Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content. If a change is noted in the mill certificate, air-entraining agent dosages may need adjustment. Above 0.60%, alkali changes of 0.1% can be significant.
The Animas River between Maggie Gulch and Cement Creek in Silverton supports brook trout and a substantial inver-tebrate community, suggesting that water and habitat qual-ity in this reach is improving. The Animas River watershed study area is a highly complex system whose complexity is increased by more than 5,300 inactive mine, mill, and prospect
