Advantages:

1.Water purification can protect against harmful organisms

Studies have shown that unfiltered water may comprise microorganisms causing diarrhoea, vomiting and even death. Water filtration systems are required to clean the water and kill these microorganisms in order to provide people with safe drinking water. Without water purification or some sort of treatment, 90 percent of the world’s water supply is unfit for drinking.

2.Water purification removes toxic metals

Apart from the microorganisms that untreated water contains, it is also seen as a source of various minerals, including copper and magnesium. Even though some of these minerals do not necessarily pose a threat to one’s health or life, they may react and respond to different minerals, like lead and copper, which are harmful to the human body. A variety of treatments, such as disinfectant agents, chemicals and filtration systems, are employed to help decrease risk and illness by removing as much as possible of the minerals from the water.

Disadvantages

2.Water purification may not remove pesticides

Pesticides are often used on farms or garden and run the risk of discharging into water supplies. In the event that there is a well that is contaminated, it has to be tested for pesticide pollution, as only municipal water can be treated. In dealing with pesticides and using home water filtration systems, it may not always prove to be as effective. These systems can help with the removal of chlorine and other weighty and intense metals like mercury. It may however, not be able to remove pesticides. Of a bigger concern is long-term exposure to these pesticides in water which increases increase the danger of getting serious diseases such as cancer.

2.Water purification require regular maintenance

Water purification systems that are home-made are not always effective in providing safe drinking water. These systems have to undergo regular maintenance and often have to be replaced in order to effectively filter out all the dangerous organisms and metals. Non-adherence to these prescriptions will cause one a lot more harm than drinking directly from a tap.

Water purification is an admirable concept, but should be implemented with utmost care. Water and filters should be maintained regularly, efficiently and effectively in order to secure safe drinking water. Water should be clear of microorganisms and toxic metals which can cause life threatening diseases. The water should be life-enhancing, and not life-threatening.
