PATH’s Safe Water Project joined a number of partners in an effort to monitor and better understand the increased use of a water-treatment product, WaterGuard, among groups of new mothers in Malawi. The chlorine-based water treatment product was made available to pregnant women at antenatal care clinics as part of a hygiene kit. Uptake and use of the product rose sharply, not only among these women, but also among friends and relatives. PATH conducted qualitative research involving in-depth interviews to better understand why this uptake occurred.
