Exposure to arsenic from private wells declined among American Indian communities that received free kitchen faucet filters and periodic health check-ins through phone calls and home visits, according to researchers at the Columbia University Northern Plains SRP Center.
The team recruited participants from a Northern Great Plains American Indian Nation whose private wells contained high arsenic levels. After receiving community input on study design and implementation, the researchers randomly divided 50 households into two groups. Both received free filter installation at the kitchen faucet, as well as three check-in phone calls from a mobile health program.
The results show that point-of-use filter installation, combined with mobile health check-ins, can reduce arsenic exposure among American Indian communities, according to the authors.
