The Watchung series was reclassified as: Fine, mixed, mesic Typic Endoaqualfs in January 1995. You
are correct that the type location and other silt loam and loam surface textural phases are probably
Albaqualfs.
I brought this to the attention of Roy Pile, Soil Data Quality Specialist in Morgantown West Virginia.
Roy is doing the correlations in the area where the Watchung series is used. You may want to E-mail
Roy directly. His E-mail is: rpyle@wv.nrcs.usda.gov
