9. Low pH Waters

10. Travertine and High pH Waters

11. DIC in Rivers
Decomposition dominates over photosynthesis, so tend to produce CO2 rather than consuming
- Respiration can be so high that CO2 is maintained above equilibrium
Inflowing water high in CO2 from bacterial respiration
High turbulence causes CO2 to be lost quickly, but can see high CO2 in non-turbulent areas and during low flows
Rivers and streams also act to move alkalinity (i.e., HCO3- and CO32-) to lakes or to the ocean
