When rainwater is used as a supplemental household water source, homeowners and businesses should ensure that rainwater cannot enter pipes i. In such cases, to lower the risk of getting sick, if possible, avoid using rainwater for drinking, cooking, brushing your teeth, or rinsing or watering plants that are intended to be eaten. Rainwater, if appropriately harvested, can provide an alternative and potentially sustainable source of freshwater for a wide variety of domestic uses.
It can also be used as drinking water if strict safety measures are in place and carefully maintained. On that note, filtering, boiling, or disinfecting or a combination rainwater can make rainwater safe for human consumption. If you have any doubts in your ability to ensure the above, we recommend limiting your use of collected rainwater to things like gardening, washing clothes, or bathing and try to keep it out of your eyes, nose, and mouth.
Most Americans, myself included, are content to rely on and trust in the safety, reliability, and cost-effectiveness of drinking water provided by our local community water system.

In a nutshell… Many Americans collect, store, and use harvest rainwater for watering plants, cleaning, bathing, and sometimes drinking. This article addresses some of the many household uses of harvested rainwater, including how to consume collected rainwater safely.
International Rainwater Harvesting Rainwater harvesting continues to grow in use around the world where water scarcity is a daily fact of life that is only predicted to worsen in coming decades as populations increase and concentrate in arid regions. While many people in the world use rainwater as their main water supply, the water picks up bacteria, pollution, mold, pollen, and other contaminants.
You can treat rainwater to make it drinkable by using water purification tablets or boiling it. You can also use a water filtration system if you prefer to drink water from rain to conserve resources. Rainwater tanks contain many contaminants including microorganisms, bacterias, and traces of toxic metals. The story of acid rain will be explained in the next chapter.
It is hard to express in numerical values, but Adult ignorance-of-water rate is quite high. However, the problem of lack of knowledge about water is not limited to our country because water management has been processed only by experts in several countries.
These days, however, comprehensive water management as an alternative to overcome this matter is raised. This trend is to spread and enlighten the water issue to local residents as well as experts. This is clearly a paradigm change.
I hope this promise is kept in our country. In short, we should understand water properly from environment, development, industry, and education policies, and lead participation of local residents. Now you are a water agent. When it rains, I open a window and drink rainwater from my hands. Are you wondering how I could do so? As I said earlier, rainwater is the most pure distilled water in the world.
However, when I look out of the window, there are people running here and there to avoid the pouring rain. People who are running the best among them do not have much hair.
Many people would also agree with these people. Everyone thinks that the rain is a pollutant that we should deal with as soon as possible. If I tell them that I usually make tea with rainwater, they will frown at me. To be honest, it is true that rainwater is acid. The acidity of clean water is 5. If the region it rains on has the source of the air pollution, the acidity would be stronger so the level of pH will be pH The acidity is stronger as the value of pH gets lower.
However, after another 20 minutes of rain, the acidity becomes far weaker than before. Some impatient people will tell me again that it is true that rainwater is acid. However, they will change their thoughts after they hear about how less dangerous the acidity of rainwater is compared to other things. The acidity of liquids we encounter everyday is far higher than rainwater. The acidity of Cola, a typical carbonated drink, is 2.
Then, you might argue that the acidity difference between these items and rainwater is just pH. In this point, however, although the numerical difference is small, the acidity difference is in fact huge. No parents worry about the acidity in the juice and yogurt their kids drink every day. Then why are we afraid of rain, whose acidity is far weaker than that of beverage? The answer is our lack of knowledge. Rainwater Research Center in Seoul National University investigated how much the acidity of rainwater is dangerous.
We measured the pH of rainwater from a gutter of the roof. Then, during the short period of time while rainwater passes through the roof, its pH changed into This figure is not related to our health and thus rainwater is safer than juice, yogurt, a shampoo and a conditioner.
An experiment has shown that washing hair with rainwater is good for our hair and there is no problem with the acidity of rainwater.
After days, we measured the pH of rainwater again, and it was already neutralized! We can save water costs by cleaning a room and watering the flowers with this gathered water.
If you are still concerned about this, boiling the water is another way. It has rained everywhere from the past, but why do especially Koreans have an aversion to acid rain, which was not a problem in the past and in other countries? When I went to Tokyo to attend the International Rainwater Forum, Japanese housewives were treating guests with tea made up of rainwater. Someone introduced a device that operates a portable water purifier using a hand pump or a pedal so that they can filter out rainwater without electricity in emergency.
In this way, many countries including Japan use rainwater universally in everyday life. Among them, Germany, who is one of the developed countries, uses rainwater in many fields in their daily life. I hope you do not consider acid rain seriously anymore. If there is a problem, we can deal with it wisely.
So rainwater is not a disaster, but a gift and a blessing from the sky. If there is someone who thinks they became bald because of acid rain, how about raising funds that offer medical expenses and compensation? But if they want to be covered by this fund, they should prove an obvious and scientific causal relationship between baldhead and acid rain.
Now you do not need to run in the rain. I will give you a wig as a gift that is completely strong enough for acid rain. If the queen from the Snow White story were born these days, she would also have doubts about water. For this woman who has so many worries about safety, which water will be the best?
Expensive bottled water from abroad? Or, water from a mountain valley? Or, natural aquifer under the ground advertised in a beer commercial on TV?
Among them, if the safest water is proved scientifically, the queen will try to get it at any cost. However, what is the possible way of getting water for ordinary people? Approved public water could be acidic, neutral, or basic, depending on the source of the water. To put the pH into perspective, coffee made with neutral water has a pH around 5. Orange juice has a pH closer to 4. The truly acidic rain that you would avoid drinking might fall around an active volcano.
Otherwise, acid rain isn't a serious consideration. Reddy, Avanija, et al. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content.
