Purification of water can be done by various processes like using UV filtered water purifier, reverse osmosis, etc. The potable water made available by the factories can be considered potable? Is the water really free from water pollutants?
What is the cheapest way to purify water?
The cheapest, safest, and easiest way to purify water is the boiling method of water purification. Boiling is sufficient to kill pathogenic bacteria and viruses but it cannot remove all the heavy contaminants.
Why do people store water in earthen pots?
In earlier days people used to store their water in earthen pots in order to keep the water clean and cold and also in brass vessels for healthy living. Afterward, People started using filters and now it’s the age of water purifiers. Still, there are many places in the world where people don’t have access to “potable drinking water”. In many small places, the woman in rural areas has to walk an average of 25 kilometers or more to fetch potable water. In developing countries like Africa, access to a potable water supply is still very difficult. Now the question arises what is “potability” or what potable water is?
How does water purification work?
This method is effective because water has a lower boiling point than other contaminants and disease-causing elements found in water. Water is heated until it attains its boiling point. It is then left at the boiling point until it vaporizes. This vapor is directed into a condenser to cool down. Upon cooling, the vapor is reversed into liquid water that is clean and safe for drinking. Other substances having higher boiling points are left as sediments in the container.
What is the purpose of the National Secondary Drinking Water Regulations?

Is tap water potable?
Images by Fabio / Getty Images. Potable water is water that is considered safe to drink. Tap water has usually been treated by the local municipality to make it potable, but there are times when the supply has been contaminated and you must treat water before using it.
What are non-enforceable water standards?
Non-enforceable terms include; Lifetime Health Advisory Levels, Public Health Goals, Minimum Risk Levels, and Maximum Contaminant Level Goals. All of these are non-enforceable terms, and therefore municipal water treatment facilities do not need to comply with them. The only enforceable safe drinking water standards are Maximum Contaminant Levels and Action Levels.
What does it mean to set drinking water standards?
Also, setting more stringent safe drinking water standards means that municipalities are responsible for complying with new allowable limits. This often means purchasing detection equipment as well as expensive filtration technology.
Why are Enforceable and Non-Enforceable Standards Different?
To address this, EPA creates Maximum Contaminant Level Goals (MCLGs) which refer to “the maximum level of a contaminant in drinking water at which no known or anticipated adverse effect on the health would occur..” Again, these are non-enforceable levels. In 2001, EPA set an enforceable Maximum Contaminant Level (MCL) of 10 parts per billion for Arsenic in drinking water. That same year EPA adopted an MCLG of 0 parts per billion. This was EPA’s way of acknowledging that there really is no safe level of Arsenic in drinking water. EPA is unable to adopt a lower threshold because municipal water systems across the country would be out of compliance. EPA has to balance the cost imposed onto municipality, with the benefits associated with human health. This same principle goes for unregulated contaminants with health advisories. EPA set a lifetime health advisory of 70 parts per trillion for PFOA. Soon after, the Center for Disease Control recommended reducing the advisory level to 20 parts per trillion for the same contaminant. Finally, there are several health and regulatory agencies that understand that federal limits are set way over a safe threshold. At Hydroviv, we look at toxicological data instead of regulatory data when determining if your water is safe. We prefer to make recommendations about what doctors and pediatricians say is safe.
How many contaminants are there in the EPA?
There are only 90 contaminants regulated under this act, and thousands of others that are not. Unless mandated by the state, municipalities don't account for any unregulated contaminants. According to EPA, if the levels for each regulated pollutant meet EPA’s standard, then the drinking water is in compliance and therefore "safe".
Why is the EPA unable to lower the MCLG?
EPA is unable to adopt a lower threshold because municipal water systems across the country would be out of compliance.
Why do we need water?
To stay hydrated, you need water with minerals, or a sports drink with added electrolytes to replace what’s lost through sweat. Distilled water cannot make up for what expels from the body because distillation removes electrolytes. Similarly, if you’re sick or malnourished, you need all the minerals you can get.
What are the different types of water?
Before reading this article, you may have thought all water is the same. It turns out, that’s not the case. There are specific differences between each type. Let’s take a closer look at arguably the two most common types and see how they differ: 1 Distilled Water: We’d hate to sound like a broken record, but again, distilled water is a specialized type of purified water produced by boiling water, collecting the steam, condensing the vapor, and storing it in a separate container as distilled water. During the distillation process, 99.9 percent of salts, minerals, and other organic and inorganic materials are removed from the source water. 2 Filtered Water: Filtered water usually starts as plain tap water or well water. This water passes through some combination of carbon and micron filters, which helps clear out sediments, chemicals, heavy metals, pathogens, and various other contaminants from the water. Filters can also eliminate foul odors and tastes. Tap water is usually filtered for impurities and particles and then treated by municipalities to ensure its safety.
Why is distilled water used in hospitals?
These facilities use distilled water to sterilize medical instruments and for hand-washing. The zero-mineral content of distilled water means sterile instruments won’t have any spotting or residue left on them. It also won’t leave deposits on the equipment used to sterilize them.
What happens to distilled water after it is cooled?
The cooled steam then condenses and returns to liquid form, leaving behind any mineral residue and contaminants. Finally, the resulting liquid (the distilled water) is collected in a separate, sterile storage container.
What is distilled water?
In the simplest terms, distilled water is the resulting liquid created when water is converted into steam, condensed, and returned to a liquid state. According to the University of Georgia (UGA), 99.9 percent of all impurities, natural minerals, and other dissolved and suspended substances from the source water remains behind.
How long does it take to distill water?
A typical countertop distiller takes around 4 – 6 hours to produce one gallon of distilled water. Furthermore, distilled water can be double distilled to ensure high purity.
Why do water authorities issue boil water advisories?
This is why whenever the water supplied by public water systems becomes compromised, or natural disasters damage municipal water steam , local water authorities will issue boil water advisories.
