    Drinking water solutions for the nitrate monitoring

    Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.

  • Continuous Monitoring of Nitrates and Other Water Quality Parameters

    Nitrate is one of the most important parameters in assessing surface and ground water quality. Nitrates are naturally present in surface and ground waters in low concentrations, but are harmful to humans and livestock and cause aquatic ecosystem degradation in high concentrations. Nitrates enter the environment as human-induced pollution from a variety of sources, but the largest source is from agricultural fertilizer runoff . Other sources include wastewater treatment discharge, septic systems, and from pet waste. Nitrate is highly soluble in water and therefore readily leaches into water sources, whereas other human associated pollutants, such as phosphates and ammonia, are not transported as easily. This ability to be quickly transported into ground and natural waters such as drinking water wells, aquifers, reservoirs, lakes, and streams, coupled with its health and environmental implications make nitrate pollution and monitoring of major concern.

  • Haze Monitoring

    The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.

  • Total Reactive Nitrogen (NOy) monitoring

    NOy (total reactive nitrogen) is defined as the sum of NOX plus the compounds produced from the oxidation of NOx which include nitric acid. NOy component species include NO, NO2, NO3, HNO3, N2O5, CH3COO2NO2(PAN), and particulate nitrate.

    Water quality monitoring for environmental industry

    Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.

  • Agricultural, Storm and Highway Runoff

    The ability to collect useful data about sediment transport and other pollutants closely coupled to SSC (such as nutrients, e-coli, phosphates and nitrates) is dependent on the timing and frequency of manual grab samples during run-off events. Most sediment and pollutant is transported during a small number of storm events which are infrequent and unpredictable. When they do occur, trained personnel or the proper equipment may not be available to collect grab samples. An automated pump sampler can eliminate the need to sample manually, but for the expense of a rechargeable power system, the autosampler, and possibly a datalogger and a typical turbidity probe, you’re no better off. With an automated pump sampler driven by the DTS-12 digital turbidity sensor and controlled by the Axiom H2 datalogger, you obtain a better understanding of the water’s quality, while taking a minimum number of samples, reducing site visits and saving lab analysis costs.
