POU arsenic filter installation and water sampling
Missouri Breaks Industries Research, Inc. (MBIRI), a local American Indian owned and led research organization, managed and organized study activities. After enrollment, each study household received a Multipure® (Model CB-As-SB, Las Vegas, NV) POU arsenic filtration system installed under the kitchen sink. Filter installation was completed by community members working at the Tribal Housing Authority in partnership with the IHS. At installation, households were provided with device use instructions and one replacement filter cartridge. A cartridge change was recommended every 12 months. The POU arsenic filter was connected to a filter faucet installed alongside the kitchen faucet for drinking and cooking water use. Based on feedback from the pilot study, the POU arsenic filter faucet was also connected to the refrigerator water and icemaker on request [
