| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention Group | Experimental | Participants will test their home tap water using kits mailed to their homes, with phone or Zoom assistance from the research team. Families with water quality concerns will receive remediation tailored to the issue (e.g., flushing guidance, filtration device and installation guidance). Participants will also receive reusable water bottles, educational handouts and videos, and phone or Zoom sessions with the research team that include motivational interviewing to set healthy beverage goals. |
|
| Control Group | No Intervention | Participants will not receive water testing kits, filtration devices, or educational resources during the study. After the study concludes, participants will have access to the intervention materials. |
