Nitrates: A Key Water Quality Risk
Nitrates (NO₃⁻) occur naturally in water but can reach harmful levels due to agricultural runoff, wastewater discharge and organic matter breakdown. Accurate monitoring is essential to maintain water quality and meet regulatory limits.
Sources of Nitrates
Nitrate contamination commonly originates from:
- Fertiliser use and agricultural runoff
- Animal waste and organic matter decomposition
- Industrial discharge and wastewater treatment processes
Impact on Health and Environment
Elevated nitrate levels can have serious consequences:
- Human health: High concentrations can lead to methemoglobinemia, particularly in infants
- Aquatic systems: Excess nitrates contribute to eutrophication, causing algal blooms and oxygen depletion
- Regulatory risk: Non-compliance with nitrate limits can impact operations and water safety
Why Nitrate Monitoring Matters
Continuous nitrate monitoring enables operators to:
- Maintain compliance with drinking water and discharge standards
- Optimise biological treatment processes
- Control nutrient removal in wastewater systems
- Detect changes in water quality early
