Non Point-Source water pollu­tion



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?

    This is fantastic! I’m fighting my HOA board to stop the absolutely sense­less spraying of pesti­cides. We are only 2 12 miles from the ocean, and they just don’t get that these chemi­cals will run off into the storm drains and into the ocean and cause harm to the ocean. They are also causing harm to us human residents and the whole biome in the soil.
