Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Carbon and Nutrient Monitoring in the Great Lakes Using Satellite Observations
Carbon and nutrients are the foundation of lake food webs and play an important role in the chemical and physical processes that shape aquatic ecosystems and various lake dynamics. Studying these cornerstones can help improve understanding of other lake conditions like harmful algal blooms, hypoxia, and phytoplankton community composition. The way in which these characteristics are monitored varies, though many rely on a proxy approach wherein parameters are extrapolated from the measurement of a different parameter. An assistant professor at Cleveland State University, Brice Grunert, is working to improve current strategies and take a satellite approach to monitoring the Great Lakes.

Restoring North Texas Streams to Historical Flows
North Texas is one of the fastest-growing regions in the state, an area that is expected to face increasing water needs. In order to meet these demands, the Upper Trinity Regional Water District ( UTRWD ) is building Lake Ralph Hall near Ladonia in southeast Fannin County, Texas. The lake has been in the works since 2003, with construction finally beginning in 2021. The population of the UTRWD is expected to grow 5-fold over the next 50 years, leading to increased water use. Ed Motley, Program Manager with the UTRWD stresses that even with conservation and reuse, new sources like Lake Ralph Hall are essential to meeting near-term and long-term water needs to support regional growth.
