The laboratory reported that concentration levels are high, yet ';. they do fall rapidly with depth. It is AquaGeosciences, InC opinion that based on the laboratory analysis, addi tional work related to subsurface contamination is warranted. We recommend that you forward a copy of this report to Mr. Joe Dunwoody of the City of Bakersfield Fire Department Hazardous Materials Division.
