Field Data Summary Report

Below is a field data summary report for this site, including the average and standard deviation values for each measured parameter. Collector initials are explained here.

Date Collector Time pH TDS (ppm) Cond. (µS) Temp. (C°) Comments
2011/06 JW 11:15 7.50 328 663 14.8 very low levels
2011/09 JW 9:34 7.35 273 543 18.2 low flow
Average values 7.42 300 603 16.5

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'.

Date Ca Mg Fe Mn Al[1] Sr Pb As Hg Cr Ba Cd
2011/06 75.9 7.8 DNQ 0.045 0.226 <LD <LD <LD <LD 0.052 <LD
2011/09 72.7 11.0 <LD 0.073 0.206 <LD <LD <LD <LD 0.052 <LD
Avg. ± std.dev. 74 9 0.1 0.216 0.052

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'.

Date TDS Alk.[2] F Cl Br NO3 PO4 SO4
2011/06 547 116.21 0.13 67.02 0.455 4.81 0.33 125.13
2011/09 363 85.67 0.09 35.09 0.296 3.39 0.34 135.49
Avg. ± std.dev. 455 101 0.11 51 0.38 4.1 0.34 130

Notes

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