What is the role of storm drains in watershed pollution?

Back

Storm drains collect runoff from streets and direct it into water bodies without treatment, potentially carrying pollutants.

Front

How can animal waste affect water quality?

Animal waste can introduce harmful bacteria and nutrients into water bodies, leading to pollution.

Front

What is the significance of groundwater?

Back

Groundwater is a vital source of drinking water and can be contaminated by pollutants from the surface.

Front

What are septic tanks?

Back
