Remote Water Quality Monitoring with the Oklahoma Water Resources Board

Growing up surrounded by water, whether it be rivers or streams, lakes or ponds or right on the coast of the ocean, it can be easy to forget that clean water is a limited resource. For many, turning on the tap means potable, running water—“You’re not really thinking, ‘well this comes from a reservoir,’” explains Sarah Dexter, an Environmental Program Supervisor with the Oklahoma Water Resources Board (OWRB). The OWRB monitors various waterbodies throughout Oklahoma, and Dexter works specifically with rivers and streams, which has placed her on several projects involving dams and stormwater monitoring.

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

From the Tap: Source Water Monitoring for Public Health

In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.
