Can you drink rain water after you boil it?

Rainwater is generally safe for most people, however, it can sometimes be microbiologically compromised and have a lower microbial quality than mains water. This is particularly common after rain, where E. Boiling, Filtering and Chemically Treating Rainwater Can Help Make It Safer for Human Consumption. However, it is important to have reliable collection, treatment and testing systems before drinking it.

Boiling has been shown to kill some of the disease-causing organisms likely to be in rainwater tanks, but certainly not all. Before using collected rainwater for drinking, bathing, or cooking, consider whether treatment is needed to make it safe. Testing water can determine if it contains harmful germs, chemicals, or toxins. Water treatment options include filtration, chemical disinfection, or boiling.

Filtration can eliminate some germs and chemicals. Treating water with chlorine or iodine kills some germs, but doesn't remove chemicals or toxins. Boiling water will kill germs but won't eliminate chemicals. Using a simple device called a “first flush diverter” to remove the first water that enters the system can help avoid some of these contaminants.

The amount of water to be removed with a first flush diverter depends on the size of the roof being fed to the collection system. If you collect and store rainwater for drinking, you have an individual water system and are responsible for ensuring that the water is safe. We talked about the challenges with rainwater tanks, the dangers lurking inside the tank, and everything you can do about them. To ensure that the water you drink is truly safe, it's important that you get your water from a bottled water company that knows how to properly purify it.

The best course of action is to install a rainwater tank filter that treats all of the water that will flow into your home. However, it's important to note that while rainwater is the cleanest form of water on the planet, it still needs to be properly filtered to ensure that the person receives the healthiest and cleanest water possible. Both the time it takes to heat the water and the temperature to which it is heated affect the resulting purity of the water. It's important to treat the water in your rainwater tank before drinking it, because roof water is contaminated with up to 18 different contaminants, including bacteria, viruses, mold, and harmful chemicals.

We created a useful resource for those who are still learning how to understand the water coming out of the rainwater tank. If you want to use the water for domestic purposes and not for drinking purposes, you can also ensure that your water undergoes a filtration process to remove any heavy metals it contains using a domestic water filtration system. We always recommend a second line of defense, a tabletop or under-sink water filter, which will trap any contaminants that are a threat between the water tank and the kitchen sink. Water filters remove dirt, bacteria, heavy metals, pesticides, chlorine, and other harmful contaminants from drinking water, which doesn't work when boiling.

We'll tell you what the best pH levels are for your drinking water and how you can tell if your water isn't safe. Although not necessary, cooling rainwater delays the growth of most of the microorganisms it might contain. Don't drink rainwater that has escaped from plants or buildings because it could pick up toxic and pathogenic chemicals from these surfaces. Much tap water comes from soil and more than 50% of bottled water sold in the United States comes from groundwater.
