Creek tributaries).Testing Parameters: Used to record field measurements and laboratory analytical data including pH, dissolved oxygen, turbidity, conductivity, temperature, bacterial indicators, and pollutant concentrations.Maintenance & Update Frequency: Periodic / As Needed (Updated when new monitoring stations are established or sampling access locations change)Process Step (Lineage
