Data Dictionary: Terms and symbols commonly found in the data files are alphabetically listed and defined here. NOTE: All measurements of chemical constituents in surface water and bottom sediments are complemented by a remark data field. This field will either have a less than (<) symbol or it will be blank. Less than (<) = measured amount was less than reporting limit; blank = measured amount was above reporting limit.This is shown for silver below but is omitted from the rest of this data dictionary. NOTE2: Missing values in the dbase file are represented as -99, -997, or -9. ag: Silver, dissolved (ug/L as Ag). ag.r: Silver, dissolved (ug/L as Ag), remarks. This field is either blank or it has a less than (<) symbol: < (less than) = measured amount was less than reporting limit. blank = above reporting limit. ag.bm: Silver, total in bottom material (ug/g as Ag). ag.bm.r: Silver, total in bottom material, remarks. This field is either blank or it has a less than (<) symbol: < (less than) = measured amount was less than reporting limit. blank = above reporting limit. ag.t: Silver, total (ug/L as Ag) agyanal: Analyzing agency PRIV = Water sample analyzed by Private Lab SJVDP = Water sample analyzed by San Joaquin Valley Drainage Program USGS = Water sample analyzed by United States Geological Survey WYDOA = Water sample analyzed by Wyoming Department of Agriculture agycol: Collecting agency USGS = Water sample collected by United States Geological Survey SDWRI = Water sample collected by South Dakota Water Resources airt: Temperature, air (deg C) al.bm: Aluminum, total in bottom material (ug/g as AL). al.t: Aluminum, total (ug/L as Al) alk: Alkalinity, titration to pH 4.5, field, (mg/L AS CaCO3) alk.co3.it:Alkalinity, carbonate, incremental titration, field (mg/L as CaCO3) alk.dis.it:Alkalinity, total dissolved, field (mg/L) alk.lab: Alkalinity, titration to pH 4.5, laboratory, (mg/L as CaCO3) alk.it: Alkalinity, carbonate, incremental titration, field (mg/L as CaCO3) alk.ww.fe: Alkalinity, water, whole, total, fixed endpoint titration, lab, mg/l as caco3. alk.ww.gt: Alkalinity, water, whole, gran titration, field, as caco3, mg/l altitude: Altitude of data collection site, in feet above msl area: Abbreviated name identifying NIWQP study area as: Arsenic, dissolved (ug/L as As) as.t: Arsenic, total (ug/L as As) as.bm: Arsenic in bottom sediment (mg/kg dry weight) au.bm: Gold in bottom material (ug/kg as AU) b: Boron, dissolved (ug/L as B) ba: Barium, dissolved (ug/L as Ba) ba.bm: Barium, total in bottom material (ug/g as Ba) background: C = Site is either within or downgradient from irrigated areas within the study area R = Site is upgradient of irrigated areas within the study area baro.p: Barometric pressure, in mm of Hg basin: Indicates drainage basin type O = Lakes in study area are flow through M = Lakes in study area are mixture of flow-through and terminal C = Lakes in study area are terminal ba.t: Barium, total (ug/L as Ba) be: Beryllium, dissolved (ug/L as Be) be.bm: Beryllium, total in bottom material (ug/g as Be) be.t: Beryllium, total (ug/L as Be) bi.bm: Bismuth, total in bottom material (ug/g as Bi) br: Bromide, dissolved (mg/L as Br) b.t: Boron, total (ug/L as B) b.xw.bm: Boron, hot water extractable, in bottom material, (ug/L as B) ca: Calcium, dissolved (mg/L as Ca) ca.bm: Calcium, recoverable from bottom material, dry wt.
