What is bad about rain water?
Rainwater can carry bacteria, parasites, viruses, and chemicals that could make you sick, and it has been linked to disease outbreaks. The risk of getting sick from rainwater may be different depending on your location, how frequently it rains, the season, and how you collect and store the rainwater.
What is the cause of rain water?
Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.
How is rainwater polluted?
Environmental pollutants, harmful bacteria, and parasites can contaminate rainwater, and drinking it can make you sick. Boiling, filtering, and chemically treating rainwater can help make it safer for human consumption.
What problem does rainwater harvesting solve?
The elimination of runoff can reduce contamination of surface water with pesticides, sediment, metals, and fertilizers. By reducing stormwater runoff, rainwater harvesting can reduce a storm’s peak flow volume and velocity in local creeks, streams, and rivers, thereby reducing the potential for streambank erosion.
Why is Stormwater a problem?
Stormwater runoff can cause a number of environmental problems: Fast-moving stormwater runoff can erode stream banks, damaging hundreds of miles of aquatic habitat. Stormwater runoff can push excess nutrients from fertilizers, pet waste and other sources into rivers and streams.
What are the pros and cons of rain water harvesting?
Despite the fact that rainfall offers a very clean source of water, the method of harvesting may cause contamination of the water. When looking at rainwater harvesting pros and cons, this is one area that stands out. Sometimes, especially when using the rooftops to collect the rainwater, water may come into contact with some contaminated materials.
Are there any misconceptions about rain water?
There are so many misconceptions in the world – and rainwater is no exception. When people think of rainwater, they often think of wastewater, pollutants and even balding! Do you think these ideas are accurate?
Why is it bad to collect rainwater on your roof?
Sometimes, especially when using the rooftops to collect the rainwater, water may come into contact with some contaminated materials. For example, some roofs may contain some chemicals which can cause harmful effects if ingested or used to cater to plants. Storage limitations occur when you cannot collect and store as much water as you would like.
What happens to the water when it rains?
And now when it rains, the water (often called runoff or stormwater) runs off roofs and driveways into the street. Runoff picks up fertilizer, oil, pesticides, dirt, bacteria and other pollutants as it makes its way through storm drains and ditches – untreated – to our streams, rivers, lakes and the ocean.
