Non-point-source pollution. illustration by Paul Mirocha
Non-point-source pollution. It comes from everywhere and flows downhill, concentrating in the water.

 

Your feet pound the pavement as you dash through the rain. You glance down and notice pieces of trash flowing beside the road. Where does all that trash come from?

Experts call this nonpoint source pollution (NPS) because it comes from many diffuse sources. Types of NPS include dirt, nutrients, bacteria, chemicals, oil, and trash. These pollutants flow unfiltered into our waterways. NPS threatens water quality across Texas.

NPS makes people sick and harms ecosystems like Spring Lake. Take a moment to look at Spring Lake. Is it worth protecting?

  • Hey Paul,
    I am working with Staff at the Meadows Center @ Texas State and they have forwarded your illustrations to me for consideration in publication about water resources. I was wondering if we could speak at your convenience about this opportunity.
