which of the following would be an example of point source water pollution - -factory
effluent
-when sewage contaminates a body of water, it can lead to a lower dissolbed oxygen level
in the water. this is because - -the sewage has put a high BOD on the water
-the world health organization estimates that ___of the world's population does not have
access to sufficient supplies of safe drinking water - -1 out of every 6
-match the following steps in the sewage treatment process:
1-biological
2-chemical
3-mechanical - -1-bacteria break down 85-90% of organic matter
2-chlorine, ozone, or ultraviolet light are used
3-solid waste materials settle out

-particulate matter
-a thermal inversion causes severe pollution events thermal inversions- - -occur when a
warm inversion layer traps emissions that then accumulate beneath it
-which of the following statements about stratospheric ozone depletion is correct - -ozone
