- 30. Rio Quilcay Glacier fed headwaters Melt routed through shallow wetlands Metamorphic sedimentary rocks, sulfide deposits Large pastureland and eventual municipal water supply How is water quality impacted along flow paths from headwaters?
- 31. Discharge = ~1.2 m 3 /s, ~3/5 from NE, ~2/5 from NW
- 32. Unusual tributary in northeast Below convergence Lake feeding northwest branch
- 33. Alpine vegetation (w/o lake drainage) Wetlands Less Vegetation Lakes pH rapidly decreases downstream, then increases
- 34. Sulfide mineral oxidation tributary: Elevated concentrations of DOC, all metals (except Cu, Pb)
- 35. Fortner 1 Cameron et al., 1995; 2 Schuster, 2005 Tributary exceeds WHO drinking water standards
- 36. Silicate Weathering in Glacial Meltwater from the Cordillera Blanca Relative to specific runoff, high cation flux indicates high chemical weathering rates
Hinweis der Redaktion
- White line elevation of highest mountains in the grid used to make the model. Triangles are the elevations of the highest mountains at those latitudes. The white area was not modelled.
- In Peru, glacier melt is important not only for hydropower, but for agricultural and domestic use. Therefore, it it is important to understand stream geochemitsry and how it relates to human heath. Will water quality get worse with the loss of glacial melt?

- Thank you for inviting me here. It is my pleasure to speak to you about Mountain Glacier Melt Geochemistry and share some insights from reesearch in the Antarctic Dry Valleys and the Cordillera Blanca, Peru
- Make note that headwaters are neutral
