Continuous monitoring of nutrient levels provides crucial information about daily, seasonal and event based changes in water quality conditions, and can be a strong indicator on the overall health of the water body. In recent years, monitoring of nutrients has grown in importance as it has come to the forefront in regulatory compliance of water quality in many regions.
Measuring water quantity and quality in surface water (open channels, rivers, reservoirs, lakes, and estuaries) is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first water current meters were designed in 1875.
Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-bird Coastal offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications.
The technology of Spectral Fluorescence Signatures (SFS) is a very sensitive and selective tool to monitor many industrial processes on site and in real-time. The SFS analyzer series – SFS-Scanner and Instant Screener spectrofluorometers - are capable of detecting target substances even in complex mixtures without any pre-treatment of the samples.
Being one of the key necessities of life, water should be submitted to a thorough quality control. Targeted chemical analysis of priority compounds can give an impression of the chemical quality, but may not cover the entire load of pollutants that evoke biological effects. CALUX assays are successfully applied in the identification of water samples that are polluted with biologically active toxicants even at low levels and address the complexity associated with the compound mixtures.
Boost operational efficiency, prevent fracking water contamination and ensure regulatory compliance at your shale oil and gas site. In-Situ’s EPA-approved fracking water quality technologies help you achieve best practices at lower cost, protecting your company and water resources.
MANTECH’s game-changing water quality analysis technology is revolutionizing wastewater treatment at industrial and municipal facilities worldwide. The PeCOD Analyzer provides accurate chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates within minutes rather than the hours or days required for standard COD and BOD testing — without the use of dichromate, mercury, acids and other harmful chemicals.

Water abstraction points may be affected by spills from farms or factories, and deliberate contamination. Early warning monitoring systems are required to alert operators to these contaminants and to changes in key water quality parameters. A timely response is necessary to prevent contamination and disruption of the public water supply.
Chelsea Technologies Group has developed FastGuard to observe the natural trends in water quality parameters and rapidly detect and report anomalies.

Several on-line monitoring technologies such as non-destructive types have become increasingly important due to the increasing automation and the incorporation of new and more efficient processes in the food industry. Food quality and safety of food are the main points of interest, while adjacent processes such as process water and waste water treatment present new challenges to larger food companies.
