For the following Action Level Source: 

CEQG Soil Quality for the Protection of Env. and Human Health (various land uses)

 The Comment for n-hexane action level is incorrect.

Currently says: " Higher Concentrations applicable in subsoil or Coarse Soil"

 should say: " Higher Concentrations applicable in  Fine Soil".

 I.e. n-hexane has a lower guideline in coarse soils, unlike the BETX compounds.
