Rainwater Contents You Need To Know – Not a few people use rainwater for a variety of needs, including for consumption. However, not all rainwater is safe to drink.
Rainwater has a difference with other types of water. Physically, you may think that rainwater is the same as other water. But if further examined about its content, rainwater has some differences.
Here are some substances or chemicals contained in rainwater:
Rainwater Contents You Need To Know
Rainwater Contents #1: H2O or Water vapor
One of the main contents of rainwater is H2O or water vapor. The percentage is 99.9 percent and the rest depends on the layers of the atmosphere through which it passes.
This water vapor comes from the cycle of the rain, how rain occurs from the first until it comes down to the earth and even becomes rain again. From the rain process, there is such a thing as evaporation from water sources on planet Earth.
From this process it containing water vapor and forms small clouds. From that little cloud, it then clumped into a large cloud. This water vapor is safe as far as the steam comes from water sources on the earth’s surface that are safe for mankind as well.
Rainwater Contents #2: Nitric acid
The chemical contained in rainwater is nitric acid. Too much nitric acid content is not good and it can be harmful. The acid content can also be stated in pH. Normal rainwater has a pH of 6, while acid rain has a below normal pH of about 5.7 and below.
The content of nitric acid in rain can occur due to human activities due to pollution by dirty factories or from volcanic bursts.
Rainwater Contents #3: Carbon (silica and fly ash in light ash form)
Rainwater also contains carbon. Carbon substances in the rainwater in the form of silica and also fly ash. Silica and fly ash are dust substances that bind molecules to water until rain is formed. Both of these substances also play a role in the process of rain.
Rainwater Contents #4: Sulfuric Acid
Another chemical in rainwater is sulfuric acid. Sulfuric acid is a content that is present in rainwater if too much it can cause disruption to mankind breathing.
Rainwater Contents #5: Salt
The next chemical in rainwater is salt. The salt in this rainwater comes from the sea that tastes salty. Rainwater that contains many salt content is rain that happens in coastal areas. This is because the rain process due to evaporation of seawater is warmed by the sun.
The next content of rainwater is solid substances such as dust or solids that are easily soluble and gaseous. However, not all rainwaters have the same content.
The rainwater content relies on geological conditions, population, human activities in the area.
So in the mountainous area the water content will be different from the rain that occurs in the sea area. In the sea area the salt content is likely very much, while in mountainous areas the salt content will be little or even not at all.
Although microbial concentrations are generally found to be higher in the first flow of rainwater, contamination levels decrease as the rain continues. However, keep in mind, as long as it is clean.
A study from WHO showed rainwater also has mineral content, such as calcium and magnesium but the amount is small. In most cases, the chemical concentration in rainwater is within acceptable limits. However, elevated levels of zinc and lead have been sometimes found.
