Groundwater pollution is difficult to clean up because aquifers recharge slowly and because pollutants cling to the materials make up an aquifer. Groundwater is polluted by many different sources so it is hard to control all the pollutants.

What are the consequences of over pumping groundwater?

Pumping has removed water from storage in basalt aquifers and caused declines in many areas of the Columbia Plateau. The most severe consequence of excessive groundwater pumping is that the water table, below which the ground is saturated with water, can be lowered.

Where does most of the pollution in the ocean come from?

Most ocean pollution begins on land. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.

What is vapor intrusion?

Vapor intrusion is the general term given to the migration of hazardous vapors from any subsurface vapor source (i.e., contaminated soil or groundwater) into the indoor air of an overlying building or structure. These vapors can enter buildings through cracks in basements and foundations, as well as through conduits and other openings in the building envelope. All types of buildings, regardless of foundation type (e.g., basement, crawl space, slab-ongrade), have openings that render them potentially vulnerable to vapor intrusion.

When restoration of groundwater to beneficial uses is not feasible, what does the EPA expect?

When restoration of groundwater to beneficial uses is not feasible, EPA expects to prevent further migration of the plume, prevent exposure to the contaminated groundwater, and evaluate further risk reduction.

What is a superfund response?

Superfund responses to contaminated groundwater generally address all exposure pathways that pose an actual or potential risk to human health and the environment. For example, groundwater response actions should generally address the actual or potential direct contact risk posed by contaminated groundwater (e.g., human consumption, dermal contact or inhalation), and should also consider the potential for the contaminated groundwater to serve as a source of contamination into other media (e.g., sediment, surface water, wetlands, or vapor intrusion into buildings).

How does pumping water work?

Pumping draws contaminated water toward the wells, keeping the contaminant plume from spreading. This pumping helps keep contaminants from reaching drinking water wells, wetlands, streams, and other natural resources. In situ treatment occurs when groundwater is treated in place without extraction from the aquifer.

What is an alternative water supply?

Alternative water supply: EPA can provide drinking water and household water supplies under Superfund when drinking water wells or a principal drinking water supply become contaminated. Providing an alternative water supply may involve furnishing clean, drinkable water on a permanent or temporary basis. Examples of providing a permanent drinking water supply include installing a new private well, connecting to a municipal water system, or drilling a new community water supply well. Examples of providing a temporary water supply include installing individual treatment units or delivering bottled water.

Does Superfund clean up groundwater?

Superfund prefers to treat contaminants to reduce their toxicity, mobility or volume. As part of the overall site cleanup, groundwater remedies may be combined to clean up groundwater contamination. Groundwater remedies may also be used with other remediation technologies to address different media, contaminants, or contaminant levels.

Why Does it Take so Long to Remove the Contaminants from the Water?

Most contaminants are water soluble, meaning that they dissolve in water. Water sources can dilute contaminants to a concentration that may not be dangerous. However, after enough pollution, the capacity of the lake, river or stream can be exceeded. The retention time, or residence time, of a water body is the time that it takes for a substance that is introduced to the water to flow out again. The retention time of a lake can vary, depending on the volume of the lake, the depth of the lake, and the number of rivers flowing in and out of the lake. While some lakes have retention times of only several months, there are others that retain substances for several thousand years. The following chart summarizes the retention times of several lakes.

How are industrial and agricultural pollution practices minimized?

Unfortunately, industrial and agricultural pollution practices are generally not minimized until government regulations are developed to set limits on air and effluent emissions. The regulations typically determine the amount of pollutants that can be emitted, as well as how and where wastes may be disposed of.

How can cities reduce water pollution?

Cities can reduce water pollution by upgrading their wastewater treatment facilities. Most urban centres have wastewater facilities with secondary treatment processes, but installing a tertiary treatment process can remove phosphorus, which is responsible for excess algae growth.

How does air stripping work?

Air stripping is a method that uses air to remove contaminants from water. This process can effectively remove chemicals that evaporate easily, including fuels and solvents. Contaminated water is pumped through a large chamber, where it is sprayed over packing material. The packing material allows the water to slowly trickle to the bottom of the tank. At the same time, a fan blows air upwards, which causes the chemicals to evaporate out of the water. The chemicals are collected at the top of the tank, and treated, so that they cannot cause further pollution.

What is the most beneficial action that individuals can take?

The most beneficial action that individuals can take is to reduce pollution within their own lives. Using less and proper disposal of harmful substances can go a long way in removing or minimizing sources of water pollution.

How long does it take to clean up groundwater?

The time required to clean up a groundwater source with this method ranges from a few days to years, depending on the rate and success of other treatment methods. These processes are extremely expensive, with the prevention of the pollution in the first place being hundreds to thousands of times less expensive.

Contaminants Found in Groundwater

Groundwater will normally 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.

Microbiological contaminants found in groundwater

Occur naturally in the environment from soils and plants and in the intestines of humans and other warm-blooded animals. Used as an indicator for the presence of pathogenic bacteria, viruses, and parasites from domestic sewage, animal waste, or plant or soil material.

