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'.

- A site denoted by "dropped" means that this sampling point will no longer be visited for field or lab data collection. Reasons for dropping a sampling point may include: redundancy with other sites; site is no longer accessible; land use changes may have removed the site (e.g., new road, culvert, etc.). This site will not appear in future data reports unless reactivated.
- Samples were not analyzed for aluminum prior to June 2014.
- Alkalinity is reported as ppm CaCO3 equivalents.
