Water Quality & Potability Testing in Greater St. Louis
Proudly Providing Inspection Services for St. Charles, O’Fallon, St. Peters, Wentzville, Harvester, and the Greater St. Louis Area
Access to clean and safe water is one of the most important necessities to living a healthy life. Just because your home’s water appears to be clean and clear does not mean that it is free from potentially harmful contaminants.
In Missouri, water quality is tested to ensure it meets safety standards and protects public health. The state requires testing for E. coli and coliform bacteria, as these bacteria can signal potential contamination and pose health risks. The only way for homeowners to have confidence in their home water supply is through a Water Quality Test conducted by a certified professional. Contact your local NPI inspector to order a Water Quality Test today!
Why Test for E. coli and Coliform Bacteria?
These bacteria are commonly used as indicators of fecal contamination in water, which could lead to waterborne diseases like diarrhea and stomach cramps. Missouri’s water quality standards require testing to ensure these bacteria are not present in drinking water.
We Can Test for More Than Just Bacteria
In addition to routine testing for E. coli and coliform bacteria, we also offer testing for other common contaminants that can affect water quality, including:
- Lead: Dangerous for both children and adults, often found in old plumbing systems.
- Nitrates & Nitrites: Typically from agricultural runoff, these chemicals can be harmful, particularly to infants.
- Other Chemicals: We also test for a range of harmful chemicals that could affect water safety.
What Can Cause Water Supply Contamination?
While come water contamination will be obvious, seemingly clear water can contain harmful contaminants. The Environmental Protection Agency (EPA) recommends annual water supply testing, and homes with more vulnerable occupants (e.g., infants or seniors) should test more frequently. External forces can compromise previously clean water, and homeowners should regularly test their water supply to ensure their ongoing safety. Here are some situations that can result in water contamination:
- Outdated or damage municipal plumbing systems
- Nearby mining activity (like fracking)
- Nearby agricultural activity (or livestock farming)
- Nearby business operations (like dry cleaning, gas stations, or industrial operations)
- Recent natural disasters (especially flooding)
- Ground water contamination
- Manure runoff and pet waste
