If contaminated water is found in Well A, is it more likely to have come from the waste pit or the pasture? Why?
The question is based on Figure 25-3, a map of a hypothetical landscape with an effluent stream flowing from northeast to southwest. Water table contours are drawn at 2-foot intervals and flow lines show the direction of groundwater movement at the top of the zone of saturation. The waste pit in the north was dug down to a depth just slightly above the water table in that location. A fenced pasture for grazing livestock is in the east. Two wells are shown, and the locations of three water quality sampling sites along the stream are indicated. What will be an ideal response?
An air mass is a large region of air, typically hundreds or thousands of square kilometers, with relatively uniform characteristics of temperature and humidity
