Water has always been present on Earth. water is in clays,comets and Some water form in vapor and ice crystals, has always been present in the atmosphere of the Earth. Water vapor is also released from the Earth's interior by volcanoes.
keeping pollutants out of the water is important. People from Iowa and from other parts of the world depend on clean water for drinking water also water animals like fish depend on clean water to survive.
Pollution in Iowa happens when rainfall, snowmelt or irrigation water runs over land or through the ground and picks up pollutants and deposits them into streams, lakes or groundwater. Those pollutants include excess soil, bacteria and nutrients from farm fertilizers and manure.
pollution in Iowa may come from agricultural or urban areas, construction sites, roads, parking lots and other areas. Other common pollutants include pesticides,bacteria and viruses. In Iowa sediment is the leading nonpoint source pollutant. Most sediment in Iowa comes from agricultural practices such as livestock in pastures, woodlands and feedlots. sediment come from construction sites streambanks and lake shorelines.In Iowa nitrogen and phosphorus are also nonpoint pollutant. fertilizers on agricultural land and on residential lawns like golf courses and from organic sources such as manure and human sewage.
water pollution is the cause unsafe wildlife habitat and unsafe drinking water, fish kills. water pollution from human sewage can cause health problems. it can also can cause algae blooms in lakes, sometimes making lakes smelly and boating difficult. lawn chemicals can also cause water to be unfit for drinking.
Solutions----
better water better life.....
better water better life.....
The main solution is to keep out excess sediment, nutrients, bacteria and other pollutants out of our water. Because the largest problems come from agricultural areas. conservation practices include wetlands, ponds. These practices reduce the amount of pollutants reaching a lake or stream. Agriculture is the largest source of nonpoint pollution in Iowa, urban areas can work to improve our water
