Study_Abstract: Within the Butler Farms/Oak Creek Village study neighborhoods, the existing condition of Tributary 7 (Potash Brook) has been evaluated over the last two project years (2004 and 2005) using a combination of surveys, water sampling, and continuous monitoring efforts.  The purpose of this effort is to determine the effectiveness of future BMPs that might be implemented or to assess other future changes in the system.  This file contains the laboratory results from stream water samples collected above (T7SW1) and below (T7SW2) the study neighborhoods during storm events.  
Study_Site_Location: Tributary 7, Potash Brook - South Burlington, Vermont 
Study_Methods/Experimental_Design: see variable descriptions 
Study_Sampling_Frequency: Grab samples were collected prior to the ISCO autosampler installation, and on an ad hoc basis for comparison to the composite ISCO sample results. Composite samples were taken by an ISCO model 6712c autosampler with a variable collection frequency based upon stream discharge.
Study_Variable_Descriptions: "Sampling Date" = mm/dd/yy of the sampling event | "Monitoring Site" = sampling location either above (T7SW1) or below (T7SW2) the study neighborhoods | "Sampling Method" = stream water sample collection method by either hand ("grab") or using a programmed ISCO 6712c autosampler ("ISCO").  Grab samples were collected at a single point during a storm event, as noted in the "Notes" field.  ISCO samples are composite, and are comprised of many sub-samples collected during the entire storm event. | "E. Coli" = concentration of Escherichia coli, an indicator organism commonly used to estimate bacteria levels, in units of MPN/100 ml, or most probable number of colonies per 100 ml of water; detection limit is 1 MPN/100 ml  | | "TSS" = concentration of total suspended solids in units of mg/L; detection limit is 2 mg/L | "Conductivity" = electrical conductivity in units of umho/cm  | "pH" = a measure of hydrogen ions in solution and thus the aciditiy or alkalinity; in standard units | "Total_P"  = concentration of total phosphorus in units mg/L; detection limit is 0.01 mg/L | "Nitrite_N" = concentration of nitrite (NO2-), an inorganic form of nitrogen, in units mg/L; detection limit is 0.020 mg/L | "Nitrate_N" = concentration of nitrate (NO3-), an inorganic form of nitrogen; detection limit is 0.020 mg/L | "TKN" = concentration of total kjeldahl nitrogen, which is the sum of organic nitrogen and ammonia, in units mg/L; detection limit is 0.080 mg/L | "Cadmium" = concentration of cadmium in mg/L; detection limit is 0.003 mg/L | "Chromium" = concentration of chromium in units mg/L; detection limit is 0.010 mg/L | "Lead" = concentration of lead in units mg/L; detection limit is 0.002 mg/L | "Mercury" = concentration of mercury in units mg/L; detection level is 0.001 mg/L | "Nickle" = concentration of nickle in units mg/L; detection limit is 0.020 mg/L | "Zinc" = concentration of zinc in units mg/L; detection limit is 0.020 mg/L | "Notes" = sampling notes
