Water Sampling & Lab Testing
Water testing is a crucial step in ensuring the safety and quality of your well water. Regular testing helps identify any contaminants, such as bacteria, nitrates, or heavy metals, that could pose health risks to you and your family. It's recommended to test your water at least once a year and more frequently if you notice changes in taste, smell, or appearance.
The water testing process typically involves collecting a sample from your well and sending it to a certified laboratory for analysis. Depending on your area and specific concerns, you may want to test for a variety of substances, including:
Bacteria: Coliform bacteria tests, including E. coli, check for harmful microorganisms.
Nitrates/Nitrites: These can come from fertilizers or septic systems and can be especially harmful to infants.
pH levels: Measuring acidity or alkalinity can help determine if adjustments are needed.
Hardness: High mineral content can affect plumbing and appliance efficiency.
Heavy Metals: Testing for elements like lead or arsenic is essential for health safety.
