Quality Water Filters 4 You Posting Page
Friday, April 2, 2010
Color, taste, and odor are often the first clues consumers have that their tap water may not be as clean as they would like. What may surprise some people is that these issues may pop up at any time. It is incorrect to assume that any one of these problems must have been "there in the first place". Here are some points to consider when you find you have any of these problems with your tap water.
For Taste Problems:
If your tap water has a salty or brackish taste to it, it may be caused by high sodium levels in the water. If it has a alkali taste it may be due high levels of hardness, high levels of total dissolved solids, or a high alkalinity level. Metallic taste is often caused by low pH, high content of metal in the water or even corrosive water. Also, metallic taste can be caused by inorganic chemicals. For example, iron, copper, and zinc are all capable of producing metallic taste in tap water.
For Odor Problems:
If you have odor issues with your tap water, you may detect smells similar to rotten eggs or musty odors. You may also detect smells that resemble turned earth, grassy or fishy odors, and even odors that mimic vegetables.
Hydrogen sulfide is often the culprit in many odor-prone waters. Algae and bacteria are also known to cause odors as they are processed in the disinfection cycle. Hot water heaters may contain high levels of algae by-products as well.
Oily smells are most often caused by gasoline or oil in the water. This odor may present a high level of hazard and should be investigated at once.
For some groundwater sources, the odor of methane is common as the gas decomposes in the aquifer.
Any type of industrial chemical smell should be investigated at once and the water should not be used until the cause of those particular odors has been found.
Issues with Water Color:
Clean, safe water should be crystal clear. If you notice that your tap water has a milky look to it, it may be due to excessive air in the system, carbonate precipitation (that white scale you see on the walls of metal pipes coming loose), or it may be due to suspended solids coming in from either the distribution water pipes or pipes from within your home.
A blackish tint almost always results when reactions take place with manganese and iron. Slime bacteria may also be responsible for a blackish look to your tap water.
A yellow tint in your tap water may be caused by the presence of either humic or fluvic compounds, iron, and certain types of bacteria.
The common red tint is most often caused by dissolved iron or precipitated iron in the water. Some forms of bacteria can also cause red tinting to tap water.
The best ways to treat problems of taste, odor, or color is through water filtration, filtration through a carbon filter, water softening processes, chlorination, reverse osmosis, and in some cases, distillation. The type of water filter or filter process that will work best for you depends on the particular problem you have and the concentration and type of contamination that is in your tap water.
