Shallow aquifer water (30+ m depth) has been used for seasonal cooling of buildings at Stockton University, New Jersey, in an open loop system. High dissolved oxygen levels in a (semi-)confined aquifer led to iron hydroxide precipitation in wells after several years of operation resulting in the eventual failure and shutdown of the open loop system...

... the model was constructed with well grout and clay layer non-overlapping at the scale of the vertical grid (2 m). A portion of the grid in the +x, +y corner is shown in Fig. 6. Pressure at the top of the lower Cohansey at the end of two hours injection at 101 l/s total, as well as a cross-section detail through cold well 1, are shown in Fig. 7. Some material failure (non-linear shear) occurs both in the sand pack and in the clay layer adjacent to the sand pack. The non-linear strain is shown in strainèllipsoids' at failing element centers in Fig. 8, projected in plan view, and in cross section. The figures of the ellipsoids trace the strain as a function of angle. As the ...
