4 What is water quality? Water quality is determined by the physical, chemical, and biological characteristics of water. Water quality is determined by the physical, chemical, and biological characteristics of water.

5 Surface Runoff and its effect on water quality Surface runoff is the flow of water, rain and snow (hydrosphere). It is also a main component of the water cycle. Surface runoff is the flow of water, rain and snow (hydrosphere). It is also a main component of the water cycle. What is surface runoff? What is surface runoff?

6 Causes and effects of runoff When the water runs along the ground it picks up soil contaminations, (man-made chemicals) petroleum, (crude oil) pesticides (bug preventions, and fertilizers. These contaminants then go into our water causing its quality to decline When the water runs along the ground it picks up soil contaminations, (man-made chemicals) petroleum, (crude oil) pesticides (bug preventions, and fertilizers. These contaminants then go into our water causing its quality to decline

7 Does Elevation Influence the amount and Speed of Runoff? In areas of high elevations such as mountains, runoff effects can be more apparent in the form of flash floods and mudslides. In areas of high elevations such as mountains, runoff effects can be more apparent in the form of flash floods and mudslides. Areas around the Pasquotank are already at a low elevation. Areas around the Pasquotank are already at a low elevation. Runoff carries sediment, raising the bed level which causes increased flooding. Runoff carries sediment, raising the bed level which causes increased flooding.

8 Does the Speed of Runoff have an Impact on Water Quality? The speed of runoff has a great impact on water quality. This is because if the Runoffs speed picks up, it can pick up more sediment and man-made chemicals such as fertilizer and pesticides. The speed of runoff has a great impact on water quality. This is because if the Runoffs speed picks up, it can pick up more sediment and man-made chemicals such as fertilizer and pesticides. Forests and Swamps are much more capable of slowing water than farmlands and grasslands. Forests and Swamps are much more capable of slowing water than farmlands and grasslands. Impervious surfaces such as parking lots and roads increase the speed of Runoff because there is nothing to slow it down.

11 Does the type of soil have an Impact on Water Quality? The soil acts as a natural filter when water percolates down into the groundwater. The soil acts as a natural filter when water percolates down into the groundwater. Soil type has a significant effect as well as soil depth, and how clean the soil is, and surrounding vegetation. Soil type has a significant effect as well as soil depth, and how clean the soil is, and surrounding vegetation. Different types of soil have different rates of percolation. For example, water percolates through sand much faster than clay (this is because of the size of the soil particles; sand has much larger particles than clay). Different types of soil have different rates of percolation. For example, water percolates through sand much faster than clay (this is because of the size of the soil particles; sand has much larger particles than clay).

12 What diseases are found in water of poor quality? Cause: Source of agent in water supply Effect: Disease Sewage, non treated drinking water, files in water supply Amebiasis (hand to mouth) Collects on water filters and membranes that cannot be disinfected Cryptosporidiosis (oral) Sewage, non-treated drinking water Cyclosporiasis Untreated water, poor disinfection, pipe breaks leaks, Giardiasis (oral fecal) (hand to mouth) The genera of Encephalitozoon intestinalis has been detected in groundwater, swimming Microsporidia

13 The impact of water level on water quality When the precipitation builds up it causes an area to flood. Flooding washes materials from land (lithosphere) into the water, often causing a decline in water quality. When the precipitation builds up it causes an area to flood. Flooding washes materials from land (lithosphere) into the water, often causing a decline in water quality. High Water Levels

14 About Acid Rain Acid rain is a term used to describe how acidic materials build up in the atmosphere and return to earth in the form of precipitation. Acid rain is a term used to describe how acidic materials build up in the atmosphere and return to earth in the form of precipitation. Cause: The burning of fossil fuels creates nitric acid and sulfuric acid. Cause: The burning of fossil fuels creates nitric acid and sulfuric acid.

15 Effects of acid rain Acid rain has a negative effect on the quality of water. Low pH levels in water kills plants, diminishes oxygen and increases bacteria growth, furthermore decreasing water quality. Acid rain has a negative effect on the quality of water. Low pH levels in water kills plants, diminishes oxygen and increases bacteria growth, furthermore decreasing water quality.

16 Thermal Pollution A sudden change in water temperature A sudden change in water temperature Cause: Rainfall flows on asphalt and becomes heated and is then deposited into nearby water. Cause: Rainfall flows on asphalt and becomes heated and is then deposited into nearby water. Effects: Increased temperature results in the reduction of dissolved oxygen causing rapid growth of algae and bacteria, which in turn decreases water quality. Effects: Increased temperature results in the reduction of dissolved oxygen causing rapid growth of algae and bacteria, which in turn decreases water quality.

17 Atmospheric changes and water quality Increased amounts of sulfur and nitric oxides result in acid rain or dry deposition of these acidic particles Increased atmospheric temperatures can contribute to thermal pollution by raising water temperatures Storms that occur in the atmosphere can provide the soil with more water than it can absorb or result in increased flooding and runoff Negative Effects:

18 How does the death of animals effect the Pasquotank River? Animals such as herring, white perch, and catfish live in the Pasquotank River. Animals such as herring, white perch, and catfish live in the Pasquotank River. If one animal from the food chain dies, other animals will die because each animal lives off each other. If one animal from the food chain dies, other animals will die because each animal lives off each other. When the animal decompose in the water their body begins to decay making the water contaminated; making it unsuitable for humans to use.

19 How does the death of plants effect the Pasquotank River? Just like animals, plants have a big impact on the Pasquotank River. Plants in the river provide oxygen to the animals as well as a home. So if the plant begin to die off then that will cause the animals to die off also. Leaving the water contaminated. Just like animals, plants have a big impact on the Pasquotank River.

20 What are the effects of oil spills on water quality? Oil pollution is a growing problem, that particularly devastates coastal wildlife. Oil pollution is a growing problem, that particularly devastates coastal wildlife. Most man-made oil pollution comes from land based activity such as factories, ships, and oil tankers. Most man-made oil pollution comes from land based activity such as factories, ships, and oil tankers. When oil starts to leak into the river it harms a numerous amount of things such as the oceanic habitat and the animals living in the river, and it contaminates the water which provides the us with less drinking water.

21 What is hazardous to the water quality of the Pasquotank River? There are many things known to cause the decline of water quality such as runoff from farms which includes fertilizers, animal waste, and chemicals. There are many things known to cause the decline of water quality such as runoff from farms which includes fertilizers, animal waste, and chemicals. Dissolved oxygen occurs when organic waste consumes oxygen; making it harder for animals to live. Dissolved oxygen occurs when organic waste consumes oxygen; making it harder for animals to live. Large amounts of hazardous substances like nitric acid can kill vegetation and destroy an animals habitat.

28 Reflections These two weeks have been wonderful! Weve learned how to apply our knowledge to the events that occur in real life. Weve been to The Great Dismal Swamp, where we learned why it is important to protect our swamps. The trip to the Currituck Sound allowed us to gain hands-on experience on how scientists collect and analyze data. Through Problem Based Learning (PBL) and the Earth System Science (ESS) we have all gained invaluable skills that will last a lifetime! These two weeks have been wonderful!
