clean water act

(1972) a law that works to correct toxic effluents from industries through establishing safety standards, clean up guidelines, and penalties

safe drinking act (1974)

a law that works to provide standards for what is safe water to drink

coagulation

chemicals that act like magnets and get particles like sediment and dirt to stick together

what are the ways to be a good steward?

conservation of resources, clean up polluted areas, establishment of nature preserves and wildlife areas

what did the safe drinking water act of 1974 protect?

drinkable/potable water

pros and cons of percolation

effective but time consuming

filtration

extracts small particles

where does the safe drinking water act protect water?

in the United States

how does advancing technology improve water quality standards?

it can help filter the water and the stuff we can't see (better cleaning process)

what two things can happen to water after it hits the ground?

it can run off land or move to soil

what is bioretention? how does it work?

it filters polluted storm water from plants

explain how environmental stressors such as urban and/or agricultural runoff, industrial inputs and over-fishing can impact aquatic populations?

it will decrease the population

benefits of corporate stewardship?

no, the water is starting to get worse again

what is the leading source of water pollution?

non point sources

how effective is water treatment?

not fully protective

flocculation (floc)

particles that stick together due to coagulation

water is filtered through

percolation

what are some ways to decrease non point source pollution?

pick up after your pet, use organic fertilizer, compost, wash your car on grass, properly dispose of oil, do not put anything in storm drains

what kind of pollution does the clean water act of 1972 mostly correct?

so the water will be safe and potable

why is soil percolation important to know and understand when you are developing an area?

so you can know about flooding

point source pollution

source of pollution is known and identifiable

non point source pollution

source of pollution is too widespread to identify or blame

what influences the way water flows through soil?

texture, pore size, size of sand particles

clarification

the separation of water and floc

how do chemicals, hazardous wastes, oils, etc contribute to pollution and water quality ?

they will eventually flow to our bodies of water and can harm organisms

what was the goal of organizations like the Tennessee Water Keepers?

to enforce laws like the clean water act

stewardship

to protect the environment

what was the goal of the 1972 clean water act?

to reduce pollutants from companies

real life examples of point source pollution

toxic effluents from a factory, agricultural runoff

real life examples of non point source pollution

urban runoff from roads and parking lots, neighborhood runoff from storm drains and sewage leaks such as pig waste or pesticides, and over fishing from fisheries

what are some things that are polluting our water?

urban runoff, agriculture

water is recycled through the...

watercycle

what are some ways non point source pollution can be controlled? how do they work?

wetlands remove sediments from water

water treatment plants

where they filter, remove, and chemically sanitize water to provide drinkable water
