Hello. Did your pumping test gives you also the drawdown of the pumping curves ? You should look at that before deciding the exact depth. The data you provides are only the characteristics of the well but not the result of the pumping test. I cannot really tell from these information only. Also please check if there are other borehole close by, in that case you should do the pumping test while other well are operating as it may influence on your aquifer. Check this drawing it explains what you need to know https://www.google.fr/search?q=pumping+test&ie=UTF-8&oe=UTF-8&hl=fr-fr&client=safari#imgrc=vsAblASPhUIlmM%3A.
