Non-Radiological Monitoring of Ambient Surface Water

Image of person collecting air samplesESOP conducts onsite stream monitoring at SRS to determine surface water conditions and detect nonradiological impacts from SRS operations.

We collect samples once a month from each of nine routine surface water locations (Non-Radiological Surface Water Monitoring locations). We have them analyzed for field parameters such as pH, dissolved oxygen, and temperature.

Lab analyses include turbidity, biochemical oxygen demand, E. coli, nitrate/nitrite, metals, mercury, total suspended solids, and many more. We collect biannual samples for pesticide and polychlorinated biphenyl (PCB) analyses.

We will continue the non-radiological independent monitoring and surveillance of SRS surface water to verify and validate water quality. Continued monitoring is required because of increased land disturbance from accelerated clean-up, new facility construction, logging, and new SRS missions. We review and modify the locations, numbers of samples, sample frequencies and monitoring parameters annually to maximize available resources and address SRS mission changes.
