     Analysis Holding Time Compliance
     If samples are identified below as having been analysed or extracted outside of recommended holding times, this should be taken into consideration when interpreting results.
     This report summarizes extraction / preparation and analysis times and compares each with ALS recommended holding times (referencing USEPA SW 846, APHA, AS and NEPM) based on the sample container
     provided. Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.
     Holding time for leachate methods (e.g. TCLP) vary according to the analytes reported. Assessment compares the leach date with the shortest analyte holding time for the equivalent soil method. These are:        organics
     14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.
     Holding times for VOC in soils vary according to analytes of interest. Vinyl Chloride and Styrene holding time is 7 days; others 14 days.    A recorded breach does not guarantee a breach for all VOC analytes and
     should be verified in case the reported breach is a false positive or Vinyl Chloride and Styrene are not key analytes of interest/concern.
