Document Summary
Tce transport to woburn wells g and h in massachusetts from 1960 1986. Hydrogeology: how water moves through rocks underground. Moved underground and dissolved into drinking water. Industrial factories: grace, unifirst, olympia, beatric, nep, surrounding aberjona river. Water getting pumped out for use in factors (g and h) Located in the middle of 5 factors, near river. Water penetrates through hard rock more difficultly. Major spill was just north of the tannery wells, which were using water for industrial purposes became highly contaminated. If the pumping wells were not present or were inactive, groundwater would flow towards the river, because the river is where water table meets land surface. When they were turned on, they pulled toxins towards them. Pumping wells create an underground pressure gradient which pulls water towards themselves. The direction of groundwater flow is determined by hydraulic head.
