BENEFITS OF NITRATE MONITORING
- Regulatory compliance assurance
- Blending optimization and improved efficiency
SOURCE OF NITRATE
Being highly soluble in water, nitrates can seep through the soil layers and easily reach the groundwater level. Fertilizers typically contain high concentrations of nitrates, and agricultural, residential and commercial applications of fertilizers are major sources of nitrates in groundwater. Other sources of nitrates in
groundwater are sewage disposal systems such as unmaintained septic tanks and leaking sewer pipes. It is important to monitor nitrates as often as possible in groundwater since nitrate levels can be difficult to predict and may indicate presence of other contaminants.
Nitrate is a regulated water quality parameter and the current USEPA maximum contaminant level requires that nitrate concentration not exceed 10 mg/L as N. Smart water management requires reliable and quick detection of nitrates to allow water utilities to take rapid action and protect public health against the hazards posed by nitrates.
LAB TESTING FOR NITRATES MONITORING
When nitrate analysis of water involves sending samples to a third-party laboratory, certain issues are encountered: laboratory methods are lengthy, are expensive, and samples may be compromised during transportation. The amount of time it takes to report back to the client reduces the usefulness of the information, and the extra costs associated with laboratory testing reduce the frequency of sampling. This, in turn, makes the monitoring process even more blind to the spatial and temporal variations in nitrate concentration.
CONTINUOUS MONITORING OF NITRATES
Real Tech’s real-time nitrate sensor provides far superior data both spatially and temporally by continuously analyzing the water onsite as opposed to laboratory testing methods which analyze small volumes that are widely spread over time. This allows the utility to better monitor trends and events. By continuously ensuring water quality is maintained in compliance with the regulations, real-time monitoring provides confidence and flexibility in water blending operations, and thus helps with blending process optimization. This in turn saves energy and reduces costs especially in water stressed regions.
