Scalability of a Home Health Navigator Program to Reduce Arsenic, Nitrate,

Status Recruiting

Clinical Trial Summary

Approximately 34 million Americans rely on private wells to supply their drinking water. Private wells are excluded from the Safe Drinking Water Act. Consequently, people who use private wells have not benefited from pollution prevention activities mandated by this law. This is a public health concern because toxic chemicals such as arsenic, nitrate, and lead are frequently detected in drinking water provided by private wells at concentrations that exceed the Safe Drinking Water Act's maximum contaminant levels. Chronic exposure to toxics in drinking water increase the risk of several chronic diseases. Several states in the U.S. have implemented or are proposing legislative policies to require testing and treatment of private wells and it is critical that public health agencies offer a program to aid homeowners with adherence to these new policies. Subsequently, there is a need to determine if individual-level interventions would be more effective for promoting behaviors that would reduce, mitigate, or eliminate exposure to contaminated well water. Lay health care workers may be able to provide cost-effective counseling to promote environmental health decision making among homeowners that have contaminated wells. This study will involve a community efficacy trial that brings together university-based researchers, State and Local agencies, and Extension Services. The community efficacy trial will be implemented by community health navigators via the Extension service. Specifically, it will involve a randomized controlled trial in Oregon to test the acceptability, fidelity, scalability and efficacy of 2 different intervention arms to reduce harmful toxicant exposures through the adoption of appropriate well water treatment. Upon completion, it will will produce a private well safety intervention program that has been tested and modified through empirical research. By capturing the costs and retaining the most efficacious intervention components, our cooperative approach has a better chance of scalability into practice across multiple stakeholders (i.e. Extension services, state health agencies). This information has the potential to reduce health disparities in rural America that are related to a household's source of drinking water.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
