ClinConnect Summary

This clinical trial is studying whether a special table-top water pitcher with a filter can help reduce arsenic, a harmful substance, in the drinking water of people who use private wells in New Hampshire. The study wants to see if using this pitcher lowers arsenic levels in both the water and the body over time, and to understand what makes it easier or harder for people to keep using the filter regularly. Researchers are also interested in whether factors like household income or owning a home affect how consistently people use the pitcher.

To join the study, participants must be 18 or older, live in New Hampshire, get their main healthcare at certain clinics, use a private well for most of their drinking water, and do most of their cooking at home. They also need to have arsenic levels in their water above a certain limit. Participants will receive a free water filter pitcher and replacement filters, use the pitcher as instructed, and provide water and urine samples at the start, after 4 weeks, and after 12 weeks. They will also fill out online questionnaires during these times. This study is not yet recruiting but aims to help families using well water reduce their exposure to arsenic safely and effectively.
