Ion Flux Study Kick-Off

The ion flux study has kicked off and is currently underway! Fairfax Water will be sampling the raw and finished water at the Corbalis Water Treatment Plant, while Virginia Tech is sampling hourly at a manhole immediately upstream of the Cub Run Pump Station. Sampling will continue for approximately two weeks, accounting for various residence times in the system. All samples will be analyzed for chloride, sulfate, sodium, calcium, potassium, and magnesium. From these data, our goal is to isolate the contributions of a variety of sources to the ion loading at the Cub Run Pump Station, including: raw water from the Potomac River, water treatment, households and businesses’ morning and evening activities, and groundwater infiltration.
