WEEK 5 FEBRUARY 18, 2015

Today Review from last time – stream bioassessments Industrial activities in the watershed Fun activity – make your own water filter

Review from last week Questions

Filtration of stormwater though soil

Filtration Pollutants are removed from stormwater as it flows through soil, due to physical and biological processes: Physical processes: – Deposition or attachment of particles – Adsorption of pollutants Chemical processes: oxidation / reduction Biological processes: microorganisms Chemical and biological processes (but this takes time)

MAKE YOUR OWN FILTER
