Water Treatment for Contamination, Hardness, Odors, Sediment, Etc: choices of systems, recommendations
Our list of water treatment articles is at the end of this page. Here we discuss water treatment methods and we also include water testing and water correction measures warnings for home owners and especially for home buyers when certain conditions are encountered, with advice about what to do when these circumstances are encountered.
If you are looking for portable or emergency use water purification methods, see DRINKING WATER - EMERGENCY PURIFICATION for a discussion of various methods used to purify water for hiking, campling, and emergency use as well.
While we distinguish between having to treat water because it is not potable, and wanting to treat drinking water because of an aesthetic concern like odor, taste, smell, or staining, it is often the case that the equipment used for one purpose can also address the second set of concerns.
Here we are discussing water treatment, not water testing. See WATER TEST CHOICES & WATER TEST FEES for choices of water tests and our advice about choosing among them.
If community or private wells are back in operating and providing water, do not assume that the water is sanitary and ok to drink until responsible authorities have said so. Even then, local water pipes in a building may be unsanitary and additional cleaning or disinfection may be needed. See WELL CHLORINATION SHOCKING PROCEDURE and See WATER TESTS, CONTAMINANTS, TREATMENT for advice on using a private well for drinking water.
Pros/Cons: Advantages and Problems with Various Types of Water Treatment Equipment for Bacterial or Bacteriological Contamination
Water filters are great for removing sediment or odors - aesthetic considerations. But we suspect any mechanical or charcoal water filter is either unreliable or short-lived. OPINION: For pathogens or bacteria this is a poor choice of water treatment. We discuss water filters for sediment and odors below.
See WATER FILTERS, HOME USE for details about water filter installation, use, and maintenance. Also see the following related articles:
Drinking water should be tested periodically, at least annually, especially if there is a known contamination issue - to make sure that the well has remained sanitary, or to make sure that the treatment equipment is working properly. Perhaps also to get lucky and find that treatment is no longer needed.
A minimum test is to collect a sample of treated water for this purpose. IF you also test water collected ahead of the treatment system you can confirm what treatment is needed.
Water treatment chemicals can be highly toxic or caustic and should be kept out of reach of children.
List of Principal Methods Used to Purify Contaminated Drinking Water when Camping or in an Emergency
Basic water purification procedures that can be used in an emergency are described just below. If community or private wells are back in operating and providing water, do not assume that the water is sanitary and ok to drink until responsible authorities have said so. Even then, local water pipes in a building may be unsanitary and additional cleaning or disinfection may be needed. See WELL CHLORINATION SHOCKING PROCEDURE and See WATER TESTS, CONTAMINANTS, TREATMENT for advice on using a private well for drinking water.
