Combating Water Insecurity Through Real-Time Systems

In regions impacted by water insecurity, water quality monitoring can be foundational in improving water treatment and informing environmental regulations that protect source water. Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan, relies on real-time water quality monitoring systems in her work, focusing on making the region more water secure. Challenge: Worsening Water Quality and Water Insecurity While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Most of Baulch's work has focused on Buffalo Pound Lake, a source water resource that supplies drinking water to two cities.High nutrient loads and organic carbon in Buffalo Pound Lake have deteriorated its water quality over time. Additionally, the lake is very shallow, so it stratifies periodically, which can influence its chemical and physical properties. The main concern for Baulch is cyanobacterial behavior in the lake, as well as the impacts of dissolved organic carbon on disinfectant byproducts.

Monitoring Source Water to Optimize Water Treatment

Monitoring Source Water to Optimize Water Treatment

Monitoring Source Water to Optimize Water Treatment

Clean drinking water is necessary for all human life, and source water monitoring is the first step in the long process of converting source water into tap water. Millions of people rely on the work of analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, to convert wastewater into potable water.Source water monitoring gives treatment plants insight into incoming water conditions, allowing them to begin taking the necessary measures to properly treat such water. Without data collected and analyzed by Gilkerson and her team, plants would be ill-prepared for poor water quality. In the case of nutrient-rich water loads, specific technology is required to treat the water in addition to the treatment plant’s usual procedures. Challenge: Meeting Safe Drinking Water Act Standards For example, a nitrate event that goes improperly treated can be the beginning of a taste and odor event—wherein the water may meet Safe Drinking Water Act standards but tastes or smells strange to the average consumer. While not always an indicator of safety, making sure drinking water meets expectations is important to protecting the relationship between the division and the public who rely on them for water.

The Coral Reef Early Warning System (CREWS)

Corals around the world are under threat. The buoys of the Coral Reef Early Warning System (CREWS) help face that threat, providing the entire world with weather patterns and data about climate change from their home in the Caribbean Sea.Since June 2018, a new, state-of-the-art oceanographic buoy has added ocean state and weather data in near real-time to the CREWS system—all accessible from a computer or smartphone. A better understanding of more threatened regions Installed by the Central Caribbean Marine Institute (CCMI), which runs the CREWS system, the CCMI team helped describe the challenges the CREWS system needs to tackle.
