Non Point Source Water Pollution
This illustration explaining the complex, mostly invisible, process of non-point-source water pollution was created for a series of outdoor exhibit signage fro The Meadows Center for Water and the Environment at Texas State University.
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?
