memorize

Treating Groundwater Sources

Question Answer
what is done to groundwater before it can be obtained from a well?it is filtered to remove contaminants
which is generally cleaner and requires less treatment, groundwater or above groundwater?groundwater
water from above-ground sources also need to be _______ before it becomes clean drinking watertreated
what can be done to water to kill harmful organisms (but not physical or chemical contaminants)boiling water
_________ water sources require more treatment than _______ water sourcespolluted, cleaner
water treatment is very ________expensive
memorize

The Water Treatment Plant (idk how to do this lol)

basically say the next stage?? hmmm....
Item Next
water comes into the system that filters out large solids (plastic bottles, litter, plants, fish etc)...
water is pumped into a large holding tank where a chemical is added to make small solids clump together and settle to the bottomwater is passed through a special membrane filter to take out any tiny solids
water is passed through a special membrane filter to take out any tiny solidschlorine is added to kill any microorganisms that have not been removed by filtering alone
chlorine is added to kill any microorganisms that have not been removed by filtering alonethe drinkable water is pumped out to storage sites such as water towers and underground reservoirs
the drinkable water is pumped out to storage sites such as water towers and underground reservoirslast
memorize

what does pH (roughly) meanpotential hydrogen
what does the pH scale measureacidity/alkalinity

the pH scale goes from _________-_________0-14
0 is the most ______acidic
14 is the most _______alkaline
7 is _____neutral
each whole value that goes/up in the pH scale is ___ times more acidic/alkaline10
memorize

Managing Our Water Systems

Introduction

Question Answer
most people in Canada obtain water from a ______ water supplymunicipal
________ manage the removal of waste watermunicipalities
where is waste water sent to from sinks, drains etc?a treatment plant
what happens after water is treated in a plant?the water is discharged to nearby rivers/lakes/oceans
memorize

Treating Waste Water

Question Answer
within waste water there is anything flushed down the system such as...soap residue and human waste
what would happen if we put back our waste water directly into the rivers and lakes?we would contaminate our drinking water sources
what do we do to our waste water before it is put back into the rivers?we treat our water
memorize

Septic Systems

Question Answer
a rural home gets its water from a ________ _____drinking well
a rural home probably disposes of its waste water through a _______ _________septic system
what is a septic system?a self contained wastewater treatment facility
how does a septic tank work? (long ass answer... go study a diagram)all waste from a sink or toilet enters a septic tank immediately. the bacteria in the tank begins to break down the waste. the solid material goes to the bottom, and lighter material float to the surface. the liquid layer in between flows into pipes that lead outward. the wastewater contains organic matter and nutrients such as nitrogen. the pipes leading from the septic tank are on the bottom. this means they have small holes that allow the nutrients into the soil. the bacteria digests and breaks down the organic waste and the liquid returns to the groundwater supply.

the _____ and _____ from the plants filter out contaminants just like in a natural settingroots and soil
memorize

The Wastewater Treatment Plant

Question Answer
the most expensive facility in most communities is usually...the wastewater treatment plant
if a city of 50 000 people maintained a wastewater treatment facility, how much would it cost?can cost over 40 million
treatment of wastewater involves a _______ _____ and network of ________ ____ that takes waste away from the plantphysical plant, underground pipes
memorize

Protecting Drinking Water Sources

Question Answer

memorize

Who Manages Our Water

Question Answer
all levels of _________ help manage Canada's water systemsgovernment
what do Ontario's laws to protect drinking water require communities to do?they require communities to identify how the quality of the drinking water might be threatened, and to make an action plan to reduce/remove those threats
memorize

Stewardship through Water Conservation

Canadians pay ____ for treated water than the true ____ of treating itless, cost
Canadians pay less for treated water compared to...people living in other developed countries
water use is much ______ in other parts of the world than it is in Canadalower
memorize

The Benefits of Water Conservation

Question Answer
what are the benefits of water conservation for those who have less access to water?having water when needed, not contaminating the water supply
what are the benefits of water conservation for even people who an take water for granted?ensuring water supply, saving money, putting less demand on water distribution and collection systems
memorize

Water Use

Question Answer
which industry uses the most freshwater and why?the agricultural industry, because crops require enormous amounts of water
how can agriculture pollute water systems?by leaching pesticides and fertilizers into the water supply
is water that flows through the sewage system (toilets, sinks, etc) treated?yes
is water that flows into the storm drains treated?no
demands for freshwater ________ with industrializationincrease
what is water used for in industries?solvent, coolant, transport agent
what is water used as a source of energy for in industries?water is a source of energy in the production of wood/paper products, steel, plastics and many other things
what is an inevitable by-product of industry?toxic water
how is thermal pollution caused?when water is used to cool industrial machinery is returned to a water body at a higher temperature
memorize

Changing How We Pay for Water

Oil Spills

these are from my own notes that i took. might be wrong
Question Answer
what is oil?oil is a viscous liquid derived from petroleum, generally used as a fuel or lubricant
what are the four types of oil?very light, light, medium, heavy
what is an oil spill?an oil spill is the release of oil into the environment, especially the marine ecosystem, and is a form of pollution
how can oil spills happen?an accident or human error
what is a boom?a temporary floating barrier used to contain an oil spill
what are the pros of booms?easy to use, oil can reused
what are the cons of booms?dependent on sea conditions, can be slow
what are sorbents?sponges placed on the surface of the spillage affected area that suck and absorb oil from the surface of the water
what are the pros of sorbents?can stop oil from spreading, safe to use
what are the cons of sorbentscauses secondary pollution, expensive
what are dispersants?chemicals that break the oil down into smaller groups, used to allow microorganisms to eat the oil faster
what are the pros of dispersants?easy to apply over a large area, makes the oil less toxic
what are the cons of dispersants?dispersants are toxic, hurts marine life, and is almost impossible to remove from the water
what is burning?burning the oil where the spillage occurred until there is no more oil left
what are the pros of burning?quick, easy, effective in getting rid of a lot of oil
what are the cons of burning?pollutes air with smoke, kills marine life in area because of the water being heated, dangerous
what is bioremediation?microorganisms that eat oil, generally used after dispersants are added to speed up process
what are the pros of bioremediation?eats all oil, natural
what are the cons of bioremediation?if the organisms die it adds an abnormal amount of nutrients to the organism, if they live they can eat things other than oil, only effective with dispersants
memorize
