The physical, chemical and biological properties of water – together termed water quality – vary in space and time in response to interactions among weather, rocks and life. These interactions are increasingly influenced by the cumulative footprint of humanity, with water appropriation and disposal, climate change, land use intensification, and a growing array of contaminants threatening water resources, ecosystem integrity and human health. Understanding water quality as water moves between land, sea and air is our fundamental charge.
The water quality technical committee (WQTC) is comprised of a broad array of scientists and engineers interested in furthering our interdisciplinary understanding about the materials (solutes, sediments, biota) that water carries. We work on water quality questions across scales, issues, and processes to facilitate a cross-disciplinary conversation – along with colleagues from other sections of AGU – about grand challenges like eutrophication, plastic pollution, acidification, the growing use of nanomaterials, the sustainability of food production, and climate change. Among our primary roles is to develop cross-cutting special sessions at the AGU Fall Meeting that explore the many facets of water quality, from watershed source tracking to ecological controls to human impacts. Our committee is always seeking input from the community for the development of these sessions. Please contact us if you are interested in participating on the committee or proposing a special session at the next meeting.
