  1. NY Water Sentinels: Data contributions to Shale Network database 10/04/2013

  2. NY Sentinels • Location: New York State • Contact: Jessica Helm (Sentinels) and Julie Vastine (ALLARM) • Number of sites sampled: 69 • Analytes: conductivity, TDS, strontium, and barium • Goal: To collect water quality data in areas vulnerable to horizontal drilling and hydrofracking from July, 2012 through March, 2013.

  3. Shale Network locations (black/blue rectangles) plotted with NY Sentinels sample locations (green) as of 10/04/13

  4. NY Sentinels sampling locations for data in Shale Network database as of 10/04/13

  5. NY Sentinel data plotted with U.S. Geological Survey (NWIS) surface water data for specific conductivity in New York (as of 10/4/2013) NWIS; mean= 367.0 uS/cm standard deviation= 2339.7 uS/cm NY Sentinel; mean= 302.9 uS/cm standard deviation= 215.7uS/cm

  6. NY Sentinel data plotted with U.S. Geological Survey (NWIS) surface water data for barium in New York (as of 10/4/2013) NWIS; mean= 30.9 ug/l standard deviation= 21.4 ug/L NY Sentinel; mean= 30.22 ug/L standard deviation= 27.4 ug/L

  7. NY Sentinel data plotted with U.S. Geological Survey (NWIS) surface water data for strontium in New York (as of 10/4/2013) NWIS; mean= 338.1 ug/l standard deviation= 750.9 ug/L NY Sentinel; mean= 42.63 ug/L standard deviation= 42.87 ug/L

  8. Conclusions • NY Sentinels are providing conductivity, TDS, Ba, and Sr data to the public dataset for the northeast in areas of gas development • Dissolved Ba and Sr concentrations for the Sentinels’ 69 sites are well within the mean for Ba and Sr measured and reported by the U.S. Geological Survey as NWIS data since 1960 • The Sentinels data will be useful to document background concentrations if unconventional gas wells are drilled in NY
