Q1: I was wondering if we have any information about the capacities of the wells in either town. With the information we have now, the best we can do is assume that it is okay to draw the town's needs evenly divided between each of the wells. I assume we can't just stick a pump in one of the wells and draw out as much water as we would like without depleting the water source. Any information on this would be great. A: We have little to no information on the state of the aquifer. In the absence of better data, it would be best to focus more on the water quality (salinity) issues than potential water quantity issues; assume that there is sufficient water to supply each household with 200 liters/day between all the sources and that all wells tap into the same aquifer and refill at the same rate. Q2: is there a particular health hazard which the water is currently causing? If so what is the hazard and which impurity is causing it? A: We have no clinical data on health issues related to salinity, though hypertension and complications with diabetes are generally associated with high salinity content of drinking water. Also see Rays answer. For the purposes of this assignment, it is best to focus on the salinity and to assume that it has negative health impacts....
