What is watershed?

• water that flows over land and has not absorbed into the ground

• all of the land area that supplies water to a particular area

• withdrawing groundwater for people to drink

• a type of pollution that comes from a distinct place like a factory

Cannot easily be traced to the source of the pollution.

• Point Source Pollution

• Non-point source pollution

Can be traced back to the point of origin.

• Point Source Pollution

• Non-point source pollution

Organize these options into the right categories

Groups:

(a) Nutrient Pollution

,

(b) Ocean Water Pollution

,

(c) Toxic Chemical Pollution

,

(d) Biological Pollution

• bodies of water with high nutrient content & low oxygen content

• can pollute surface water and/or groundwater

• eutrophication happens here: buildup of phosphorus & nitrogen

• more human health problems are to due this type of pollution than any other type

• nitrogen is the most damaging

• pathogens make their way into air, soil, & water

• pesticides, detergents, and oil are being dumped

• red tide happens here: algal blooms produce reddish pigments

What are some solutions to reduce water pollution?

• using a low-flow toilet

• fixing leaky pipes

• turning off the sink when you're brushing your teeth

• recycling and throwing things away correctly. Not just dumping it down the drain
