Environmental Water Quality Monitoring

Water quality is critical to environmental and ecosystem health. By monitoring water quality, researchers, scientists, and regulators can understand the impact of human activities, seasonal fluctuations, and weather events. Water quality data helps inform sustainable decision making and comprehensive regulatory policy. Environmental water quality refers to the chemical, biological, and physical properties of water. Parameters such as pH, conductivity (or salinity), and dissolved oxygen can be measured to characterize the chemical qualities of sample water. Sampling, continuous monitoring, and remote monitoring are all used to collect water quality data. Environmental monitoring programs are typically specified and or managed by water resource control agencies at a local, state, and national level.

Environmental Monitoring Applications

Environmental water quality monitoring encompasses a variety of different applications, since there are many different ecosystems where water is a critical resource. Examples of environmental water quality monitoring applications include:

Surface water

Monitoring surface water helps assess the health of rivers, lakes, and reservoirs, ensuring they meet safety standards for human use and aquatic life.

Groundwater

Groundwater monitoring tracks the quality of water stored beneath the Earth’s surface, essential for maintaining drinking water supplies and agricultural use.

Stormwater

Stormwater monitoring is used to evaluate runoff water, ensuring pollutants from urban and industrial areas are managed effectively before reaching water bodies.

Ballast water

Ballast water monitoring is critical to prevent the spread of invasive species and protect marine ecosystems from unintended introductions.

Ocean acidification

Monitoring ocean acidification helps track the decrease in pH levels of seawater, which can have significant impacts on marine life and ecosystems.

Identification of ocean hypoxic zones

Identifying hypoxic zones helps detect areas of low oxygen in oceans, which can lead to dead zones and disrupt marine biodiversity.

Estuarine and coastal ecosystems

Monitoring estuaries and coastal ecosystems is vital for understanding nutrient levels, pollution impacts, and biodiversity in these highly productive habitats.

Environmental testing or research laboratories

Research laboratories conduct water quality testing to provide accurate data for environmental studies and regulatory compliance.

Environmental Water Quality Sensors

Sensorex specializes in the design and manufacture of water quality sensors, including many of the electrochemical sensors used in environmental monitoring applications. Our OEM partners use our sensors in turnkey environmental monitoring systems, such as integrated observation platforms, environmental monitoring buoys, and multiparameter sondes.

pH and ORP Sensors

Our laboratory style pH and oxidation reduction potential (ORP) sensors are frequently used as part of multiparameter sondes for environmental monitoring applications. With standard 12mm x 150mm polymer bodies, these durable sensors can easily fit into a titanium sonde housing or observation platform manifold.

Conductivity / Salinity Sensors

Conductivity is a measure of the number of ions in solution and is frequently monitored in environmental applications. In some cases, conductivity measurements can be converted to salinity. Sensorex offers contacting conductivity sensors for freshwater applications as well as toroidal conductivity sensors for applications with high ion concentration, like ocean monitoring.

Custom Environmental Water Quality Monitoring Sensors

Our expertise in the development of custom pH, ORP, conductivity, and dissolved oxygen sensors has made Sensorex a trusted design partner for leading environmental water quality companies.
