The Be Well Home Health Navigator Program is a prospective, randomized controlled trial (RCT) implemented to compare a community health navigator program to usual care program to reduce contaminants in drinking water.
This 4-year two-armed RCT will involve well owners in Oregon that have private drinking water wells that contain arsenic, nitrate, or lead above maximum contaminant levels.
The intervention leverages the trusted relationship between Cooperative Extension Service (CES) Community Educators and rural well owners to educate, assist and motivate to make decisions and set actionable steps to mitigate water contamination. In this study, CES will serve as home health navigators to deliver: 1) individualized feedback, 2) positive reinforcement, 3) teach-back moments, 4) decision-making skills, 5) navigation to resources, 6) self-management, and 7) repeated contact for shaping and maintenance of behaviors. Usual care includes information only with no access to individual meetings with CES.
Pre-specified primary outcomes include 1) adoption of treatment to reduce exposure to arsenic, nitrate, or lead in water which may include switching to bottled water and 2) engagement with well stewardship behaviors assessed at baseline, and post-6 and 12 months follow-up. Water quality will be measured at baseline and 12-month through household water tests. Secondary outcomes include increased health literacy scores and risk perception assessed at baseline and 6-month surveys.
The results will demonstrate the efficacy of a domestic well water safety program to disseminate to other CES organizations.

“健康居家水质导航计划”是一项前瞻性随机对照试验（RCT），旨在比较社区健康导航计划与常规护理计划对减少饮用水污染物的效果。
这项为期4年的双臂随机对照试验将涉及俄勒冈州拥有私人饮用水井且砷、硝酸盐或铅含量超过最大污染物水平的井主。
该干预措施利用合作推广服务（CES）社区教育工作者与农村井主之间的信任关系，进行教育、协助并激励他们做出决策并制定可行步骤以减轻水污染。在本研究中，CES将充当家庭健康导航员，提供：1）个性化反馈；2）积极强化；3）教学反馈时刻；4）决策技能；5）资源引导；6）自我管理；7）为塑造和维持行为进行反复联系。常规护理仅提供信息，不安排与CES的单独会面。
预先设定的主要结果包括：1）采取减少水中砷、硝酸盐或铅暴露的处理措施，这可能包括改用瓶装水；2）参与在基线、6个月和12个月随访时评估的水井管理行为。将通过家庭水质检测在基线和12个月时测量水质。次要结果包括在基线和6个月调查时评估的健康素养得分提高和风险认知。
研究结果将证明一项家庭井水安全计划向其他CES组织推广的有效性。
