Preferential pathway definition
Preferential pathway means conditions which act as a pathway permitting contamination to migrate through soils and to groundwater at a faster rate than would be expected through naturally occurring undisturbed soils or unfractured bedrock including but not limited to wells, cisterns, tile lines, drainage systems, utility lines and envelopes, and conduits.
Preferential pathway means a high-permeability conduit that allows contamination to migrate through soils and groundwater at a faster rate than would be expected through naturally occurring undisturbed soils or unfractured bedrock such as a utility penetration; line; drain; building sump or drainage pit; elevator shaft; fractured bedrock; or gravel;
