As many of us are aware, drinking water can sometimes introduce a range of harmful pathogens and pollutants into our daily lives. Public water systems often employ proactive measures like water treatment and monitoring to shield us from these contaminants. However, private wells don't receive the same level of care. If you own a private well that provides drinking water to your household, you hold the responsibility of ensuring its cleanliness. To guarantee your well water remains free of harmful toxins that could pose risks, you need to be mindful of your well's potential contamination sources and the health impacts these contaminants might bring.
Today, Office H2O is going to discuss five toxins—or contaminants—you should test for if you rely on well water. Wells can become contaminated in numerous ways, allowing various toxins to seep into your water supply. Regular testing is key to maintaining clean, safe drinking water. It’s the best way to stay proactive about keeping your well water pure.
Let’s start with bacteria. The first thing you should check your well water for is bacteria, particularly total coliform bacteria. According to the CDC, coliform bacteria are found in warm-blooded animals' digestive tracts, on plants, in surface water, and soil. A positive test for coliform bacteria suggests that your well might be vulnerable to surface contaminants seeping into the aquifer. Though coliform bacteria themselves aren't necessarily harmful, they could signal the presence of disease-causing pathogens in your water. Therefore, it's a good idea to conduct an E. coli test alongside a coliform bacteria test.
Next up is arsenic, a naturally occurring element found in rocks and soil. Arsenic can leach into groundwater, posing serious health risks, including issues with digestion, respiration, and the nervous system. It can also harm the liver and skin. Mild symptoms of arsenic exposure include facial swelling, nausea, stomach pain, diarrhea, and vomiting. Severe cases can lead to internal bleeding, coma, and permanent nerve damage.
Arsenic enters well water through natural geological processes. When groundwater flows through arsenic-rich rocks and soil, some of the arsenic dissolves into the water. Experts recommend testing your well water for arsenic regularly. Since the concentration of arsenic can fluctuate seasonally, it's advised to test once in late summer and again in early spring to detect any seasonal variations.
Moving on to nitrate, a chemical commonly found in fertilizers, manure, and septic tank discharge. Natural bacteria in the soil can also convert nitrogen into nitrate. Rain or irrigation water can carry nitrate down through the soil into the groundwater, potentially contaminating your well water. High nitrate levels can reduce the ability of red blood cells to transport oxygen, leading to conditions like methemoglobinemia, or "blue baby syndrome," especially in infants.
Shallow wells, improperly sealed wells, or poorly constructed ones are at the highest risk of nitrate contamination. It's strongly recommended to test for nitrate annually. Your local health department can guide you on where to get your water tested and may provide specific recommendations. If your nitrate levels exceed 5 mg/L, consider retesting in six months.
Another contaminant to watch out for is manganese, a naturally occurring mineral found in rocks, sediment, and soil. While manganese is beneficial in food, it can be harmful in drinking water, even in low concentrations. Removing manganese from water can be challenging due to factors like its oxidation state, the presence of other minerals, water pH, and total dissolved solids. Studies suggest a link between manganese in drinking water and neurological issues in infants and children, including behavioral changes, memory problems, lower IQ, and poor motor skills. Signs of manganese in water include black stains on showers, laundry, and plumbing fixtures. You can have your water tested for manganese by contacting a certified drinking water lab. The EPA provides a list of certified labs on their website.
Lastly, we have lead and copper. These metals aren’t usually found in groundwater but can enter well water through older plumbing systems. Replacing old pipes can solve this issue, though it can be expensive. Alternatively, flushing your water system for a couple of minutes before use might be a cheaper option. Exposure to lead and copper can lead to health problems like stomach discomfort and even brain damage. The EPA suggests checking with your local health department or nearby water utilities for regional contamination concerns. Testing costs around $20 to $100, but it’s a worthwhile investment for peace of mind.
For those seeking peace of mind regarding their drinking water, Office H2O offers bottleless water systems. While these systems might not eliminate all toxins, they use advanced technologies like reverse osmosis filtration to enhance water quality. Our systems are eco-friendly and cost-effective, ensuring you and your family enjoy fresh, clean water every day.
Remember, safeguarding your well water is crucial for your family's health. With the right tools and knowledge, you can ensure your water remains safe and pure.