Some information on this page is from Waller, Roger M., Ground Water and the Rural Homeowner, Pamphlet, U.S. Geological Survey, 1982.

What is the process of cleaning groundwater in an aquifer?

Cleaning groundwater in an aquifer requires bioremediation or chemical remediation. Bioremediation uses microorganisms to consume a pollutant. Chemical remediation destroys the contaminant.

What is the name of the process of treating water in the aquifer?

Bioremediation is one way of treating the water in the aquifer. Microorganisms are bioengineered to eat the pollutant. The organisms are injected into the contaminated region. They consume the pollutant. Bioremediation is short for biological remediation .

How to clean groundwater?

To clean groundwater: remove the pollutant source, monitor the pollutant, and perform remediation. Scientists test the water in many wells to see where the contaminant is. They do this to tell where the contaminant is. Over time they can tell which direction the contaminant is moving .

What can pollute surface water?

Pollutants in surface water can filter into the ground and enter a groundwater aquifer. Irrigation water can bring pesticides and other chemicals. Water can seep through landfills. Tanks of gasoline stored underground can leak.

How do scientists monitor the extent of the pollutant?

Monitor the extent of the pollutant: Scientists test water in wells. Sometimes they drill wells to test water. They learn how the groundwater is flowing: how fast and in what direction. They study the contaminants in the groundwater. Then they determine where the contaminant plume is going.

How does chemical remediation work?

Chemical remediation can also treat water in the aquifer. A chemical is pumped into the aquifer. The chemical destroys the contaminant.

How to eliminate pollution?

Eliminate the pollution source: An underground tank must be pumped dry and then dug out from the ground. A factory must be required to stop releasing toxic chemicals. Farms must be more careful about the chemicals they put on their fields. Monitor the extent of the pollutant: Scientists test water in wells.

How can we encourage companies to clean up their practices?

Instead of being discouraged by the amount of trash and contamination there is to clean up, we can encourage companies to clean up their practices through legal incentives (including fines) to prevent additional pollution. Keeping each other well informed about existing polluters is key.

What is the best solution to pollution coming from agriculture?

The best solution to pollutants coming from agriculture is what German water utilities are doing. They are saving money by paying farmers to switch to organic farming—which is cheaper for them than trying to clean up pollution caused by pesticides, herbicides, chemical fertilizers, and other pollutants industrial farmers use.

Why did the government pass the Clean Water Act?

Because the public recognized the danger of this kind of pollution much faster than they did ocean pollution, in 1977 we pushed the government to pass and enforce the Clean Water Act. This was intended to prevent additional pollution and also to enable the government to help clean up existing pollution.

Why is raising children important?

Raising children with these values is a role that parents can play to help clean up our polluted environment. Instead, people who did grow up responsibly are forming teams all across the world to manually clean up non-toxic pollution that washes up onto river banks.

Why is it important to switch to organic farming?

Switching to organic farming can take care of pollution caused by agribusiness, which is major, especially of our waterways. However, there are lots of other types of polluters out there too.

What does it mean to clean up after yourself?

to treat each other and you with respect , the value of hard work and love for the environment, and. to clean up after themselves—they can play and get as messy as they want to, but they have to clean up after they've finished. If corporate leaders were to grow up expecting to have to clean up after themselves, we would have far less pollution ...

What percentage of lakes are unsafe for fishing?

Here is the end result when children who grow up irresponsibly become adults: 40% of U.S. lakes, rivers, and streams are unsafe for fishing or swimming, per the Environmental Protection Agency (EPA), even after passage of the US Clean Water Act in 1977. US President Trump later gutted that act.

Why is the entire body of water considered contaminated?

The reason the entire body of water is considered contaminated after it has been discovered that a contamination has occurred is that the polluting factor will create a plume in the aquifer. A plume occurs when the movement of the groundwater pushes the polluting factors down into the entire body of water.

How does groundwater become polluted?

So, how does groundwater become polluted? Groundwater becomes polluted when contaminants are discharged into the ground and travel directly down to the groundwater’s level.

What are the best ways to clean contaminated groundwater?

Groundwater biological treatment techniques include bioaugmentation, bio venting, bio sparging, bio slurping, and phytoremediation.

What are the sources of groundwater pollution?

Some sources of groundwater pollution can come from many different resources, such as sanitation systems, landfills, water waste, plants, leaking sewers, fertilizers, and much more. If the sources of groundwater become naturally contaminated, chances are it was contaminated by arsenic or a fluid that has somehow seeped into the ground.

Why does ground water move faster?

The reason for this is ground water can move a lot quicker through unseen aquifers and reach greater lengths without being detected. However, nonporous aquifers such as clay can partially clean the contamination through a natural filtration process.

When contamination occurs, it is time to begin the groundwater remediation process?

When contamination occurs it is time to begin the groundwater remediation. Ground water remediation is the process of cleaning out the water. However, the main problem with groundwater contamination is how difficult it is to treat. It is a lot more difficult to treat groundwater than it is to treat surface water.
