But such a review would take a significant amount of time and money, so it was decided not to do such a review. Sensitivity of his method to measure change in alkalinity is about 1 cfs of measured CBM flow. For Na, it can detect a change due to 4 cfs of CBM water reaching the river. Could detect changes within 6 months to a year. Their method could detect changes within one season.
Sensitivity is unknown.
To solve the problem of which method to use, one suggestion was to look at other areas that has similar problems and have devised methods to determine measurable change . One example was measuring salt on the Colorado River, but that situation has more data to supply good baseline data, and is not comparable to the Powder or Little Powder which have minimal historical data. Pat Newby- Suggested that PAW should evaluate how their method works by using it on historic data at Locate. MDEQ- Suggested turning discussion to the Little Powder. On the Little Powder, the method proposed by PAW would likely be acceptable because the historic data on the Little Powder is representative of current conditions.
