1. No Significant Correlation for Studied Water-Quality Constituents Montgomery & Associates found no statistically significant correlation between pumping or groundwater-level trends and nitrate trends in the Forebay and Upper Valley, or gross alpha trends in the Upper Valley. The committee supported no water-quality action levels tied to pumping at this time and recommended repeating the analysis at a future five-year periodic evaluation, beginning with the one after the current cycle. Staff may use the analysis in annual reports when assessing whether new exceedances involving the studied constituents are attributable to pumping; it does not rule out future pumping effects.
