Desalting the sea.

Oak Ridge National Laboratory,, . Videocassette (VHS)(ca. 25 min.) : sd., col. 1/2 in. , Confident that an endless supply exists in lakes, rivers and streams, man has polluted and wasted water in many parts of the world. Elsewhere because his land has become parched, withered and scorched by drought man has packed up his belongings and migrated thousands of miles to relieve his thirst. Of all the water on earth more than 97 percent is in the ocean and not fit to drink and too salty for irrigation. Within twenty years man's demand for water will double. In many areas the most economical step lies in desalting the sea.

Water purification.

. videocassette (VHS)(10 min.) : , Wherever you are in the field, if you're not sure the water is safe for drinking, purify it first otherwise you may get typhoid, cholera, or dysentery. This film shows various sources of water at advanced phases and how it can be made safe and drinkable. Surface water such as that in rivers, lakes, ponds and streams is obviously the most easily contaminated but necessary treatment can be quickly determined and accomplished. Groundwater in wells and natural springs though you might think it pure must nonetheless be treated since it is subject to contamination by seepage. Melted snow contains the same type of impurities as surface water so it too must be purified before drinking. Even rain water gathered in natural or man-made collecting places picks up germs or decaying vegetation that gives it a bad odour or taste makes it dangerous. No matter where it comes from or how good it looks, treat it first before drinking it.
