(1) States were not included if all monitored counties got a grade of B or higher.
(2) The weighted average was derived by adding the three years of individual level data (2002-2004), multiplying the sums of each level by the assigned standard weights, i.e. 1=orange, 1.5=red,
2.0=purple, and calculating the average.
(3) Grades are assigned by weighted average as follows: A=0.0, B=0.3-0.9, C=1.0-2.0, D=2.1-3.2, F=3.3+.
