This document provides information about various sources of freshwater and drinking water sources. It discusses the water cycle and major reservoirs like groundwater, glaciers, rivers/lakes and the atmosphere. Students explore these sources through various websites and activities. They learn that local drinking water in Salt Lake City comes from rivers and snowmelt in the Wasatch Mountains that flow into reservoirs in the Jordan River and Great Salt Lake watershed. The document emphasizes the importance of protecting water sources and discusses actions individuals and society can take to better conserve freshwater.

Estuaries are a type of wetland that contains brackish water. These are areas that are covered with water during parts of the year and are very biodiverse areas (contain many different species).
Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea. Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of fresh water draining from the land and salty seawater.

Water is another vital element & normally very badly managed in our society, due to our usual ignorance of its importance, characteristics & inter-relationships with other elements.
In this class we learn of harvesting systems for this vital substance, how to re-connect ourselves with the water cycle, the strategies of "slow it, spread it, sink it"
& we see various examples where a good management of water has totally changed the system. Small re-designs can improve the whole environment a great deal, & this is especially true with water re-designs.

GROUNDWATER AND SURFACE WATER INTERACTIONS
Overview
Clean drinking water is vital for all human life. In this lab, students
will learn how freshwater sources interact through the natural
processes of the hydrosphere (all the water on the planet)
and what happens to drinking water supplies when our planet
becomes altered by human activities. Students will design models
of different scenarios that affect the earth’s surface water and
groundwater. The models will demonstrate overconsumption and
dro
Background
The hydrosphere encompasses all the water
on the planet. It includes freshwater and
saltwater; liquid, solid, and vapor; and water
.
Check out our new watershed pledge for students! The Pledge will introduce your students to our watershed, nonpoint source watershed pollution, and actions they can take that prevent pollution.

