1. THMs and Chlorine – chlorine is used by municipal systems to eliminate bacteria, however recent studies show that chlorine can react with organic material in water to form chemicals called Trihalomethanes (THMs).
One of these THMs is chloroform, a suspected cancer-causing agent. THMs have also been linked to miscarriages. Our product recommendations to remove chlorine from your water supply include drinking water filters, reverse osmosis and shower head filters.
2. Lead – Lead in drinking water can cause serious health problems. At low levels, reduced birth weight and premature birth, delayed mental and physical development, and impaired mental abilities in children may result. At high levels of exposure, anemia, kidney damage, and mental retardation can occur. Recommended water treatment technologies.
3. Cysts – Recent studies indicate that Cryptosporidium cysts are present in up to 97 percent of surface waters in the country and that 23 million Americans reside in communities that do not filter municipal drinking water that comes from surface sources. (Journal of Water & Soil Conservation)
Giardia lambila, a protozoan familiar to hikers who have sipped from clear mountain streams, causes the intestinal disease giardiasis.
Cryptosporidiosis is a disease caused by the parasite Cryptosporidium parvum, which as late as 1976 was not known to cause disease in humans, according to the Centers for Disease Control and Prevention.
Spread largely by fecal contamination, the diseases are transmitted through direct contact with infected stools, or by drinking water contaminated with Cryptosporidium or Giardia oocysts, the infectious egg-like forms of the parasites. The most vulnerable are the elderly, people with suppressed immunity and transplant patients.
Recommended water treatments: It is important to decide if there is a taste issue along with the cysts or not. If there is not a taste issue we recommend a POE (point-of-entry) high capacity Poly-Pleated™ 20 micron absolute, sediment filter. For POU (point-of-use) the Doulton Ultracarb filter, a Water Factory SQC4 Reverse Osmosis unit or a Westbend Distiller.
4. Pesticides and Herbicides – Often toxic and associated with a wide range of health problems. Pesticides and herbicides readily leach through soil in to ground water supplies and directly in to water systems from surface run-off. Recommended water treatment technologies.
5. Industrial Chemicals – Although many governments are imposing fines on manufacturers for chemical spills and misuse there is still widespread water contamination. Many industrial chemicals, if ingested, may cause increased risk of cancer and other illnesses. Some of these industrial chemicals include polychlorinated biphenyls (PCBs), polynuclear aromatics (PNAs), and volatile organic chemicals (VOCs), such as TCE, benzene, and carbon tetrachloride.Recommended water treatment technologies.
6. Large particulate contaminants and sediments – asbestos fibers, dirt, and other particles are often found in drinking water.
This is a common problem with well water. It is important to decide if taste and color is a complaint in addition to cysts.
If there is not a taste issue we recommend a POE (point-of-entry) high capacity Poly-Pleated™ 20- micron absolute, sediment filter. For taste and/or other complaints please check our recommended water treatment technologies.
7. Hard Water deposits – the hardness minerals calcium and magnesium are the cause of hard water in some 85% of all homes in America. Hard water is expensive and has many associated disadvantages however removal is simple with our recommended cation exchange water softener.
8. Iron Staining – there are two types of iron: Soluble and insoluble. Soluble is clear in running water but settles out as black or rust-colored particles.
If the sediment comes into contact with air it produces iron staining. Soluble iron cannot be filtered out of water but it can be reduced with the use of our recommended cation exchange water softener. Insoluble iron is visible in running water as rust colored particles.
These particles can be successfully filtered out using a cartridge filter or a backwashable media filter, the most commonly used is a Birm filter.
9. Nitrates – In addition to lead, nitrates can also enter water following treatment. The presence of nitrates in water suggests the possibility that human and/or animal wastes or fertilizers used in agricultural or gardening activities are entering the system.
Faulty cross- connections with wastewater piping are often the source of nitrate contamination when it occurs in treated water. Nitrates are of special concern to young children and women of child-bearing age.
Excessive levels of nitrates have been linked to the occurrence of “blue baby” syndrome. We recommend the use of a softener with a special nitrate reducing resin added to correct this problem.
10. Radon – Although you can’t see it, smell it, or feel it, the U.S. Environmental Protection Agency (EPA) estimates that nearly every home in America has some level of radon in the air.
They say most homes will not have levels high enough to require reduction measures, but a significant number will. Of the 75 million homes in the U.S., the EPA estimates that 10 percent of those have radon levels above the current guidelines.
Radon, a radioactive gas, breaks down rapidly into radioactive decay products. It becomes extremely dangerous when these decayed products become lodged in a person’s lungs or respiratory tract.
When this radon in a person’s home undergoes this type of decay, the gas is considered deadly, and inhaling too much of it may cause cancer.
The EPA says that radon is the second leading cause of lung cancer, and estimates that 20,000 cases can be attributed to radon. For those persons who are smokers and are exposed to high radon, the risk is greater because smoke attracts the radon particles that are inhaled by a smoker.
Of the estimated 20,000 radon-related cancer cases, 15,000 are smokers. Recommended water treatment technologies.
11. Fluoride – this is a naturally-occurring constituent of some water supplies. However levels in excess of 2.0 PPM (the EPA standard) can cause tooth discoloration.
More seriously, long term exposure to drinking water with more than 4.0 PPM of fluoride can cause skeletal fluorosis, a debilitating and crippling bone disorder resembling osteoporosis. Recommended water treatment technologies.
12. Odors – the two most common odors reported in drinking and bathing water are chlorine and “rotten eggs”. The rotten egg smell is hydrogen sulfide, a gas produced by harmless bacteria.
Both of these unpleasant odors can be removed with the installation of a backwashable water filter containing a specialized activated carbon, specific to your water conditions.
To determine which filter and media is most suitable for your water requires analysis of your water supply.
