Analysis Holding Time Compliance
The following report summarises extraction / preparation and analysis times and compares with recommended holding times. Dates reported represent first date of extraction or analysis and precludes subsequent
dilutions and reruns. Information is also provided re the sample container (preservative) from which the analysis aliquot was taken. Elapsed period to analysis represents number of days from sampling where no

extraction r digestion is involved or period from extraction ; digestion where this is present. For composite samples, sampling date is assumed to be that of the oldest sample contributing to the composite. Sample date
for laboratory produced leachates is assumed as the completion date of the leaching process. Outliers for holding time are based on USEPA SW 846. APHA, AS and NEPM (1999). A listing of breaches is provided in
the Summary of Outliers.

Holding times for leachate        methods (excluding elutriates) vary according to the anatytes being determined on the resulting solution. For non -volatile analytes, the holding time compliance assessment compares the
leach dale. with the shortest anatyte holding time for the equivalent soil method. These soil holding times are: Organics (14 days); Mercury (28 days) & other metals (180 (lays). A recorded breach therefore does not
guarantee o breach for all non-volatile parameters.
