To address community-driven concerns about lead-contaminated drinking water in residential homes in the Greater Fifth Ward neighborhood in Northeast Houston, Texas utilizing participatory-based research. The study collected survey data and performed lead analysis on drinking water from residents’ homes. The Greater Fifth Ward is characterized as a majority-minority environmental justice community and is located within two confirmed cancer clusters. The residents of 172 homes completed a survey and had detectable lead levels in their water samples. Survey results indicated that more than half of the residents (58.2%) were concerned with the water quality and 42.9% rated the drinking water as poor. Water lead levels detected ranged from 0.01 to 22 µg/L. 10.9% of homes exceeding 1 µg/L, and one located exceeded the USEPA’s action limit of 15 µg/L. Homes built prior to 1978 without major renovation had significantly higher levels of lead in their drinking water compared to homes built after 1978 (p-value < 0.05). These findings demonstrate the need for lead testing of residential water in low socioeconomic-status communities, as well as demonstrating the benefits of community engagement and participatory research to address environmental health concerns.

This paper provides a description of the MyCap data collection platform, utilization metrics, and vignettes associated with use from diverse research institutions. MyCap is a participant-facing mobile application for survey data collection and the automated administration of active tasks (activities performed by participants using mobile device sensors under semi-controlled conditions). Launched in 2018, MyCap is a no-code solution for research teams conducting longitudinal studies, integrates tightly with REDCap and is available at no cost to research teams at academic, nonprofit, or government organizations. MyCap has been deployed at multiple research institutions with application usage logged across 135 countries in 2021. Vignettes demonstrate that MyCap empowered research teams to explore and implement novel methods of information collection and use. MyCap’s integration with REDCap provides a comprehensive data collection ecosystem and is best suited for longitudinal studies with frequent requests for information from participants.
