Five Toxins to Test For if You Have Well Water

As you probably already know, drinking water can pose risks due to harmful pathogens and pollutants. Public water systems employ measures like water treatment and constant monitoring to safeguard against contaminants, but private wells don’t undergo the same level of protection. If you own a private well supplying your household with drinking water, it’s your responsibility to ensure its safety. Regularly testing your well water for harmful substances is crucial to prevent potential health risks.

Today, we’re going to discuss five key toxins you should test for if you rely on well water. Wells can become contaminated in many ways, exposing your water to a range of harmful elements. Consistent testing is essential to stay ahead of potential issues and maintain safe drinking water.

Bacteria

One of the first things to check for in your well water is bacteria. Total coliform bacteria are often the primary focus for private well owners. The CDC notes that coliform bacteria are commonly found in animal digestive systems, plants, soil, and surface water. Detecting coliform bacteria can signal vulnerability to surface contaminants seeping into the aquifer. Although coliform bacteria itself isn’t inherently harmful, it might indicate the presence of disease-causing pathogens. Therefore, it's a good idea to conduct an E. coli test alongside the coliform bacteria test.

Arsenic

Arsenic, a naturally occurring element found in rocks and soil, can infiltrate groundwater. Exposure to arsenic can lead to serious health concerns, affecting the digestive, respiratory, and nervous systems. It can also harm the liver and skin. Mild symptoms of arsenic poisoning include facial swelling, nausea, stomach pain, diarrhea, and vomiting. More severe cases may result in internal bleeding, coma, or permanent nerve damage.

Arsenic enters well water through natural geological processes. As groundwater moves through soil and rock containing arsenic, some arsenic dissolves into the water. It’s highly recommended to regularly test your well water for arsenic. Levels can fluctuate seasonally, so experts suggest testing twice a year—once in late summer and again in early spring—to monitor any changes.

Nitrate

Nitrate, a compound commonly found in fertilizers, manure, and septic tank effluent, can contaminate private well water. Rain or irrigation water carries nitrate through the soil into the groundwater supply. If your well taps into this groundwater, your drinking water may contain nitrate.

High nitrate levels in water can lead to various health issues, particularly affecting oxygen transport in red blood cells. While most adults and children recover quickly, infants are at greater risk. Consuming water with high nitrate levels can lead to a condition called methemoglobinemia, or "blue baby syndrome."

Older, improperly sealed, or poorly constructed wells are especially prone to nitrate contamination. It’s advisable to test your water annually. Contact your local health department for testing locations and additional advice. If your nitrate levels exceed 5 mg/L, consider retesting within six months.

Manganese

Manganese is a naturally occurring mineral found in rocks, sediment, and soil. Although it’s beneficial in foods like grains and vegetables, drinking water containing manganese in concentrations above 0.5 parts per million can be harmful to humans. Removing manganese from water is challenging because its removal depends on factors like oxidation state, other minerals present, water pH, and total dissolved solids.

Research suggests a connection between manganese in drinking water and neurological issues in infants and children, such as behavioral changes, speech and memory difficulties, lower IQ, and impaired motor skills. Black stains on your shower, laundry, or plumbing fixtures may indicate the presence of manganese. To test your water, consult a certified drinking water lab. You can find a list of certified labs near you on the EPA’s website.

Lead and Copper

Lastly, you should also test your well water for lead and copper. These metals are naturally occurring but usually enter well water through older plumbing systems. Replacing old pipes is an effective solution, though costly for some. Flushing the system for a couple of minutes before use may be a more budget-friendly option.

According to the EPA, exposure to lead and copper in water can cause a range of health issues, from stomach discomfort to brain damage. To test for these metals, consult your local health department or nearby water utilities for guidance on regional contaminants. Testing costs typically range from $20 to $100, but this investment provides peace of mind.
