Sensing, knowing, and making water quality along Marikina River in the Philippines

Water quality is a major concern around the world, but assessments of quality often privilege producers, regulators and experts over consumers. With water supplies and sources constantly in flux, how do ordinary people experience and "sense" quality? How do they define "good" or "good enough" water, and what practices do they engage in to "make" good water? In this article, we attend to these questions by presenting findings from an open-ended qualitative study carried out along the Marikina River, Manila, the Philippines - a waterway that courses from rural and mountainous villages to highly urbanized communities. First, we describe the sensorial and cognitive attributes that people associate with the different water sources in their environment, as well as their decision-making regarding what kind of water to use for which purposes. Second, we present the "making" of water quality: how, in a context of polluted environments and water scarcity, do people try to secure water they consider acceptable for themselves and their families. Our findings reveal water quality as a contested, relational domain-one that reinforces social and health disparities and calls for further scholarship.
