring of naturally-occurring fluoride levels is generally not required, as these levels are not expected to change rapidly. | When dealing with naturally-occurring fluoride levels in the water source | high |
| #Q003 | treatment | health | guidance | Consider Alternate Source or Treatment for High Fluoride | drinking water | In such cases, the homeowner may wish to consider residential scale treatment or an alternate source of drinking water, especially where young children are exposed on a regular basis. | Some groundwater sources may have naturally-occurring levels of fluoride significantly above the MAC of 1.5 mg/L | high |
| #Q004 | corrective_action | health | recommended | Develop Plan for Elevated Fluoride Levels | drinking water | However, in the event that monitoring data show elevated levels of naturally-occurring fluoride, it is suggested that a plan be developed and implemented to address these situations, with an emphasis on young children. | In the event that monitoring data show elevated levels of naturally-occurring fluoride | high |
| #Q005 | monitoring | operational | recommended | Monitoring and Reporting Program for Fluoridating Municipalities | drinking water | Municipalities that choose to fluoridate their drinking water supply should establish a full monitoring and reporting program for fluoride levels in drinking water to ensure that the target fluoride level is being applied at all times. | Municipalities that choose to fluoridate their drinking water supply | high |
| #Q006 | design | treatment | mandatory | Reverse Osmosis System Certification Capability | drinking water | At the residential scale, reverse osmosis systems can be used at the point of use, and must be capable of reducing the concentration of fluoride in water to a maximum of 1.5 mg/L to be certified. | Residential scale reverse osmosis systems used at point of use for certification | high |
| #Q007 | design | treatment | mandatory | Distillation System Certification Capability | drinking water | Distillation systems installed at the point of use are effective to remove inorganic contaminants, including fluoride, and must be capable of reducing fluoride levels to a maximum of 2.0 mg/L to be certified. | Distillation systems installed at point of use for certification | high |
