A Review of the EPA's New Drinking Water Training System

The newest tool released by the EPA allows operators to learn about national primary drinking water regulations through an online and self-paced training system. According to the EPA, this system was developed at the request of states, water associations, and operators. Stakeholders wanted operators to have accessible regulatory training easily available to an industry where shrinking resources and a retiring workforce make taking time away from water facilities difficult.

Approximately 130 training modules on various drinking water rules make up the system. The modules runs well in most browsers as long as Adobe Flash is installed and running. Both audio and closed captions are available during the training with the option to run the modules at your own pace. To use this system, each operator will have to create their own account using an email address that has not been registered prior.

The system has a fairly easy setup. When an operator signs in, the homepage shows an Announcements section that will update users on new modules or changes to the system. Operators can design their own lesson plan for the regulations that apply to their system under the Curriculum Builder. The Builder asks questions about the system type, source water, and treatment methods. A new curriculum can be made and started at any time with each curriculum found under the Curriculum List.

Usually 5-15 modules will make up a curriculum. Each module will cover a different rule with a quiz of 4-5 questions at the end. The operator must answer each question correctly to pass. If operators want to run through the modules individually they can find a list under the Course Catalog tab, however this mode does not offer quizzes or completion credit by the system. A complete list of training modules available as of May 2019 can be found here.

An interesting feature to note about the training is that within each module slide includes the CFR citation number so operators can find the corresponding rule in the Code of Federal Regulations. It should also be noted that these topics cover federal regulations only and do not apply to states with stricter drinking water requirements.

When a training has been completed, the Certificates tab will create a print out certificate of the desired curriculum. The only drawback for operators is that this training is not pre-approved for CEUs in any states as of yet. To provide credit, a state primacy will have to review each of the 130 modules. The next plans for this training system involves designing new modules on Special Drinking Water Topics. While these modules have yet to be developed, drinking water operators can look forward to those resources in the future!

An Overview of Drinking Water Fluoridation

With cost efficiency community fluoridation overcomes disparities in oral health regardless of community size, age, education, or income level. A dental health study found that the savings from fluoridation in communities of 1,000 people or more exceeded program costs by $20 per every dollar invested. When Juneau, Alaska voted to end fluoridation in 2007, a study found that children six years and under had an increase of one dental cavity per year, roughly equivalent to $300 in dental costs per child annually. Juneau’s increase in cavities was also reflected in adults.

All water contains some levels of naturally-occurring fluoride though these levels are often too low for health benefits. In untreated water, fluoride levels vary considerably with geology and land practices. Fluoride is introduced to water when dissolved from the Earth’s crust into groundwater or discharged from fertilizer and aluminum factories. Systems with fluoridation should set final levels near 0.7 mg/L as suggested by the Department of Public Health. This concentration factors for other sources of consumer fluoride exposure such as toothpaste. Fluorosilicic acid (FSA) is most commonly used in water treatment. Though fluoridation decisions are left to a state or local municipality, the EPA has established federal standards for the upper limits allowed in drinking water.

At high levels fluoride can cause the development of bone disease and tooth mottling. As a result, the EPA has set both the Maximum Contaminant Level Goal (MCLG) and the MCL for fluoride at 4 mg/L. Levels higher than 4 mg/L can lead to increased rates of bone fracture, Enamel Fluorosis, and Skeletal Fluorosis. If systems find fluoride concentrations higher than the MCL, they are required to notify customers within 30 days and potentially install treatment methods such as distillation or reverse osmosis to remove the excess fluoride. 

The EPA has also set a secondary standard for fluoride at 2.0 mg/L. The secondary standard is intended to be used as a guideline for an upper bound level in areas with high levels of naturally occurring fluoride. Below this level, the chance for tooth mottling and more severe health impacts are close to zero. Even if the secondary standard is reached, systems must notify customers. In the U.S. very few systems have exceeded the fluoride MCL at all. Where violations have occurred, the concentrations are generally a result of natural, geological conditions. 

Even with this track record, some concerned customers are still weary of fluoridation. When customers broach fluoridation concerns, operators can offer educational materials and refer customers to consumer confidence reports. The CDC and the EPA offers a variety of consumer-friendly educational material that operators can reference in addition to the resources linked in this blog post. Remember that good customer service starts by establishing a trusted relationship with your community.
