Residential & Well Water Testing for Safe, Clean Drinking Water

Your water may look clear, but harmful contaminants can be invisible. Many private wells across the United States contain unsafe levels of lead, coliform bacteria, nitrates, nitrites, and other pollutants that pose serious health risks. Unlike municipal water supplies, private wells are not routinely tested—meaning it’s up to you to ensure your water is safe.

Regular testing is the only way to detect these contaminants early. Elevated lead can damage the nervous system, coliform bacteria can signal dangerous pathogens, and high levels of nitrates or nitrites can cause severe health complications, especially for infants and pregnant women.

Most experts recommend testing your well water annually for these core contaminants to keep your household safe and healthy.

How to Test Your Home or Well Water

Testing residential water requires collecting samples from your home’s taps or well system and analyzing them in an EPA-certified lab. The EPA recommends annual testing for coliform bacteria, nitrates, nitrites, and lead. Additional testing is advised if you notice changes in taste, odor, or color.

Our inspectors follow strict chain-of-custody procedures to document each sample. Testing includes microbial and chemical analysis to check for bacteria, heavy metals, and other contaminants. This ensures your tap water testing results are reliable.
