About the following data DW monitors inlets and outlets of Dillon Res. 8 times/year. – 4 events in high-flow season (May-Aug.) – 4 events in low-flow season (Sept.-April) DW has followed this monitoring design for over a decade. Samples from all events are tested for both “dissolved” (filtered) and “total” (acid digested) metals. All metals tests are for the same suite of 27 trace and “major” elements, including molybdenum. In general for Dillon Res. area monitoring, Mo in the dissolved fraction is nearly identical to the total fraction, indicating most Mo from this monitoring is “soluble”. Dissolved Mo shown here.
