Question - Why can't I drink rain water?
Joe,

Normally you could drink rainwater without becoming ill.
However, rainwater contains pollutants, soil, plant parts,
insect parts, bacteria, algae, and sometimes radioactive
materials that the rain/snow has washed out of the air.
If filtered with one of the filtering systems that you
can buy in stores nowadays, and then boiled, you could
probably drink the water safely. However, it is safer yet
to get your water from municipal water supplies or from wells
that are frequently tested.

Since ancient times, the only sources of natural water that are recognized
as safe to drink are rain water and water from deep wells. The trick is
that the rain water must be carefully handled so that it does not become
contaminated. If it runs along the ground, it's anybody's guess what sort
of microbes and toxic elements it will pick up. But if you put a clean bowl
out in the rain to collect the rain water, there's no reason you can't drink
the water from it.

Hi Joe,

The only reason I could think of where you can't drink rain water is if you
have no mouth.

OK, enough joking. In some third world nations, they drain rooftop rain
gutters into barrels to collect water for drinking. Rain water might be a
little bit acid compared to water out of the ground or from rivers, which
are somewhat neutralized from contact with minerals, so you'd be missing
some of those minerals.

If you live in a really polluted city, it might be a good idea not to drink
rain when it just starts, as it's washing out all the particulate material
in the air (car exhaust, diesel fumes, dust, etc). Other than that, I
can't think of why you shouldn't be drinking it.

There is no essential reason why you can't drink rain water. I think the
concern about drinking rain water has to do with the fact that in our
non-pristine environment the raindrops may have picked up some contaminant
on the way down from the clouds.

Dear Joe-

Most likely, you ARE drinking rain water..! The water that comes from the
tap in your home at some point in the past fell as rain water (or snow). It
may have flowed into the ground to become part of the groundwater supply, or
may have arrived in resevoirs via rivers and streams. Usually this water is
treated to remove impurities and harmful organisms.

But you can collect rainfall and drink it also. It should be collected and
handled under sterile conditions, however. Much of the world's water supply,
especially in the tropics, comes from rain water.

Why Save Rain Water

Why save Rain Water….

Only ¼ inch of rain is needed to fill a 60 gallon barrel. Sixty gallons can cover about 100 square feet with 1 inch of water. This can go along way in offsetting garden needs in the spring and summer months when water consumption increases anywhere between 20 and 200%. Capturing rain water in a barrel before it hits the ground decreases storm water run-off, which otherwise carries pollutants from paved surfaces into groundwater and rivers. Furthermore - you can save money by saving water - if your water is supplied by your town and you also use town sewer - more often than not the sewer usage is measured by your incoming water. In Boston for every $1.00 we pay for the water to come in, we are charged $2.00 for sewer usage - even if the water is not being flushed out. So you are still paying sewer fees on the water that you use to water your lawn, garden, fill your pool and wash your car! SAVE RAINWATER and SAVE MONEY!
