How Does Nitrate Get Into Groundwater?
Nitrate can reach groundwater from fertilizer, manure, septic systems, sewage, and some natural deposits. You cannot depend on taste, smell, or color to warn you. Nitrate has a drinking-water standard because high levels can quickly harm infants. A result above the standard needs the required response. Use the bottle, sample point, cooling, and delivery steps set by the lab. Keep the bottle away from fertilizer and dirty coolers. Compare a rising result with older results from the same well and season. Review rain, pumping, and nearby land use. Do not average away a high result. Only a valid lab test can show compliance. Follow the system and regulator plan for notice, more samples, or other action.
Key point: never delay required notification or response while waiting for visible evidence of nitrate contamination.
