North Santiam Water Quality Monitoring Year 1 Summary E R I C A N D E RS E N R EG I O N A L M O N I TO R I N G CO O R D I N ATO R

Project Background  Started Nov 2012. Will end in Oct 2014.  Paid for through OWEB and OR DEQ 319 grants  Extensive match from OR DEQ for lab analysis  Sample 1 time per month  Measure: Temperature, dissolved oxygen, pH, conductivity, turbidity, total suspended solids, NO2+NO3, total phosphorus, E. coli.  Goal: Characterize baseline water quality conditions in 4 subbasins of the North Santiam.

Why is water quality important? Fresh Water Other Saline 2.5% 1.0% Oceans 96.5% Source: USGS Total Global Water
