Well water is generally safe and healthy. However, any water source can be contaminated. The important thing is catching issues early so you can schedule the necessary water well services to restore clean, healthy water. Here’s a guide to some common issues to look out for. 

What Are Common Water Well Contaminants?

Bacteria

Bacteria like coliform and E. coli can get into groundwater after flooding or damage to nearby septic tanks. Bacteria contamination may come with a rotten taste, cloudy appearance, or gastrointestinal discomfort. Shocking the well with chlorine can remedy this type of contamination. 

Nitrates

Nitrates are natural chemicals found in soil. High levels are common in areas near agricultural sites, fertilizer, livestock, or ground with lots of animal waste. Nitrates do not usually affect the taste or appearance of water, so regular testing is necessary to detect high levels. Reverse osmosis or distillation filters can remove this contaminant. 

Chemicals

Chemicals often enter groundwater if pesticides or cleaning solutions are applied near the well cap. This may cause the water to taste sterile or acidic, and can cause various health issues. Reverse osmosis and charcoal filters can remove many chemical contaminants. 

Metals

Metals like lead, iron, and copper can enter well water through soil or corroding pipes. These often create a metallic taste. Metals that enter through soil can be removed through filtration, but if the pipes are corroding, they should be replaced to prevent further issues. 

How Can You Prevent Contamination?

Preventing contamination starts with securing your well. Water wells should be drilled uphill from any septic systems or structures that store fertilizer or chemicals. Additionally, inspect your well cap frequently and replace it if you notice any cracks or damage. 

Additionally, avoid applying fertilizer, pesticides, or chemicals near the well to keep these materials from seeping in. Have water tested annually to catch any issues that aren’t detectable, and schedule testing immediately if there’s flooding or you notice any change in your water’s taste or appearance.
