PURE WATER FROM LAKES
Fresh water lakes are numerous throughout North America. These lakes are huge reservoirs of pure water, used for our consumption and agriculture. Because our population and industry, most of our inland lakes still require purification before we drink the water. As with any water treatment, lake water should be first filtered then passed through a purification sieve to remove micro fine particles and pathogens.
A lot of lake side residents use lake water as their main source of potable water but as mentioned it still requires filtering and purifying before use.
Another simple, more effective way of pre-treating lake water is to dig a well close to the lake and allow the water to pass through the sand or rock into the shallow well. Two things happen when you use this water pre-treatment approach. The most obvious is filtering. The not so obvious advantage is the micro biotic action of the sand or ground before the water reaches the well. This lake well still has to be prepared or conditioned before regular use.
It would be a shame not to use or lake water for consumption. There are however, exceptions:
1) If the water is polluted with industrial waste.
2) If there are heavy metals in the water supply.
3) If the water has been deemed poisonous or unsafe for human use.
Yes there are always ways to clean badly polluted water, be it lake water or otherwise.
It comes down to time and money. For nearly fool proof water cleaning please see "solar still" or "natural desalination".
