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.
Measuring groundwater level or depth-to-water is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water. Receiving groundwater data via remote data transmission from one of the many OTT telemetry options available saves time and resources spent in the field.
Urban Hydrology deals with the specific aspects of the hydrological cycle in urban and industrial settings. This includes all natural water flows as well as the consideration of precipitation, storm water, groundwater, rivers, and lakes, but also the infrastructure and systems for water supply and sanitation in a city.
Naturally occurring organics in raw water are typically removed with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when generic organic material is present but cannot differentiate between natural organics, such as algae or decomposed plant matter, and hydrocarbons. Using UV fluorescence technology, a properly configured TD-4100XD can alert operators to upsets caused by hydrocarbons such as gasoline, diesel, fuel oil, and crude oil.
Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream ecosystem interfaces provides a mechanism for detailed characterization...
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.
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.
Turbidity in natural waters is recognized as an important indicator of its environmental health, and because it's a good surrogate for suspended sediment, monitoring turbidity has always been the "holy grail" for hydrologists. But because of earlier technology, "turbidity" has traditionally been a "bad word". The DTS-12 turbidity sensor is the first sensor to make turbidity monitoring practical, and no longer difficult, inaccurate, expensive, or labor-intensive.
Turbidity is the cloudiness or murkiness of water...

Based on the wireless radar technology SenZ2 provides a complete solution for remote, real-time monitoring and logging of water levels. For the water sector real-time insights in water levels is key. Accurate level-measurement data can result in improved policy, reduction of risks and direct cost savings. The Wireless Level Radar (WLR05-2G/001) can monitor waste water and overflow, surface water and groundwater in remote places without any power source. With radar as the most reliable and cost-effective level...
