For some \"water, water, everywhere!\"It\'s a comedy story, but it\'s not fun for the rest of the world.Although water is abundant on the Earth, it is one of the most scarce commodities, in quantity and quality.Despite technological advances, drought and water-borne diseases are common worldwide.
The supply of drinking water is faced with various sources of pollution, so consumers are confused about its water quality.On the one hand, we believe that drinking water is well treated and safe to drink, on the other hand, we can see news reports about some inefficient water treatment plants, or operators who try to manipulate the results of the water test.Water advice is commonWhen some pollution is found, it is recommended that consumers wash water before drinking.
One relief is that the EPA noted in the \"tap water\" report that \"there are very few actual incidents of drinking water pollution, and usually they do not occur at levels that may cause health problems.But the report also said, \"more and more activities will pollute our drinking water .\"\"The supply of drinking water (surface and groundwater) may be exposed to contaminants from sewer spills, sanitary spills, rain drain, centralized animal feeding operations, failure of septic tank emissions, and many others.
These contaminants include fertilizers, pesticides, medicines, toxic waste, oil, radionuclides and metals.Drinking water supply is sometimes exposed to harmful pollutants from the source.Disease-Causes bacteria to enter the city\'s drinking water, tap water, or contaminated ice.
According to the 2002 CDC report, from 1985 to 2000, 251 outbreaks related to contaminated drinking water and 462,169 water-borne diseases were reported.Some of these cases relate to the source of surface water supply contaminated with sewage.Some drinking water pollution is related to sanitary sewer overflow (SSO) and raw sewage discharged to the water supply line.
Water 42%The outbreak of diseases related to the bug.EPA identified 59 CSO exports in seven states, less than a mile from drinking water intake.While the report to Congress did not find any relationship between the CSO emissions of these exports and the transfer of pollutants to the vicinity of the drinking water inlet, it said that more complex modeling is needed in order to do better research.
Lead in the home plumbing system can pollute the water.Lead contamination can lead to various health problems.According to EPA, \"in infants and children, the level of action for lead in contact with drinking water is higher than 0.
015 mg/L can lead to a delay in physical and mental development.\"While lead rarely pollutes the water in the water supply system, lead penetrates into drinking water from corrosion pipes with lead pipes, joints and welding at home.The good news is that advances in water treatment technology make it possible to remove these water contaminants from our drinking water.
Although technology has not caught up with pharmaceutical water pollution, most water treatment equipment can remove drugs containing volatile organic chemicals (VOCs.According to NSF International, although many NSF-certified water treatment equipment is designed specifically to remove drugs, \"Many of these products can help provide additional protection against a wide range of other contaminants.\"Consumers have a variety of water treatment equipment to choose from and you don\'t have to buy bottled water --To get healthy water, it can cost you a lot of money every year.
In fact, studies have shown that some bottled water contains a certain amount of bacteria.This is because tap water and bottled water are not regulated by the same standards and by the same agency.A study by NRDC showed that 103 of bottled water in 1 brand of bottled water per 3 had a certain level of contamination, including traces of arsenic and E.
(NRDC, 999).
In addition, the household filtration system can improve the taste or appearance of tap water at a minimum cost.According to an article in the FDA consumer magazine, \"water purified with these products is usually cheaper than buying bottled water.According to Brita, it\'s highThe end faucet filtration system provides 18 cents per gallon of water, saving a lot of money from usually 8 cents or moreto 12-An ounce of water.
Experts suggest that you should find out the type of contaminants in your water before you decide which water treatment equipment to purchase.The price of the home water test kit is between $9.If you want to test multiple parameters, 00 to about $99 or more for a single parameter.
The bottom line is that it\'s cheaper to test your water because you don\'t want to buy or be forced to buy some sort of water filter just because the salesperson says it\'s good.A typical water filter is designed to treat one or more contaminants.Most water treatment equipment is certified by the National Health Foundation (NSF) International.
The NSF (not to be confused with the National Science Foundation) is an independent third party organization that has tested and certified thousands of water treatment equipment such as household filters, softener, and purifiers to confirm treatment requirements.Once you have confirmed what is in your water and studied two or three water filters, you should confirm the statement of treatment of these water filter manufacturers, and then, choose the best water filter or purifier.If the treatment device you found is not certified, please call the manufacturer for the reason.
Please note that the treatment equipment may be tested but not necessarily certified by the NSF.What choice do you have?Again, the selection of the filter device will depend on what the test confirms.For most people, using a water filter may not be a problem, but it may be necessary for those with impaired immune systems.
There are different choices in business.
You can buy a point.
of-If you want to process all the water that comes to your home, enter the (POE) water treatment unit.Install POE or full house water filter on the water pipe entering the house, which requires an experienced plumber to install.A point-of-Use (POU) equipment is installed where water is allocated around the house.
These types of equipment have water filters under the sink or under the counter, countertop, glass bottle, shower head and refrigerator.POE (Full House filter) can install activated carbon and reverse osmosis filters in this order.Some are multiple.Stage unit with multiple series of activated carbon filters to protect the reverse osmosis filter.
Multi-APEC Pure ($629) ($385-$469), Aquasana ($799) is the NSF-certified.The water softener is ideal for families to use hard water.You may want to consult your local government that the softener is allowed due to an increase in the chlorine content emitted by the softener.
Most wastewater treatment facilities are not designed to remove excessive chlorine, resulting in excessive violations of their licenses.As a result, some local governments have banned the use of soft water machines.Prices vary for all types of water softener.
For POU water treatment equipment, countertops or table top water filters of various shapes and models are available.The desktop water filter is the ideal choice for homeowners who do not want to tamper with pipes and tenants who do not allow him/her to modify the pipe system.Some plumbing work is required for water filters.
This is ideal for water treatment in one location of the house.The price will depend on the model and type of filter in the device.In summary, please check the CCR report or test the water before selecting the appropriate water treatment equipment.
Considering the long-term cost and health benefits, the most important thing is to read fine print.Research NSF-Certified water treatment equipment.References: 1.camping-water-purfier.com/water-filters.2.2004.3.5.6.Committee on the conservation of natural resources.
