Nitrate Water Testing
and Clinics

TV Monitor.jpg

Private wells should be tested for nitrate every other year. Nitrate occurs naturally and at safe and healthy levels in some foods (such as spinach and carrots) and comes from natural processes, such as plant decay. High levels of nitrate in water can be a result of runoff or leakage from fertilized soil, wastewater, landfills, animal feedlots, septic systems, or urban drainage. 

You will need to bring a fresh, water sample (taken within 1 day of analysis) with you. To take your sample, run your cold tap for five to ten minutes then collect about one cup of water in a plastic baggie (double bag) or clean jar. Keep the water cool until arrival.
