Sites are located in these Truckee Meadows waterways: Whites- upper & lower, Thomas-upper & lower, Steamboat Creek and North Truckee Drain. Samples are taken quarterly by agency staff from the Monitoring Subcommittee and analyzed at the TMWRF lab. Values less than the reporting limits are non-zero estimated values to simplify mathematical manipulation of the data. Minimum Test Reporting Limits (mg/l) are: Total-P 0.01, NH3-N 0.02, NO3-N + NO2-N 0.005, TKN 0.1, TSS 2, TDS 2 Analytical Method: DO, pH, Temp, Electrical Conductivity, NO3-N, TKN, Total N, Flow, Total P, TDS, TSS
The Sample Analysis Plan was updated in late 2010, and implemented in 01/2011. Both documents are available online. Due to a change in reported analytes, the data are now viewable as two sets.
Reporting Limits for Sampled Constituents: Total Coliform -- 1 mpn/100 mL E.coli -- 1 mpn/100 mL Turbidity -- 0 NTU Total Organic Carbon (TOC) -- 1.0 mg/L ** See attached PDF for specifications and limits of water quality parameters collected in the field with YSI 556 multimeter. (Temperature, Conductivity, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), pH, Oxidation-Reduction Potential (ORP). ** Please note: pH readings do exhibit some outliers due to malfunctioning pH probe. Analytical Method: Total Coliform & E. coli by MPN, TOC, turbidity. 2005-2008.
