Notes:

All Fecal and urine samples shall be reported in compliance with ANSI N13.30, Section

4.2 reporting requirements.

For all water analyses: methods used for analysis must be from approved methods listed in Title 40, CFR, Part 141.25 and 141.26 for Drinking Water Compliance. Methods must be specified and provided for review. Method substitutions must be approved prior to analysis.

All soil analyses for uranium and uranium ratios shall be prepared using a complete dissolution method to include hydrofluoric acid digestion. Preparation methods using a leach method will not be acceptable for these parameters and will be reanalyzed at contractor expense. Specify if a separate additional cost is required.

Detection Limits are highly matrix dependent; however, samples will be counted for the maximum count time to reasonably achieve specified detection level requirements.

Other isotopes of the same technologies may be added on a case by case basis with prior coordination between the contract lab and APHC (Prov).
