3 Negative values denote readings below lab detection levels.
4 ACZ Lab Qualifiers: U - Analyte was analyzed for but not detected at the indicated MDL.
H - Holding time exceeded; pH is a field test with an immediate hold time.
B - Analyte conc detected at a value bet method detection limit (MDL) and practical quantitation limit (PQL).
