Sources and Extent of Groundwater Contamination The most common sources of human-induced groundwater contamination can be grouped into four categories: waste disposal practiees; storage and handling of materials and wastes; agricultural activities; and saline water intrusion.

Groundwater Contamination Chemicals and Road Salts. The widespread use of chemicals and road salts is another source of potential groundwater contamination. Chemicals include products used on lawns and farm fields to kill weeds and insects and to fertilize plants, and other products used in homes and businesses.

Contaminants Found in Groundwater Contaminants can be natural or human-induced. Groundwater will nomally look clear and clean because the ground naturally filters out particulate matter. 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.

Arsenic Contamination of Water Arsenic Contamination of Water. Arsenic is a semi-metallic element with the chemical symbol As.. It is a member of the nitrogen family, occurs naturally in rocks and soils, and can contaminate water that comes in contact with these rocks and soils. Arsenic is odorless and tasteless.

- contribute to triclosan contamination of waterways. A major source of triclosan in waterways is sew-age sludge. Triclosan accumulates in sewage sludge from municipal wastewater treatments. 25. The sew-age sludge is spread on land, and triclosan leaches down through the soil. 26. and runs off into surface water from the fields. 27. Concentrations of triclosan

What to Do If Your Cat Is Marking Territory Marking by scratching. When your cat scratches something, they're doing more than sharpening their claws; they're leaving their scent as well. Cats have scent glands on the pads of their feet, and scratching is another way cats mark territory.

In this Section: Groundwater often spreads the effects of dumps and spills far beyond the site of the original contamination. Groundwater contamination is extremely difficult, and sometimes impossible, to clean up. Groundwater contaminants come from two categories of sources: point sources and distributed, or non-point sources. Landfills, leaking gasoline storage tanks, leaking septic tanks, and accidental spills are examples of point sources.

Name three sources of groundwater pollution and how do pollutants get into the water? Removing the contaminants from the aquifer; Remediating the aquifer by either immobilizing or detoxifying the contaminants while they are still in the aquifer; Treating the groundwater at its point of use; and. Abandoning the use of the aquifer and finding an alternative source of water.

Water-related Diseases and Contaminants in Public Water Systems Sources of drinking water are subject to contamination and require appropriate treatment to remove disease-causing contaminants. Contamination of drinking water supplies can occur in the source water as well as in the distribution system after water treatment has already occurred.

Groundwater-related subsidence Mexico City subsidence. Not all groundwater-related subsidence is benign. In Mexico City, the buildings interact with the settlement, and cause cracking, tilting, and other major damage. In many places, large sinkholes open up, as well as surface cavities.

Contaminants Found in Groundwater 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. Leakage from septic tanks and/or waste-disposal sites also can introduce bacteria to the water, and pesticides and fertilizers that seep into farmed soil can eventually end up in water drawn from a well.

- Waterborne diseases can be spread via groundwater which is contaminated with fecal pathogens from pit latrines. Waterborne diseases are caused by pathogenic microorganisms that most commonly are transmitted in contaminated fresh water.

Soil contamination Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment.It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste.The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene) , solvents, pesticides, lead, and other heavy metals.Contamination is correlated with the degree of industrialization and intensity of chemical usage.aturally occurring fate of pollutants in soils. Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste.

Contamination in U.S. Private Wells Contamination in U.S. Private Wells. Groundwater is one of the Nation's most important natural resources and is an important source of drinking water for mostly-rural populations that supply their own domestic water from local wells. In 2005, about 43 million Americans supplied their own home water and over 99 percent of that water came from groundwater.

Types of Pollution Oil spills are also another source of water pollution, even on land since it can contaminate water via run off or by seeping into the ground, polluting ground water. Soil Pollution: Like air and water, the soil itself can also become polluted from dangerous materials such as heavy metals, pesticides, and landfills.
