After a long time spent searching I finally found a site that explained the problems with Zimbabwe's water supply. I had already known that there was a weed in it that was causing problems, but I did not know what exactly this weed was. http://www.scienceinafrica.co.za is the site that I got the information about. (full hyperlink at end) It explains about what water hyacinth is and how it is assumed to have been started. Water hyacinth is an underwater weed that grows at an abnormally high rate. It grows to about one meter long and floats on the surface of the body of water it may be occupying. "Environmentalists in Harare blame the spread of the weed on the discharge of effluent, particularly raw sewage, into lake Chivero." This was a useful statement because I could connect the economy to the weeds. Without money for proper sewage treatment it gets disposed of improperly and this leads to the rest of the problems. Environmentalist groups are trying different ways to kill the weed but no ways prove to be very effective.
If anybody is interested this is the link to the site page: http://www.scienceinafrica.co.za/2005/april/hararewater.htm
