Nothing beats processing groundwater samples next to a cornfield! Kelly McVicker (pictured) and Nicole King of our water quality team were on the Eastern Shore of Maryland collecting groundwater samples for selected analyses including per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals.”

Hydrologic technician Tyler Bowser calibrated our new rain gage at Harford Glen Park. For this weighing-bucket rain gage to report accurate data, it must be calibrated to a standard weight. This gage weighs rainfall and converts the weight to rainfall in inches.
