Data Set Methods
Lab Analysis: 

pH - Electrometric with combination electrode
Conductivity - Conductivity bridge
Cl - up to 1989 by automated colorimetric analysis (thiocyanate); after 1989 by liquid chromatography with conductivity detection
NO3-N - up to 1989 by automated colorimetric analysis (Cd-Cu reduction); after 1989 by liquid chromatography with UV or conductivity detection
SO4-S - Liquid chromatography, conductivity detection
Na, K, Mg, and Ca - up to 1994 by atomic absorption spectroscopy; after 1994 by ion chromatography with conductivity detection
NH4-N - automated colorimetric analysis (phenolhypochlorite)
PO4-P - automated colorimetric analysis (molybdate blue)
DOC - up to 1998 by persulfate oxidation (McDowell et al. 1997); after 1998 by high temperature catalytic oxidation
DIC - by syringe stripping and infrared spectroscopy (Stainton 1973).
TDN - prior to 1998 by persulfate oxidation and automated colorimetric analysis; after 1998 by high temperature catalytic oxidation with chemiluminescent detection
TDP - by persulfate digestion followed by automated colorimetric analysis
SiO2 - automated colorimetric analysis (molybdate blue)
DON - by difference (TDN - NO3-N - NH4-N)
