Metal Concentrations

The following samples were analyzed for various metals. All results are reported in units of parts per million (ppm). Any result that was below the instrument detection limit is designated by '<LD', and any result that was detectable but not quantifiable (e.g., lower than the limit of quantitation) is designated by 'DNQ'.

TDS, Alkalinity, and Salt Concentrations

The following samples were analyzed for total dissolved solids (TDS), alkalinity, and various [[Salts Analysis|anionic salts. All results are reported in units of parts per million (ppm). Any result that was below the instrument detection limit is designated by '<LD', and any result that was detectable but not quantifiable (e.g., lower than the limit of quantitation) is designated by 'DNQ'.

Notes

  1. Samples were not analyzed for aluminum prior to June 2014.
  2. Alkalinity is reported as ppm CaCO3 equivalents.
