We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world.

ARE YOU TIRED OF WATER POLLUTION?
If you are tired of water pollution, and want a change, then here are a few things to help you understand water pollution.
What is water pollution?
Water pollution comes in many forms. The six main types are:
Surface water pollution. This is when the waters on the earth's crust become polluted.
Groundwater pollution. This is when the underground water, often used for drinking and other household things, becomes polluted, often by pesticide run-offs.
Microbiological water pollution. This is usually a natural form of water pollution. It is caused by microorganisms such as bacteria, viruses, and protozoa.
Chemical water pollution. This is caused by industrial and agricultural chemicals that run off into nearby streams, rivers, etc.
Suspended matter. This is when particles in the water have molecules that are to big to mix in to the water's molecules. This creates a layer on the bottom of the creek, river, etc, harming the fish and other marine life that lives there.
Nutrient water pollution. This is when fertalizer or other nutrient-filled substence goes into the water and causes excess algae and/or weeds grow. This causes many different problems. The weeds use most of the oxygen in the water
"Industrial processes produce toxic waste containing heavy metals."
"construction industry is also at fault for contaminating our water resources with cement, lubricants, plastics and metals."
"Natural catastrophes are the cause of water pollution effects as well."
"The growth of algae due to food items, feces, or urea in the water source is also a source of water pollution."
"Littering on the land or on the water is a source of water pollution. Debris tossed onto land eventually makes its way into storm drains and then returns to surface water."
What are some of the consequences of water pollution?
Water pollution effects all of the water that we use every day like drinking water, hose water, etc.
The pollution effects everyone and everything. If the fish get sick, the animal that eats it will get the sickness, too. Then if that animal gets hunted, then the people who eat it will get sick also!
Diseases can get spread from the polluted water when drank.
Acid rain contains harmful particles that can hurt the fish and other marine things, including the plants.
Pollutants will cause changes in the water's chemistry. It effects acidity, tempurature, and conductivity.
How can you improve the quality of the water after it has become polluted?
There are many different ways to improve the quality of the water. Industrial factories purify sewage before sending it out for people to be reused.
Denitrification is a ecological approach on water pollution. It stops nutrients from contaminating the groundwater. When the oxygen level is low, a certain type of bacteria turns the nitrates into gasses such as nitrogen, nitrous oxide, or nitrogen dioxide.
Sewage is a form of treatment that is often used for only one building. Raw sewage from the property it belongs to flows into it. It separates the solids from the liquids. Solids are separated by density (heavier particles on bottom, lighter on top). Biological processes are used to degrade the solids. The liquids then flow out into a land drainage system and the remaining solids get filtered out.
