Outline: main points Silver Bow Creek is severely impacted by nutrient overload Concentrations of specific nutrients change over very short time and spatial scales Seasonal effects are also significant The Warm Springs Ponds act as a huge sink for nitrogen Stable isotopes may reveal clues to processes of nutrient cycling

Butte WWTP effluent entering Silver Bow Creek (3-10 cfs) Ammonium: NH4+ Phosphate: PO43- Nutrients in WWTP effluent

Other point discharges in Butte Lower Area One (LAO) Montana Pole (MT Pole) Grad Student Bev Plumb 1-2 cfs lime-treated groundwater ~ 1 cfs Treated PCP plume

Non-point sources: Butte Valley Septics Fertilizers Animal waste Blacktail Creek in July

Load comparisons Total dissolved inorganic N Soluble reactive P

Comparison of SBC to reference streams SBC with WWTP SBC without WWTP Trend lines from Smith et al. (2003)

Effects of nutrient overload Massive growth of algae and plants Night-time hypoxia Undergrad student Brian Kuhn

Nitrification (oxidation) of ammonium Step One: oxidation of ammonium to nitrite NH4+ + 1.5 O2 → NO2-+ 2H+ + H2O Step Two: oxidation of nitrite to nitrate NO2- + ½ O2 → NO3- N-oxidizing bacterium