Lab #10: Chemical Weathering
Purpose
In this experiment, you will learn the importance, abundance and some of the reactions of calcium and other carbonates normally found in Earth’s crust. You will explore how different types of rocks react to some of the weathering agents such as water and acid.
Materials
· Vinegar
· Lemon juice
· Water
· Clear plastic cups
· Dropper or plastic pipette
· Pieces of white chalk
· Optional- different rock types (quartz or granite)
Introduction
The Earth is not homogeneous and is composed of different layers. Each layer has a different composition. The lithosphere is the rigid outer layer that contains the crust and upper mantle. The lithosphere is composed of three equally important components, namely, inorganic (rocks and mineral), organic (soil and fossil fuel), and biological (flora and fauna). Our focus for this chapter and activity is on inorganic components.
Chemical Weathering
Rocks and mineral are all around us. Watch this video to understand the difference between rocks and minerals. Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Weathering wears away exposed surfaces over time. Chemical weathering occurs at a second stage of rock disintegration in which small pieces of rock produced by physical weathering are then further broken apart by chemical processes such acid reactions, hydrolysis and oxidation.
Acid rain is formed when certain pollutants dissolve in rain creating stronger acids. Learn more about acid rain here. Acid rain is one factor that can increase the rate of erosion, with effects that can be seen in just a few decades. Limestone and marble are composed calcium carbonate, the same material as chalk, and are commonly used for constructing buildings and statues. Rain that is too acidic will “eat away” at these structures very quickly.
Acids in rain such as sulfuric acid (H2SO4) dissolves the calcium carbonate to make a moderately soluble form of calcium, CaSO4 (called gypsum), along with carbon dioxide and water. This is an acid-base neutralization.
This could also have positive impact: the regions where the bedrock or soil contain large amounts of limestone are less likely to have polluted water due to acid rain than areas with igneous bedrock. This is because the limestone (which is a base) is able to neutralize acid rain before it gets into the lakes and rivers. This means that damage due to acid rain depends on both the pH (amount of acid in a substance) of the rain and the type of soil/bedrock.
In this activity, you will explore the effect of acetic acid (found in vinegar) and lemon juice on chalk. You can also repeat this activity with other rocks (if available) and record your observations.
Procedure
Prepare three clear plastic cups and label them as water (W), vinegar (V), and lemon juice (L). Add about 20 ml of ea ...
Overview of this wide ranging water unit. Begins with learning goals and performance expectations. Then covers the Water on Earth as a resource. Afterwards explores dwindling resources with articles of Water Woes about the Oglalla Reservoir in the midwest of the USA and Ocean animals facing extinction. Next flows through students discovering personal and national water footprints. Followed by the complete Water Cycle, research on Earth's Water crisis, Where does your wastewater go and the Pacific Salmon life cycle followed up with an overview of What's happening to salmon populations. Finally the unit ends with a lab on Salmon and water quality.
1. Where does our water come from?
Purpose: This webquestwill be done for two reasons. The first is to review what we
have learned about the water cycle before the test and see how it applies to our
lives. The second objective for this activity is for you to become more familiar with
resources on the internet and asked to analyze the information, these sites include
the USGS, GoogleEarth, NASA, EPA and others.
Part I: The Water Cycle:
1) This first step to understanding where our water comes from is to review the
water cycle. Go to the site listed below and explore the water cycle. When you
think you have an understanding of the material take the quiz (found on the
lower left side of the diagram). Then answer the question below.
http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/
Taking into account your knowledge of the Salt Lake area, where does water exist or
what are the reservoirs of water found in the local area?
Rivers, lakes, atmospheric, snow, and groundwater
In the following activities we will continues to explore the natural reservoirs
of freshwater (ground water, ice/glacial, rivers/lakes, and atmospheric) in
more detail.
2) Freshwater storage: Explore the following website to understand freshwater
storage (i.e. rivers, and lakes).
http://ga.water.usgs.gov/edu/watercyclefreshstorage.html
What are the inputs or inflows of freshwater sources?
Inputs: precipitation, snowmelt, glacial runoff, and groundwater outlets
How can surface water impact human society and where we choose to live?
Water is such a huge part of human life that typically humans must live near
freshwater. In Egypt much of the population lives near the Nile River which
provides drinking water as well as irrigation from crops. Answers will vary!
Do you think the use of surface water a good source of drinking water? Explain.
What are the disadvantages and advantages?
Answers will vary!
Pros: Easily accessible/ easy to capture.
Cons: Easily polluted, water levels/flow can be seasonal
2. 3) In this activity we will explore ground water. Go to the following webpage and
take a look around. Pay particular attention to the diagrams. Then answer the
following questions.
http://pubs.usgs.gov/of/1993/ofr93-643/
What is an aquifer?
An aquifer is a body of water in which the rock is both permeable and
porous, allowing water to easily be transported and stored in these bodies.
What conditions need to be present in order for rocks make a good aquifer? What
types of rocks are these?
Permeability and porosity
Do you think the use of ground water a good source of drinking water? Explain.
What are the disadvantages and advantages?
Answers will vary:
Pros: One of the largest and most accessible fresh water reservoirs,
clean/natural filtration
Cons: Depleting source faster than its replenished, increased pollution, can
require energy to get water to surface and finally natural pollutants (i.e.
arsenic.
4) Now explore the following webpage to learn about glaciers:
http://ga.water.usgs.gov/edu/earthglacier.html
What are the major types of glaciers?
Alpine and Continental
Explain the effect glaciers can have on the landscape?
Alpine glaciers form cirques and valleys in mountains. Whereas, continental
ice sheets will smooth the landscape. Both create potholes, moraines, and striations.
Do you think the use of glacial water a good source of drinking water? Explain. What
are the disadvantages and advantages?
Answers will vary!
Pros: Abundant source, easily captured from runoff
Cons: Not found throughout the world (only found in specific regions),
pollution (picks up pollutants from atmosphere and store them), and energy
required to capture source and transport.
3. 5) The next webpage provides information about water found in the atmosphere.
http://ga.water.usgs.gov/edu/watercycleatmosphere.html
What is the percentage of freshwater found in the atmosphere?
0.04 %
How does water move from the surface of the earth to the atmosphere. And how is
this water then transferred back to the surface?
Evaporation and precipitation. Transfer of energy
Do you think the use of atmospheric water a good source of drinking water? Explain.
What are the disadvantages and advantages?
Answers will vary!
Pros: It’s everywhere, but can be captured as rainfall
Cons: hard to capture, not consistent, polluted
6) To summarize what we have learned about the water cycle, I would like you to
carefully read the following article. Finally, write a healthy paragraph (4-6 sentences)
relating the water cycle to your life.

4. How do these relate to the water cycle?
They are all major freshwater reservoirs. Ensure students are making
connections to the previous activities
How is the water captured in each one of these sources?
Air: precipitation/rain
Groundwater: Wells, pumps and springs/seeps
Surface Water: pumps/reservoirs, diverting rivers and lakes
In the next section we are going to learn where the water in salt lake comes from.
Before we do that take a guess. Where do you think your drinking water comes
from? Briefly explain.
Rivers/snowmelt!
8) In the next section I want you to find Salt Lake City in Google earth. Once there
ensure that you are viewing the aerial photographs. Use the scale tool to zoom in and
out. While doing this note the reservoirs of water found in the local area (i.e. rivers
and lakes).
List the seven creeks that enter salt lake city from the Wasatch Mountains and
which eventually flow into the Jordan River/Great Salt Lake ?
City Creek, Redbutte, Emigration, Parley’s, Millcreek, Big Cottonwood, and
Little Cottonwood.
9) In this next activity we are going to determine where your drinking water comes
from. Open the following link. Under the “Water Program Snapshots” tab on the right
side of the screen click drinking water information. Then look at the surface water
reservoirs. Type in your address in the upper left corner.
