| Analysis Method | Theis |
| Comments | T and S values are averaged from 3 observation wells that were close to the pumping well using the Theis Method. Cooper Jacob Method resulted in an average T of 15,076 and S of .0005 The Beaufort and Castle Hayne pumping wells for the test were right next to each other and the same LL coordinate is given for both in the GMA report entitled Onwasa TW Completion Report Dec. 7, 2012 |
