The Weight of Fresh Water

May 29th, 2009 by Linda Jenkinson

Water is a pretty weighty commodity. A gallon of the stuff weights 8.3 pounds, yet, the real weight of water is in how necessary it is to life. We drink it, cook in it, and bathe in it. Our plants need it to grow. According to the U.S. Geological Survey (USGS),

“Up to 60 percent of the human body is water, the brain is composed of 70 percent water, and the lungs are nearly 90 percent water. About 83 percent of our blood is water, which helps digest our food, transport waste, and control body temperature. Each day humans must replace 2.4 litres of water, some through drinking and the rest taken by the body from the foods eaten.”

We have an R/O water system (reverse osmosis) in our home because the chemicals our city needs to provide clean water leave a nasty taste behind. The system is a water tank with special R/O filters that intakes the city water, cleans it, and dispenses it from a drinking water tap in our kitchen sink. The entire system cost less than $100.00 and it’s well worth the price.

A while back, in Piles of Poo, I talked a little bit about how pet waste can pollute ground water. It just figures that doggy-doo is a pollutant. Today I watched a video from a Kentucky 4th grader that reminded me that other, everyday forms of waste can pollute water, too. I hope you enjoy it as much as I did.

I was struck by Sara’s footage of an illegal dump site.

I don’t know how many times I’ve seen an illegal dump site as I walked through the woods or passed by one while driving. All of the nasty crud in this waste seeps into the ground water, the stuff of life. It would be a very small step to report it to the Department of Natural Resources (DNR) or to find a group willing to clean it up.

These days, many states offer free advertising on road signs to groups that “adopt a highway”, Each group signs up to clean up a mile or more of trash along their adopted stretch of road. Their small steps help us all to not only preserve the purity of the ground water, but also to restore their part of the world to its natural beauty.
