Target-setting method details
Linear trend fitted using ordinary least squares and a projection at the 25 percent prediction interval.
Target-setting method justification
Trend data were evaluated for this objective. Using historical data points, a trend line was fitted using ordinary least squares, and the trend was projected into the next decade. This method was used because three or more comparable data points were available, the projected value was within the range of possible values, and a projection at the 25 percent prediction interval was selected because there has been a steady but gradual increase in the number of community water systems meeting the Safe Drinking Water Information System 2008.
Comparable HP2020 objective
