# Ra isotopes in groundwater wells. # W. Burnett and B.

Low yields on some of the shallow wells # were a result of reducing groundwaters attaching the MnO2 fibers. ========================= date_local year yrday_local ------------------------- 29-Jun-10 2010 180 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- DW4 -87.687 30.262 23 0 6.7 0.77 209 4.78 66.5 1.7 166 13.4 nd DW5 -87.686 30.263 22.5 0 18.5 1.4 660 12.7 151 1.04 492 17.7 nd ========================= date_local year yrday_local ------------------------- 28-Jul-10 2010 209 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- DW3 -87.657 30.275 22.7 0.1 5.52 0.76 304 8.39 113 5.69 333 15.1 nd DW4 -87.687 30.262 24.2 0 4.2 0.74 208 6.79 47.9 1.44 154 13.9 nd DW5 -87.686 30.263 23 0.1 16.7 1.55 558 9.93 157 1.11 438 19.2 nd TW10 -87.774 30.254 25.1 0.1 4.72 0.76 95.9 4.31 41.5 0.37 51.9 10.8 nd ========================= date_local year yrday_local ------------------------- 25-Jul-11 2011 206 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1 -87.693 30.255 27.7 3.8 2.21 0.24 23.8 1.19 12.2 0.25 25.2 2.52 nd TW1R -87.693 30.255 27.7 3.8 2.73 0.29 25.5 1.25 13.5 0.65 20.2 2.89 nd TW5 -87.725 30.254 27.5 0.2 1.93 0.22 49.4 1.44 22 0.6 39.7 3.44 nd TW5A -87.725 30.254 27 0.2 2.5 0.26 53.4 1.4 33.6 0.46 40.5 3.38 83.9 TW5B -87.725 30.254 27 0.2 0.94 0.16 3.8 0.23 5.42 0.15 5.45 3.13 nd TW5corr -87.725 30.254 27 0.2 2.98 0.31 63.7 1.67 40 0.55 48.3 4.03 nd TW5R -87.725 30.254 27.5 0.2 1.56 0.19 56.8 1.64 30 0.52 35.2 2.73 nd ========================= date_local year yrday_local ------------------------- 7-Sep-11 2011 250 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1 -87.693 30.255 27.1 4.7 4.04 0.41 29.1 1.3 17.4 0.27 18.8 3.37 nd TW5 -87.725 30.254 27.1 0.3 3.07 0.3 89.2 2.18 25.1 0.2 33.7 3.08 nd ========================= date_local year yrday_local ------------------------- 29-Nov-11 2011 333 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1A -87.693 30.255 21.7 4.63 6.18 0.52 50.3 1.16 37.4 0.97 47.2 2.85 43 TW1B -87.693 30.255 21.7 4.63 3.71 0.4 27.3 0.99 21.3 0.86 22.6 2.5 nd TW1corr -87.693 30.255 21.7 4.63 14.4 1.21 117 2.7 -87 2.26 110 6.63 nd TW4 -87.678 30.256 21.5 6.78 7.99 0.66 59.4 1.33 93.3 0.84 39.9 2.9 nd TW5 -87.725 30.254 22.4 0.2 1.63 0.24 45.3 0.9 19.2 0.62 24.1 2.71 nd TW7 -87.786 30.245 21.6 0.11 1.1 0.25 10.9 0.56 2.46 0.07 11.2 2.83 nd ========================= date_local year yrday_local ------------------------- 6-Mar-12 2012 66 ========================= site lon lat temp sal Ra223 err_Ra223 Ra224 err_Ra224 Ra226 err_Ra226 Ra228 Ra228_err Yield ------------------------- TW1 -87.693 30.255 19.6 1.85 5.05 0.49 34.8 1.25 17 0.43 19 2.39 nd TW1A -87.693 30.255 19.6 1.85 4.01 0.41 27.4 1.14 13.5 0.22 15.8 1.89 44.4 TW1B -87.693 30.255 19.6 1.85 2.35 0.34 18.7 1.13 7.52 0.13 6.65 1.8 nd TW1corr -87.693 30.255 19.6 1.85 9.04 0.92 61.7 2.57 30.5 0.5 35.7 4.26 nd TW3 -87.67 30.255 20.1 2.5 3.78 0.45 40 1.21 27.3 0.23 19.1 2.35 nd TW3A -87.67 30.255 20.1 2.5 2.46 0.35 33.5 1.15 22.8 0.09 19.7 2.27 33.8 TW3B -87.67 30.255 20.1 2.5 1.66 0.33 20.9 1.17 15.1 0 10.6 1.91 nd TW3corr -87.67 30.255 20.1 2.5 7.27 1.04 99.1 3.4 67.4 0.27 58.2 6.71 nd TW4 -87.678 30.256 18.9 8.81 6.47 0.67 60.2 1.46 114 1.06 46.8 3.53 nd TW4A -87.678 30.256 18.9 8.81 14 1.11 105 1.94 197 3.46 86.1 4.55 84.1 TW4B -87.678 30.256 18.9 8.81 2.48 0.52 22.3 1.22 31.4 0.75 10 3.15 nd TW4corr -87.678 30.256 18.9 8.81 16.7 1.32 125 2.31 235 4.11 102 5.41 nd TW5 -87.725 30.254 20.6 0.2 2.73 0.27 48.4 1.24 27.9 0.23 41.3 1.97 nd TW5A -87.725 30.254 20.6 0.2 2.64 0.36 43.1 1.51 26.5 0.35 37 2.53 86.8 TW5B -87.725 30.254 20.6 0.2 0.42 0.09 2.45 0.24 3.49 0.9 8.4 2.19 nd TW5corr -87.725 30.254 20.6 0.2 3.04 0.41 49.6 1.74 30.5 0.4 42.6 2.91 nd TW6 -87.725 30.255 21.4 0.07 3.54 0.39 38.2 1.3 32.5 0.86 43.7 2.9 nd TW6A -87.725 30.255 21.4 0.07 3.21 0.4 35.3 1.11 24.4 0.52 40.1 2.62 15.6 TW6B -87.725 30.255 21.4 0.07 2.24 0.35 24.9 1.12 20.6 0.6 26.1 1.97 nd TW6corr -87.725 30.255 21.4 0.07 20.6 2.56 226 7.11 156 3.33 257 16.79 nd TW7 -87.786 30.245 20 0.1 0.88 0.17 9.13 0.61 1.98 0.59 5.05 1.33 nd TW7A -87.786 30.245 20 0.1 0.8 0.18 8.11 0.6 1.35 0.04 5.74 1.5 100 TW7B -87.786 30.245 20 0.1 B.D.
