Gregory Pierce, co-director of the UCLA Luskin Center for Innovation, spoke to Capital & Main about how to help communities facing water quality challenges. A newly updated tap water database by the nonprofit Environmental Working Group includes drinking water data between 2014 and 2019 across all 50 states, illustrating wide disparities in water quality across systems. People living in underserved communities, especially in areas with high Black and Latino populations, face a disproportionate risk, the data showed. Pierce said the database provides an impressive translation of federal and state data and also raises wider questions, such as what alternatives are readily available to vulnerable communities facing water quality challenges. He noted that clear-cut answers are not always easy to come by, since bottled water is also associated with high costs and loose regulations. “Unless a system’s failing to meet the basic regulatory standards, I don’t think there’s a good case to say that bottled water is better,” Pierce said.
