MILLVILLE — CU Maurice River, with the assistance of the National Park Service, has once again been included in a national study of mercury deposition within the United States. Over the three-day period, Aug. 4-6, volunteer citizen scientists will sample at three different sites within the Wild and Scenic Maurice River Watershed. This year’s project activities will be conducted in the northernmost tributaries of the Menantico and Manumuskin Rivers. Precise locations will be shared prior to this effort. Citizen Scientists will meet at the CUMR Office for a short introductory presentation on the Dragonfly Mercury Sampling project before heading out into the field. The office is located at 17 E. Main St. For more information call 300-5331.
