Find out the dangers of contaminated water and know more about water purification tips from the water contaminated by flood and storms through the following article.

Contaminated water - a terrifying potential risk after the storm

Water sources after every storm mostly fall into extremely serious pollution by rubbish, feces, animal carcasses . according to flooding water flowing into wells and common water tanks.

In the composition of water tanks contaminated with lakes, ponds, rivers and streams . we can find real assassins like Naegleria fowleri - also known as brain feeding amoeba , Anabaena cyanobacteria specialized in producing Neurotoxicity causes respiratory arrest.

Besides E.coli in animal manure and Salmonella in polluted water, they cause many intestinal and digestive diseases such as typhoid, diarrhea .

Many pathogenic bacteria exist in contaminated water

That is not to mention the chemicals, heavy metals, pesticides from the soil also mix water. The most dangerous is probably arsenic (arsenic) - a colorless, odorless, tasteless substance in water but fatal if only one amount of corn grain is used. So how do we remove toxic substances from contaminated water?

Tips for cleaning clean water from dirty water

There are many ways and means to do this. However, the following three temporary methods can be used, not only simple but also extremely economical.

First, boiling water is the most effective way to kill bacteria. For water sources suspected of being infected with bacteria, temperature will be the best weapon.

Note that, let the boil water boil for a period of 5 minutes, when the temperature will destroy more bacteria in the water

According to experts, heating water for 15-20 minutes helps you get 99.9% clean water. This method can be used both in everyday life and when you are in distress in nature, such as getting lost in a forest. However, the disadvantage of boiling water is that it cannot remove heavy metals and toxic minerals because they do not evaporate if mixed in water.

You can use clean towels, medical cotton or filter cloth to remove residue and toxic minerals after the water is finished.

The second method is recommended, which is to use water purification tablets or water-cleaning chemicals. Can be mentioned as chlorine, iodine, potassium permanganate . are chemical substances capable of antiseptic, kill bacteria very well. Just put a few drops of iodine in the contaminated water, wait about 20 minutes to use it immediately.

This method is economical and convenient to use. You can completely bring iodine tablets with you, just in case. However, this also has some weaknesses, that is, iodine's taste is usually quite strong and the treated water will be slightly dark.

On a larger scale, after the rainy season, the water sources such as drilled wells, water tanks are swept by floodwaters of animal corpses, feces, and garbage. To solve this problem, alum can be used - an easy-to-find and familiar ingredient.

Specifically, dirty water will be cleaned with alum (20g for 1m ^{3 of} water) and a bed of sand will act as an initial water filter. After that, the finished product is passed through the filter model to make the water clearer. Finally, the water is passed through the charcoal layer to deodorize and we get clean, standard products of the Ministry of Health for living.

Use surroundings to make water purifiers

In addition, the third method recommended for emergencies is to use surrounding objects to make a water purifier . Just cloth buckets, tampons, or natural filters like birch bark have a funnel in place. Of course, this filter only helps clean water from small soils and sand, but does not kill all bacteria in the water.

Remember, these 3 tips are just a temporary method to help your body not be dehydrated. After flood and storm, you need to quickly find ways to access clean water sources to protect your own health.

* Lack of water and harm to people

Contamination of common water supplies after natural disasters not only causes disease but also inevitably leads to water shortages. And if you don't solve the problem soon, people will face horrifying perspectives.

90% of the lungs, 80% of the brain and 85% of human blood are water.Simply put, without water there will be no life anywhere

We know that 2/3 of the body is water. People who can fast for 3 weeks but do not have 3 days of drinking water are difficult to live. Every day, adults need to charge about 2.5 liters of water to survive. Therefore, when the surrounding water sources are contaminated and cannot be used, the consequences will be unpredictable.

According to scientists, the first signs of not having drinking water are feeling of thirst, dry mouth. More heavily, you begin to feel dizzy, lightheaded and depressed. The urine of a dehydrated person will also be characterized by a very deep yellow color, along with constipation at any time.

Inside the body, the condition will become much worse. The brain begins to perform a series of instructions, drawing water from other parts of the body to maintain activity. This helps the brain continue to live, but most other organs have problems.

The blood will become denser, so the heart must use more force in the process of contracting, pumping blood through the arteries. This reaction raises blood pressure, causing life-threatening for people with a history of blood pressure and cardiovascular disease.

On the other hand, without water, kidneys will work moderately and "flutter", disrupt the secretory function, long-term toxin infection, causing kidney stones and kidney stones. Finally, if people lack water for too long, people will fall into the 'superhydration' phase: seizures, rapid breathing, weak vessels, leading to heart failure and death.
