In Miami-Dade County, efforts to improve urban water quality and mitigate the downstream effects of poor water quality on marine ecosystems in Biscayne Bay is a rising concern. Past studies in southeast Florida suggest water quality is linked to climate trends as well as urban land use/land cover. This study analyzes spatiotemporal trends in water quality (WQ) data from Miami-Dade County’s Department of Environmental Resources Management (DERM), which includes 400 water quality variables and over 580,000 bimonthly to monthly measurements recorded at 65 water sampling stations over 1979-2016. We integrate these data with climate (e.g. rainfall) data as well as land use/cover, especially vegetated and impervious covers, in order to investigate how land cover, drainage infrastructure, and seasonal and long term climate trends shape water quality outcomes at a range of spatial scales (hydrological units). Insights from this analysis will help with long-term efforts to manage and improve water quality in Miami-Dade County, particularly in Biscayne Bay. This research is a part of the Urban Resilience to Extremes (UREx) Sustainability Research Network (https://sustainability.asu.edu/urbanresilience/), and will help inform research and practitioner objectives linked to climate vulnerability and resilience.
