Dealing with America’s Largest Source of Water Pollution
Tuesday, March 9th, 2010Despite all the images we see in the media about big factory drain pipes dumping toxins in our waterways, America’s largest source of water pollution actually comes from activity that takes place far removed from our beaches and marinas.
Nonpoint Source Pollution remains the number one contributor to declining water quality across the country.
NPS pollution happens as rainfall, snowmelt, or irrigation water travels across fields, forests, backyards, parking lots, and other land formations on its way to the sea. Along the way, water molecules grab hold of all sorts of pollutants that are lying on the land, sweeping them up and providing a free ride into the closest stream, lake, river, or bay.
NPS pollution is such a big problem because so much of modern activity relies on the use of man made compounds. So much of what we do these days, from fertilizing our crops, to fueling our cars, painting a house, etc… releases these synthetic compounds into the environment.
Look at the puddles you see in any urban environment the next time it rains and chances are you will see a miniature oil slick or something similar. Seen individually these don’t look like much. Taken collectively, however they represent an enormous problem.
The most common NPS pollutants are nutrients and sediments that are stirred up by agricultural activity, construction sites and other earth moving events. Pesticides, pathogens, oil, salt, chemicals, and heavy metals that come from industrial as well as residential areas also contribute significantly to the problem.
The end result of our national carelessness is that today roughly 40% of America’s recreational waterways are not considered safe enough to swim or fish in anymore.
To fix this problem every citizen needs to think like a raindrop.
If it is possible for rain to mix with toxic compounds more NPS pollution will be created.
If on the other hand, we don’t let this simple bonding occur we can solve the problem.
Don’t top off your gas tank, use tarps when you paint outside to keep coatings from finding their way into the soil, wash your car house, windows, etc… with natural cleansers, be cautious cutting pressure treated lumber, dispose of batteries properly, watch what you take to the dump, and so on and so on.
Simple things to be sure, but easily accomplished with a second or two of forethought and a bit of common sense.
