The specific bioindicator we used were macroinvertebrates. What is a macroinvertebrate?
large enough to be seen without a microscope with no backbone (bugs)
any bioindicator
nitrates
any living things in the water
What piece of equipment do we use to measure turbidity?
a chemical test
bioidicators
a secchi disk
incision ration
What is salinity?
The property of containing salt
The amount of suspended solids
Describes the condition of the water
Describes how acidic or basic water is
Where are nitrates and phosphates found?
Fertilizer
Manure
Detergent
All of the above
Why are too many nutrients (like nitrates and phosphates) bad for our waters?
Nutrients decrease the pH of the water, causing it to become increasingly acidic
Nutrients change the salinity of the water
Wetlands filter out runoff that may contain nutrients
Nutrients in the water cause too much algae growth, which decrease the level of oxygen in the water
What is pH?
The property of containing salt
The measure of the amount of oxygen that is dissolved in water
The amount of suspended solids in water
The measurement of the acidity or basicity of water
Which glass contains water with high turbidity?
Glass 1
Glass 2
pH value of less than 7 is considered to be
polluted.
basic.
like drain cleaner.
acidic.
pH greater than 7 is considered to be
neutral.
basic.
acidic.
polluted.
Temperature of the water impacts
what kind of organisms can live in rivers, creeks and lakes.
the amount of dissolved oxygen.
the amount of minerals dissolved in the water.
all of the above
Too far above or below a preferred range of temperature will
decrease the number of individuals in a species.
increase a plant's ability to do photosynthesis.
not matter because we did not measure this.
not act as limiting factor.
Cold water holds more dissolved oxygen than warm water.
True
False
A watershed is
just the French Broad river and the land that surrounds it
an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel.
not usually impacted by humans.
a small building that contains a water pump.
Which of the following IS NOT true about groundwater?
Groundwater is the largest freshwater source on Earth.
Groundwater is freshwater beneath Earth’s surface.
Groundwater is the largest liquid freshwater source for humans.
Groundwater can maintain streamflow during times of drought.
Any moisture found in the soil is considered to be groundwater.
True
False
Which of the following implies the same thing as the word "aquifer"?
zone of saturation
zone of aeration
zone of soil moisture
zone of twilight
The top of an aquifer is known as:
the water table.
an artesian well.
the hydraulic gradient.
a geyser.
Which of the following are wells used for? CHOOSE ALL THAT APPLY!
Wells are used to determine the height of the water table.
Wells are used to obtain water for crop irrigation.
Wells are used to obtain water for human consumption.
Wells are used to create barriers between aquifers, called aquatards.
A place where the water table meets the ground surface and where a natural flow of groundwater results is called:
a spring.
a geyser.
an aquatard.
a fissure.
What is the most common method for removing groundwater?
a well bored into the zone of saturation
accessing the water table by use of low-grade explosives
building a water tower
damming up a river
Which of the following depicts an artesian well?
Which of the following is a hydrological problem currently facing the High Plains of the United States?
over-pumping of the Ogallala aquifer
compaction of the San Joaquin valley
mass amounts of human contamination seeping into the aquifer
flooding of Lake Mead
What is infiltration?
The process by which water sinks into the ground
The zone where there are still air spaces left between the particles.
The process by which water vapor turns into liquid water and forms fog or clouds.
The process by which water does not sink into the ground, but rather travels along the surface.
Which surface would be impermeable?
The water is able to flow the pore spaces, what type of rock is it?
permeable
impermeable
aquifer
geyser
If water is not able to flow through the rock, the rock is?
permeable
impermeable
geyser
aquifer
What is a geyser?
A place where groundwater is superheated which builds pressure and causes shooting hot steam in the air.
A cold spring that creates a fountain
a type of spring
None of the Above
Water collects in an aquifer because the layer below it is
permeable (water can pass through it)
impermeable (water can not pass through it)
transparent
True/false: Almost everything that happens on land, has an impact on surface water and groundwater.
true
false
Runoff picks up whatever is on the ground including
fertilizer and pesticides
household chemicals and soap from washing cars
chemicals from factories
oil
all the above
Sources of water pollution include all of the following EXCEPT:
Suburban homes
Farms and golf courses
Parking lots and city streets
Water treatment plants
Factories
How can air pollution from cars and factories end up in our water??
Oil drips from cars onto roads
Air pollutants can dissolve in rain water
We use soap to wash cars
How can you help reduce water pollution?
Use less fertilizer and pesticides
Take paint, cleaners, and old medication to safe disposal sites
Clean up pet waste and litter
All the above
