When their safety features fail, wastewater feeds directly into the soil to join the groundwater nearby. Primary and secondary wastewater treatment is incredibly important to ensure that water reentering the environment is safe for the community.
Visit AOS today to learn how our municipal wastewater treatment systems can help keep your locality healthy. Farms or areas that have large numbers of animals roaming free can be a problem for the groundwater. If animal waste is not cleaned up, the untreated waste can pollute the nearby groundwater the same way it would at a landfill or a sewage treatment plant.
Arsenic occurs naturally as a part of some minerals. If there is a high concentration of arsenic in an aquifer, it has the potential to contaminate groundwater and severely harm the human population that relies on it.
This type of aquifer contamination is a common problem in Pakistan, according to Science Magazine, where it has threatened up to 60 million people. Arsenic poisoning can cause developmental delays, skin lesions, cancer, and cardiovascular diseases.
The effects of groundwater contamination are far-reaching. There are five different ways that scientists measure the physical characteristics of groundwater — turbidity , color, pH, odor, and taste. Depending on what contaminates the groundwater, it will change in different ways, and cause different problems. AOS Treatment Solutions offers water analysis services to meticulously analyze your water and provide water treatment solutions to improve its safety for your community. Multimedia Gallery.

Groundwater will normally look clear and clean because the ground naturally filters out particulate matter. But did you know that natural and human-induced chemicals can be found in groundwater even if appears to be clean? Below is a list of some contaminants that can occur in groundwater.
But, natural and human-induced chemicals can be found in groundwater. As groundwater flows through the ground , metals such as iron and manganese are dissolved and may later be found in high concentrations in the water.
Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants can be human-induced, as from leaking fuel tanks or toxic chemical spills. Pesticides and fertilizers applied to lawns and crops can accumulate and migrate to the water table.
Or, a well might have been placed in land that was once used for something like a garbage or chemical dump site. In any case, if you use your own well to supply drinking water to your home, it is wise to have your well water tested for contaminates.
Some information on this page is from Waller, Roger M. Geological Survey, Want to learn more about contamination of groundwater? Follow me to the Groundwater Quality Research website! Groundwater is one of our most valuable resources—even though you probably never see it or even realize it is there. There is water somewhere beneath your feet no matter where on Earth you live. Groundwater starts as precipitation, just as surface water does, and once water penetrates the ground, it continues moving, sometimes quickly and sometimes very slowly.
Eventually groundwater emerges Learn about the quality and availability of groundwater for drinking, where and why groundwater quality is degraded, and where groundwater quality is changing. Even though the ground is an excellent mechanism for filtering out particulate matter, such as leaves, soil, and bugs, dissolved chemicals and gases can still occur in large enough concentrations in groundwater to cause problems.
How much do you know about the water below your feet? The National Water Quality Program seeks to answer four questions regarding the quality of our freshwater resources: 1 What is the quality of the Nation's streams and groundwater? Commercial pesticide applicators, farmers, and homeowners apply about 1 billion pounds of pesticides annually to agricultural land, non-crop land, and urban areas throughout the United States.
The use of pesticides has helped to make the United States the largest producer of food in the world and has provided other benefits, but has also been accompanied by concerns about their potential Groundwater is crutial to millions of Americans as well as many more worldwide. Groundwater provides drinking water to many. Thus, having reliably clean groundwater is of concern for many throughout the world.
But, groundwater can become contaminated with chemicals, biologic organisms, and other possibly-harmful agents. Artesian water is really not different from other groundwater, except for the fact that it flows to the land surface because pressure in the rocks underground force it to the surface. But, having water flow to the surface naturally is a handy way to tap groundwater resources.
Most of us don't have to look for water. We grew up either in big cities where there was a public water supply, or in small towns or on farms where the water came from wells.
But there are some people to whom finding a new supply of water is vitally important. As the salesmen sang in the musical The Music Man, "You gotta know the territory. Learn as much as possible about the land, the water supply, and the septic system of the house before buying or building.

Chemicals and contaminants in groundwater Inorganic contaminants found in groundwater Contaminant Sources to groundwater Potential health and other effects Aluminum Occurs naturally in some rocks and drainage from mines.
Can precipitate out of water after treatment, causing increased turbidity or discolored water. Antimony Enters environment from natural weathering, industrial production, municipal waste disposal, and manufacturing of flame retardants, ceramics, glass, batteries, fireworks, and explosives.
Decreases longevity, alters blood levels of glucose and cholesterol in laboratory animals exposed at high levels over their lifetime. Arsenic Enters environment from natural processes, industrial activities, pesticides, and industrial waste, smelting of copper, lead, and zinc ore. Causes acute and chronic toxicity, liver and kidney damage; decreases blood hemoglobin.
A carcinogen. Barium Occurs naturally in some limestones, sandstones, and soils in the eastern United States. Can cause a variety of cardiac, gastrointestinal, and neuromuscular effects. Associated with hypertension and cardiotoxicity in animals. Beryllium Occurs naturally in soils, groundwater, and surface water.
Often used in electrical industry equipment and components, nuclear power and space industry. Enters the environment from mining operations, processing plants, and improper waste disposal.
Found in low concentrations in rocks, coal, and petroleum and enters the ground and Causes acute and chronic toxicity; can cause damage to lungs and bones. Possible carcinogen. Cadmium Found in low concentrations in rocks, coal, and petroleum and enters the groundwater and surface water when dissolved by acidic waters.
May enter the environment from industrial discharge, mining waste, metal plating, water pipes, batteries, paints and pigments, plastic stabilizers, and landfill leachate. Replaces zinc biochemically in the body and causes high blood pressure, liver and kidney damage, and anemia.

A high concentration of arsenic has the potential to contaminate groundwater—which consuming could cause skin lesions, cancer, cardiovascular diseases, and neurodevelopmental delays Source: Sciencemag.
Arsenic poisoning from tainted groundwater has been a consistent problem in several countries across the globe. In fact, arsenic-poisoned drinking water has threatened up to 60 Million people in Pakistan.

The only option is to wait for the chemicals to be washed off from rain or irrigation—which eventually makes its way through soil and into groundwater. Septic systems, which house human waste outside of the sewage system, are typically designed with safety features in place. However, when these features fail, wastewater seeps directly into soil—and then makes its way to the water table.
On farms, or other areas with a high concentration of free-roaming animals, high levels of untreated animal waste can threaten groundwater as well. Similar to septic systems, landfills are typically designed with a safety feature in place to keep hazardous materials from seeping into the soil.
In the U. Our world runs on the hydrologic cycle.
