By and large it is the man-made pollutions of waters that get the most attention, and perhaps rightfully so. But what is also important is the overall contamination, or natural quality of water that will help determine the treatments necessary to make a water safe for public consumption.n example of a point source of water pollution is a pipe from an industrial facility discharging effluent directly into a river. An example of a nonpoint-source of water pollution is when fertilizer from a farm field is carried into a stream by rain (i.e. run-off).

New World vultures have weak talons but a strong sense of smell. They are able to locate carcasses with their sense of smell alone, but Old World vultures must rely on their excellent vision to detect carcasses. There are only 2 species of condors, the California Condor and the Andean Condor. Both species are relatives of New World vultures, but are not closely related to Old World Vultures. The 2 species of condors are larger than other New World vultures such as the Turkey Vulture and Black Vulture. None of the Old World vultures, regardless of size, is called a condor. Source(s):
