Rainwater from your rain water tank or rain barrel can be made safe by appropriate filtration/purification measures. Filter systems are available that will ensure your rainwater is one of the healthiest sources of drinking water, with a few caveats (see article below). It is also important to ensure your water tank is made from food-grade materials and is safe for storing potable water.
I am a big fan of harvesting rain water for household purposes, such as showering, bathing, laundering, watering lawns and gardens, and so forth.
There is no question that harvesting rain water is an effective way to conserve water and save money. But it is healthy to drink?
“Since ancient times, the only sources of natural water that are recognized as safe to drink are rain water and water from deep wells,” writes Richard E. Barrans, Jr., Ph.D., Assistant Director of the PG Research Foundation.
“The trick is that the rain water must be carefully handled so that it does not become contaminated.”
The purpose of this article is to consider some of the potential health advantages and disadvantages of drinking rain water on a regular basis.
In addition, rain water does NOT contain the levels of chemicals (such as chlorine and fluoride) that are used in municipal water treatment facilities.
Numerous health conditions are related to the ingestion of both chlorine and fluoride.
Another obvious advantage of drinking rain water is that it is inexpensive.
However, availability is also dependent on the climate for harvesting. It should also be collected and handled only under sterile conditions.
One of the most important factors regarding the quality of rain water has to do with the environment in which it is collected. Rain water harvested in a pristine environment, such as high in the mountainous, unpopulated regions of the world, is going to be of much cleaner than rain water collected in a polluted big city.
According to David Cook of the Argonne National Laboratory, “Rainwater contains pollutants, soil, plant parts, insect parts, bacteria, algae, and sometimes radioactive materials that the rain or snow has washed out of the air.”
“Air-borne pollutants from hundreds of miles away can spread quite rapidly. Because of this fact, it would most likely be necessary to test the water on a daily basis to ensure safe drinking.”
Cook says that if “harvested rain water is filtered with one of the water filtering systems that can be purchased today, and then the water is boiled, we could probably drink the water safely.”
However, he says, “It is safer to get your water from municipal water supplies or from wells that are frequently tested.”
In addition to the problem of contamination, rain water is slightly acidic compared to water out of the ground or from rivers.
Ground water comes into contact with natural occurring minerals, many of which are necessary for optimal health. Mineral rich water is slightly alkaline in pH, which is much more supportive of health in the human body.
Rain water is similar in pH to demineralized waters like distilled and reverse osmosis.
Thus, drinking rain water that has been properly harvested and adequately filtered is an acceptable form of drinking water (in many cases better than tap water or bottled water). However, I do not believe it is as health promoting and as hydrating as mineral rich water and ionized alkaline water.
If you do drink rain water for more than a few weeks, I recommend replenishing trace minerals in the body by adding an unrefined natural sea salt, such as Celtic sea salt, to your water or food.
