Notes:
'Sample container requirements shown for leachate samples are applicable to field collected water samples, based on the
approximate volumes needed to complete the listed analyses for a particular preservative type. Actual container sizes used during
the MWMP tests will be determined by the laboratory.
2Units in pg/L, unless otherwise noted.
3Acid-Base Accounting consists of reporting the following parameters:
-Total Sulfur -Residual Sulfur
-Water - Extractable Sulfur -Acid Potential
-HCl - Extractable Sulfur -Neutralization Potential
-HN03 - Extractable Sulfur -Net Acid Generating Potential (NAG or static peroxide test)
°NA = not applicable.
5Analysis should be performed as soon as possible, or immediately after sample collection.
eReporting limit will be spec to the electrode instrument utilized by the laboratory.
'Radiochemistry samples have a sample specific Minimal Detectable Concentration (MDC) calculated as the reporting limit. The
MDC is affected by counting time, sample volume, TDS concentration, and instrument background.
