Dear CLEA Users
Can some of you verify that CLEA-1.04 is calculating the Soil Assessment
Criteria (SAC) correctly.
There might be a small systematic error in the goal seek for indoor air (need to
check other pathways). I think 1.03 did the same.
To Test. Select indoor air pathway for residential and run each age class
separately and then all together. Then look at %Average Daily Exposure for
the CLEA output and an alternative SAC calculated separately from CLEA.

Interested to know if anyone else can replicate or think there is an issue.
