Metal Concentrations Summary

The following samples were analyzed for various metals. All results below are 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 Summary

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