Animal manure has a significant amount of nitrogen and phosphorus. These compounds are useful and valuable for agricultural systems when growing crops. However, they can be harmful when it enters the drinking water. Nitrogen, when converted to nitrate, is especially mobile and a common contaminant of groundwater.

Can animal waste contaminate well water?

Nitrate and nitrite are present in chemical fertilizers, human sewage, and animal waste and fertilizers. They can contaminate a private well through groundwater movement and surface water seepage and water run-off.

How does well water get contaminated?

Microbial Contamination

coli, crypto, and giardia are three of these more harmful kinds of microbes. They usually are found more often in surface waters like rivers or lakes. But they make their way into wells when there are heavy rainfalls or floods or if you do not properly maintain your well.

Can cows contaminate well water?

Livestock manure may infiltrate drinking water wells from field application, spills and weather events.

Can animal waste contaminate groundwater?

If not managed properly, pollutants (nutrients, ammonia, and bacteria) in manure can degrade surface water and ground water and threaten human and ecological health.

The Hidden Dangers of Plastics Pollution for Marine Animals

What are 4 things that pollute 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.

How does pet waste affect water quality?

Animal waste contains two main types of pollutants that harm local waters: nutrients and pathogens. When this waste ends up in water bodies, it decomposes, releasing nutrients that cause excessive growth of algae and weeds. This makes the water murky, green, smelly, and even unusable for swimming, boating, or fishing.

How far should livestock be from a well?

The first step that a livestock owner should take is to ensure that pastures are more than 150 feet from surface water and 50 feet from water wells. Vegetation between the pasture and the surface water should be maintained, it should be clipped so that plants are actively growing.

How far should a well be from farm animals?

Protect your well, and protect your water:

Medium and high impact activities should only occur at safe distances. Animal enclosures and septic systems should have a minimum setback of 100 feet from a domestic well.

Can cow manure contaminate well water?

Livestock manure may infiltrate drinking water wells from field application, spills and weather events.

How can I tell if my well water is contaminated?

One of the easiest ways to determine if your water is contaminated is by the smell of rotten eggs. A rotten egg smell points to sulfur bacteria or hydrogen sulfide gas in your water. Sulfur bacteria are naturally occurring. This bacteria forms through decay and chemical reactions with soil and rocks.

How common is contaminated well water?

About 1 in 8 American residents get their drinking water from a private well. And about 1 in 5 sampled private wells were found to be contaminated at levels that could affect health. CDC helps health departments reduce harmful exposures from wells.

How do I know if my well water is safe?

A nitrate test is recommended for all wells. If the nitrate level in your water is higher than the EPA standards, you should look for other sources of water or ways to treat your water. Volatile Organic Compounds (VOCs)VOCs are industrial and fuel-related chemicals that may cause bad health effects at certain levels.

What are the most common contaminants in well water?

How do you fix contaminated well water?

The Full Chlorination method kills bacteria that may be present in wells, plumbing systems and in the aquifer surrounding the well. This is the method most commonly used by well drillers for wells with persistent bacterial contamination, or for wells that have been affected by surface or flood waters.

What can you do if your well is contaminated?

If your well has been contaminated (or you think it may have been contaminated), drink bottled water or clean water from another source. If none of these options are available, follow Boil Water Advisory (BWA) guidelines to minimize the risk of contracting a waterborne illness.

What happens if an animal dies in a well?

A dead animal in your well may warrant emergency service, in which case your well technician will prioritize a visit to your home. In addition to potential water contamination, your well tech will check to see if the animal did any physical damage to your well, especially the filtration system.

Can pigs contaminate well water?

Waste from pig farms can carry pathogens, bacteria (often antibiotic resistant), and heavy metals that can be toxic when ingested. Pig waste also contributes to groundwater pollution in the forms of groundwater seepage and waste spray into neighboring areas with sprinklers.

Are farm animals treated well?

From life on a factory farm to death at a slaughter plant, animals raised for meat, eggs and dairy suffer immensely. And, as shocking as it may be, much of the abuse these animals endure is completely legal.

How far should be the distance of a septic tank from a well to prevent contamination of water?

To protect your drinking water quality, locate your septic system and all potential contamination sources as far as possible from your well. Department of Health in many States requires that new septic tanks or human-waste lagoons to be installed at least 50 feet from a well.

What is the water pollution from livestock?

Substances that originate on livestock farms and often contaminate water supplies include nitrates, bacteria, organic materials, and suspended solids.

How far from a well should a horse be buried?

Bury the animals in shallow trenches. The more shallow the burial, the less concentration of moisture that can percolate to groundwater. Do not bury the animals within 100 feet of a well. Also, any trench should provide at least five feet between the bottom and groundwater.

Can dog poop contaminate well water?

Fecal coliform bacteria can contaminate public and private drinking water supplies and can make people sick. This happens when dog waste is left on the ground and washes down into ground water or it flows with stormwater into rivers and streams that enter public drinking water reservoirs.

Does dog poop contaminate water?

Just like human sewage, untreated pet fecal matter is harmful to waterways. If “left to nature,” pet waste and the associated disease-causing organisms, such as giardia and salmonella, can be washed away by stormwater into rivers, beaches and bays via storm drains.

Does dog poop contaminate ground water?

Dog waste contains many contaminants harmful to water sources, including phosphorous, nitrogen, bacteria, and parasites. If left on the ground or near storm drains it does not go through appropriate waste treatment facilities as our home wastewater does before re-entering water sources.
