Name for water found in rivers, lakes, and streams.
Surface water
What are the 5 Great Lakes?
Huron Ontario Michigan Erie Superior
Rainwater that flows over land and carries pollutants into waterways is called this.
Runoff
What does MCL stand for?
Maximum Contaminant Level
Substances besides water molecules that are in water (usually negatively affect water safety).
Contaminant
This lake is the only Great Lake located entirely within the United States.
Lake Michigan
Why do scientists and engineers monitor water quality in rivers, lakes, and groundwater?
To protect our water & community.
What does MCLG stand for?
Maximum Contaminant Level Goal
Water that has been contaminated by human use. For example, water flushed down the sewers.
Wastewater
Which of the 5 Great lakes is the largest?
Lake Superior
What are two actions communities can take to protect their drinking water sources?
Make communities aware of storm drains using posters, host collection days for waste, etc.
Why would it be necessary to test different water sites within the same city?
- different contaminants
- different amounts of contaminants
- to ensure the testing kit isn't faulty
(Typically) treated wastewater that is sent back out into the environment, usually to a surface water body like a lake.
Wastewater Discharge
How can fertilizers or pesticides used in agriculture affect drinking water supplies?
Contaminants may enter our drinking water through runoff and groundwater.
Explain why storm drains can sometimes carry pollution into rivers or lakes.
Storm drains found on streets and sidewalks lead directly to our lakes, rivers, and creeks without being filtered. So when water from the road enters the drain it carries any contaminates like gas and oil with it.
Why is the EPA important?
They are responsible for protecting the environment including our water supply
A process such as filtering that improves water quality and allows it to be used for a certain activity, such as drinking.
