It’s officially summer, making for a hot month of water quality monitoring for the water team.

Follow along with research specialist Amanda Tague, along with water interns Ariana Cavazos and Audrey Vasquez, as they collect water quality measurements and samples for measuring levels of per- and polyfluoroalkyl substances, or PFAS, at Middle Yegua Creek.
