ES - #4 - WATER POLUTION - CHAPTER 11
What are the two types of sources of pollution?
1. Point-source pollution 2. Nonpoint-source pollution
Point-source is direct or indirect pollution?
Direct
The most common point-source pollutants are sediments, nutrients, and sewage.
False
True or false: a wastewater treatment plant that cannot handle all the incoming wastewater and discharges raw sewage into a local stream or river is a nonpoint-source pollution.
False
Nonpoint-source is direct or indirect pollution?
Indirect
96% of polluted bodies of water in the U.S. were contaminated by point-source pollution or nonpoint-source pollution.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: a restaurant's drainage pipe emptying into a river.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: chemicals added to road surfaces (salt & other de-icing agents).
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: feces and agricultural chemicals from livestock feedlots.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: litter in a storm drain.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: oil and gasoline from personal watercraft.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: parking lot runoff.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: pesticides from lawns, golf course, and farmland.
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: precipitation containing air pollutants.
Nonpoint-source pollution
Many sources of pollution?
Nonpoint-source pollution
Pollution that comes from many different sources and is difficult to identify.
Nonpoint-source pollution
Pollution that is difficult to identify is point-source or nonpoint-source pollution?
Nonpoint-source pollution
Label the following as point-source or nonpoint source pollution: a factory.
Point-source pollution
Label the following as point-source or nonpoint source pollution: leaking oil tanker.
Point-source pollution
Label the following as point-source or nonpoint source pollution: leaking storage lagoons for polluted waste.
Point-source pollution
Label the following as point-source or nonpoint source pollution: polluted water from abandoned and active mines.
Point-source pollution
Label the following as point-source or nonpoint source pollution: unlined landfills.
Point-source pollution
Label the following as point-source or nonpoint source pollution: untreated sewage
Point-source pollution
Pollution identified and traced from a single known source is ______________________________.
Point-source pollution
Single-source pollution?
Point-source pollution
Define point-source pollution.
Pollution identified and traced from a single known source.
Define nonpoint-source pollution.
Pollution that comes from many sources and is difficult to identify.
What is water pollution?
The introduction of chemical, physical, or biological agents, into water that degrade water quality and adversely affect the organisms that depend on the water.
What does water pollution affect?
The organisms that depend on water
True of false: Point-source pollution comes from a specific place that can be pinpointed as the source of the pollution contaminating a water body.
True
True or False: Runoff is generally associated with nonpoint-source pollution.
True
True or false: Nonpoint-source pollution is a combination of pollutants from a large area rather than from specific identifiable sources.
True
What are the three things introduced into water that degrade the water quality?
chemical, physical, or biological agents
List several examples of nonpoint-source pollution.
● Precipitation containing air pollutants ● Pollutants in rivers from water runoff from any watershed lands ● Chemicals added to road surfaces ● Water runoff from streets containing gasoline, animal feces, and litter ● Pesticides, herbicides, and fertilizers from lawns, golf courses, farmland ● Feces and agricultural chemicals from livestock feedlots ● Soil runoff from farms and construction site ● Gasoline and oil from personal watercraft (motorized boats, jet skis, etc.)
List several examples of point-source pollution.
● Wastewater treatment plant ● Leaking oil tanker ● Unlined landfills ● Water discharged from industries ● Leaking septic-tank systems ● Polluted water from abandoned & active mines ● Leading underground storage tanks containing gasoline or chemicals ● Leaking storage lagoons for polluted waste
