Activity A:

Get the Gizmo ready:

Types of water pollution

 Check that the TYPE tab and Toxic pollution are selected.

Question: What are the main types of water pollution? 1. Read and learn: Besides toxic pollution, the other types of pollution are sediment pollution, nutrient pollution, and bacterial pollution. You have already described toxic pollution on the previous page. Read about the other types, and describe each in your own words. Sediment pollution Description: Sediment __________________________________________________________ pollution is the single most common source of pollution in U.S. waters.

Approximately 30% is caused by natural erosion, and the remaining 70% is caused by human activity __________________________________________________________ logging, mining, farming, and construction __________________________________________________________

Causes:

__________________________________________________________

Water polluted with sediment becomes cloudy, preventing animals from seeing Murky water prevents Consequences: food. __________________________________________________________ natural vegetation from growing in water. Sediment in stream beds disrupts the natural food chain by destroying the habitat where the smallest stream organisms live and causing massive Nutrient pollution declines in fish populations. Description:

Nutrient pollution is the process where too many nutrients, mainly nitrogen and __________________________________________________________ phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. __________________________________________________________ nutrient pollution are fertilizer, animal manure, sewage treatment __________________________________________________________

Causes:

Consequences:

plant discharge, detergents, storm water runoff, cars and power plants, failing septic tanks and pet waste. __________________________________________________________ treams, rivers, lakes, bays and coastal waters for __________________________________________________________ the past several decades, resulting in serious environmental and human health issues, and impacting the economy. Bacterial pollution

Description: While__________________________________________________________ the vast majority of bacteria are harmless or beneficial, some, like

Salmonella, cause human health problems __________________________________________________________ Causes:

__________________________________________________________

animal waste from agricultural operations, domestic pets, waterfowl, and urban wildlife, and (2) human sewage __________________________________________________________ from failing on-site sewage systems (septics), leaking sewers, or cross-connections. waterborne diseases may include gastrointestinal illnesses such as severe nausea, and possibly Consequences: diarrhea, __________________________________________________________ jaundice as well as headaches and fatigue.

Activity B: Real-world examples

Get the Gizmo ready:  Select the EXAMPLE tab.  Check that example 1/12 is selected. (If not, use the arrow buttons to get to example 1/12.)

Question: What are the real-world causes of water pollution? 1. Practice: For each Real-world example presented in the Gizmo, guess which type or types of pollution will result by checking the boxes. When you are ready, click Check answer to see if you were right. Read the explanation, and then use your own words to fill in the table. Example 1

Activity B (continued from previous page) 2. Practice: Classify each of the following examples as toxic, sediment, nutrient, and/or bacterial pollution. Explain your classifications. A. Logging removes trees from a hill, leaving a barren landscape.

Logging removes trees from a hill, leaving a barren landscape. Classification is no more vegetation on the hill to prevent sediment from being carrie Classification:There ________________________________________________________ There is no more vegetation on the hill to prevent sediment Explanation: _________________________________________________________ from being carried away B ___________________________________________________________________ B. A man washes clothes in a stream using a detergent that contains phosphorus.

nutrient pollution Classification: ________________________________________________________ Explanation: _________________________________________________________

Phosphorus in the detergent gets into the water, leading to nutrient pollution as phosphorus is a ___________________________________________________________________ nutrient C. C. At an old gas station, gasoline leaks from an underground storage tank.

Toxic Classification: ________________________________________________________ Explanation: _________________________________________________________

Gasoline, leaking from service stations, is one of the most common sources of ground water ___________________________________________________________________ pollution. D. At a research lab, a scientist carelessly pours cultures of living microbes down the drain. Classification: ________________________________________________________

It is toxic because it is going into the plumbing system

Explanation: _________________________________________________________ ___________________________________________________________________

3. Think and discuss: Many sources of water pollution are found within the home. What actions can you take to reduce water pollution? _________________________________________ _________________________________________________________________________

By making sure what I pour down the drain is safe and not and for the _________________________________________________________________________ environment _________________________________________________________________________ _________________________________________________________________________
