wastewater is a gray, turbid liquid sometimes said to have an
odor of kerosene or freshly-turned earth. Wastewater contains
fecal material, urine, some food scraps and cleaning agents; basically
anything we put down the drain! But wastewater is mostly water,
containing only about 500 parts of waste in every million parts
of wastewater. That would like trying to find one of your classmates
in a sold-out Michigan Stadium.
if it's mostly water, what's the problem? The pollutants in wastewater
can cause water quality problems even in very small quantities.
Here's what we're worried about and why.
suspended particles that make the water turbid
such as phosphorus that can cause nuisance plant growth
matter: that can rob the oxygen resources of streams
metals and synthetic organic chemicals harmful to humans and wildlife
it snot a pretty picture!
