ISO / PPC Scores by State

Unraveling the Trends and Anomalies

Exploring ISO/PPC scores by state uncovers deviations from the national average, with anomalies in states like NJ, SC, and IL, where less than 5% exceed an 8B score. This exploration raises questions about water supply accessibility and the challenges and perceived benefits of obtaining ISO scores, especially in large, sparsely populated states.

State-by-State Analysis: Diverging ISO/PPC Scores and the Quest for the National Benchmark

After looking at national PPC scores, we thought it would be interesting to compare states to the national average.

Again, while we identified a few trends, it’s hard to make broad assumptions about the data.

In general, most states followed a traditional bell curve similar to the national average.

In a previous post, we talked about the number of departments that were stuck at an 8B or higher due to water access limitations. A few states noticeably bucked this trend.

Percent of Departments with Score of 8B or Higher

Less than 5% of departments in NJ, SC, and IL had scores higher than an 8B. Do these states have better access to water supply than most of their peers? Potentially. It also could mean a large portion of departments did not meet the requirements for a rating.

Something else to note: if departments are getting ISO scores knowing that they will get an 8B or higher, there must be some benefit to obtaining an ISO score, even it’s high.

The other takeaway is that Maine, New Hampshire, Vermont, South Dakota, and North Dakota had the highest percentage of departments with a score of 8B or higher. All of these states are large relative to overall population. It may be harder for large, sparsely populated states to obtain low ISO scores. However, Wyoming may be the exception to the rule.

It’s clear that the national average ISO score may not be the right benchmark for all states.
