How to Filter Pond Water for Human Consumption
- 1). Buy a water filter or chemical purification tablets. Most outdoor retailers offer water filtration systems or purification tablets. Some filters are pumps you fill with water and pump through the system into a clean container. Purification tablets are made of chemicals designed to kill harmful toxicants--simply drop one into a container of water. If you buy a filter, look for one with a pore-size efficiency of less than 0.4 microns; this will remove almost every harmful toxicant.
- 2). After you have run the pond water through your portable filter or used a chemical purification tablet, clear a small area of debris and build a fire capable of boiling a small pot of water.
- 3). Pour the water into a clean pot and boil the water for at least 10 minutes. While many filters and chemical purification tablets remove most of the harmful toxicants, boiling the water thoroughly will remove any that the filter or tablets miss. After 10 minutes, remove the water from the heat, allow it to cool and drink up.
