Transcript of Water
1. Water goes through bar
screen to filter
2. Settling chamber for smaller particles
3. Aerated to put oxygen back into the Water
4.Finally put into irrigation or to your local school or park Septic Tanks Some septic tanks are made of plastic. Septic tanks are what carry sewage from your house/ business to a river or ocean. 2/8/13

1. After aerating it goes into
another settling tank
2. Chlorine tank
3. Put back into lakes and rivers poop=pee Water pollution caused by agricultural practices are among some of the highest around. So here are a few solutions to do with anything and everything Agro. Slow Release Fertilizer •Slow-release fertilizers hold nutrients available to crops for months at a time.
Which decreases the need for “quick release fertilizers” (fertilizers that are consistently sprayed) and therefore lessen the chance of build up that can run off into surrounding surface waters.
Slow release fertilizers are also not soluble, this means they cannot dissolve into liquids (mix with water), and there is a decreased chance for water pollution. Option #1 Organic Filtration Option #2 Using No Fertilizer 1.The raw sewage passes through tanks filled with algae
2. Then passes through an artificial marsh made of dirt, gravel and bulrushes. This method is most commonly applied on steeply sloped land Buffer Zones Option #3 3. Next the water goes into an aquarium tank ten days and is eaten by organisms that are then sold as bait and food.
4. After that the water goes into a second artificial marsh for final clarification. •The planting of zones of vegetation between cultivated fields and nearby surface waters These buffer zones are made up of a collaboration of various plants (trees, shrubs, grasses) that are organized to catch and filter potential water pollutants headed towards sources of water Option #4 Organic Farming 5. The water then can pass through UV lights, or an Ozone generator to make it drinkable. •Organic farming aids the prevention of water pollution as a side effect of commercial inorganic farming Which uses fertilizers and pesticides that nutrient overload the soil and run into nearby surface water, as well as animal waste storage from pastures and feedlots. Solutions and Laws Bio fertilizers are fertilizers made up of biological waste (waste found in nature) and does not contain any chemicals that could potentially harm and run into water But it uses Fertilizer! Standard Filtration By: Jackson Septic Tanks By:Spencer Solutions to Water Pollution Clean water act Started 1948 it was called the federal water control act and expanded in 1972 then was called the clean water act. Sets standard on how much pollution you can put into the water, and the polluters have to have permits. It led to better water quality in the U.S. •Annual wetland losses decreased by 80% Safe Drinking water act Started in 1974 and it was amended in 1986 and 1996. This act was made to protect the drinking water and its sources rivers, reservoirs, springs, and ground water wells, but it doesn't apply to those with their own private wells. SDWA (safe drinking water act) made the United States environmental protection agency set national health based standards for drinking water to protect against contaminants that can be found in the water. Shore Protection Act The shore protection act Started in 1988. This act prohibits the transportation of commercial waste within coastal waters without a permit. The main goals are to minimize the deposit of waste when into coastal waters during vessel loading, transport, and unloading, and make sure deposited is reported and cleaned up. Water
