Geochemical and physical measurements: meters/probes (pH, mV, Temperature,
Conductivity, Dissolved Oxygen (D.O.)), spectrophotometry (Fe(II),
NH4(T)), ion chromatography (Cl, SO4), IR-MS (dissolved inorganic carbon
(DIC), dissolved organic carbon (DOC), ICP-OES (P, Na, K, Ca, Mg, Si,
italisized values for Al and FeTotal), and ICP-MS (Al, Mn, Fe). LLC = limestone-
lined channel, S.D. = standard deviation, bdl = below detection limits,
