we are the best aquaguard service center in Chennai. The 100% safe water in this world is very impratical. So what are the contaminants are found in drinking water? Let us see what are impurities and how to overcome from the that.
The source of the contaminant is rock and soil leaching. This will Highly risk for dialysis patients
Aluminum is regulated in public drinking water with a recommended Secondary Maximum Contaminant Level (SMCL). SMCL’s are used
when the taste, odor, or appearance of water may be adversely affected.
In this case, the EPA and WHO agree that aluminum above 0.1 ppm may impact color but recognize that level may not be appropriate for all water supplies.
US EPA encourages utilities to maintain levels below 0.05 ppm, but recognizes the need to be flexible in this case because of the usefulness of Aluminum salts in the coagulation process.
WHO’s guideline of no more than 0.2 ppm is based on the importance of Aluminum as a coagulant and that all municipal systems should be able to keep treated water below this value.
Studies linking Aluminum in drinking water to human health issues have been inconclusive.
Likely the most famous bad guy, this heavy metal can leach from lead pipes and plumbing fixtures, especially when the water flowing through them is corrosive.
It can cause neurological and behavioral problems in children and adverse health effects in adults.
“It’s a more common problem in cities with older water systems,” NRDC Health team scientist Kristi Pullen Fedinick says, “but what a lot of people don’t realize is that even relatively new brass fixtures and faucets can still contain significant amounts of lead. Just because your home is less than 20 years old doesn’t necessarily mean you’re lead-free.”
The source of this contaminant is industrial discharge, Copper salts used for algae control in reservoirs
Copper plumbing materials due to corrosion
Acute copper poisoning: nausea, vomiting, diarrhea, gastrointestinal illness, abdominal and muscle pain.
Severe cases of copper poisoning have led to anemia, liver poisoning, and kidney failure
Bacteria, viruses, and parasites that cause illness can find their way into water supplies that are inadequately treated to kill germs.
Fortunately, these pathogens are much better controlled today than they once were.
After a 1993 waterborne-disease outbreak in Milwaukee sickened more than 400,000 people, Olson says, “NRDC really led the charge in changing the EPA’s rules and safeguards.” But clearly much more remains to be done.
Single-celled organisms lacking well-defined nuclear membranes and other specialized functional cell parts which reproduce by cell division or spores.
Bacteria may be free-living organisms or parasites.
Bacteria (along with fungi) are decomposers that break down the wastes and bodies of dead organisms, making their components available for reuse. Bacterial cells range from about 1 to 10 microns in length and from 0.2 to 1 micron in width.
They exist almost everywhere on earth. Some bacteria are helpful to humans, while others are harmful.
Parasitic infectious microbes, composed almost entirely of protein and nucleic acids, which can cause disease(s) in humans.
Viruses can reproduce only within living cells.
They are 0.004 to 0.1 microns in size, which is about 100 times smaller than bacteria.
So we need to purify the water without any exception. For your good health drink the pure water. You can contact us for water purifier service in chennai.
