Application introduction related to water quality monitoring
Application of water quality monitoring in the field
Since water quality in rivers and lakes is critical to human and economic growth, proper assessment and estimation of water quality levels is essential. Water quality assessment is the cornerstone of environmental protection and an important part of water environment monitoring and management. It refers to the assessment of water quality using chemical, physical and biological parameters based on WQM data according to specific assessment criteria and procedures.
Qualitative and quantitative evaluation of water quality factors is required to effectively reflect the current status of water quality, aiming to understand the degree of influence and development trend of water pollution in design, and to provide scientific basis for protecting the water environment. Resource planning management. The choice of assessment techniques is at the heart of water quality assessment. The reliability of water quality assessment results is determined by the logic of the assessment procedure.
Several different water quality monitoring methods
CDOM/FDOM Monitoring: Colored or colored dissolved organic matter (CDOM) occurs naturally in waterways. This organic material absorbs UV light and breaks down, releasing tannins, an organic pollutant that causes cloudy water. Additionally, tannins cause the water's pH (acidity) to drop and deplete it of oxygen.
Chlorophyll Fluorescence Analysis: The proportion of wet chemical chlorophyll, as well as the active chlorophyll in the water samples, was measured with an algal toxicometer. This is a practical way to identify algae overgrowth and monitor water quality.
Conductivity, salinity and TDS monitoring: The conductivity of a river or lake is a good indicator of its quality. The total dissolved solids (TDS) content and the salinity of the water are affected by the conductivity, which in turn affects the oxygen content in the water.
Purpose of water quality monitoring
Water quality monitoring can be done for a variety of reasons. Characterize watersheds and determine trends and changes in water quality over time. It can detect specific current or potential water quality problems and collect data to develop pollution prevention or treatment plans. It can assess whether project objectives such as compliance with pollution legislation and enforcement of effective pollution prevention are being achieved. Water monitoring enables early detection of things like spills and floods.
Why Water Quality Monitoring Is Important
Monitoring provides the objective data needed to make informed choices about current and future water quality management. Water quality monitoring is used to detect current, ongoing and developing problems, as well as to assess compliance with drinking water regulations and protect other water-related activities.
Assessments based on monitoring data help lawmakers and water managers determine the effectiveness of water regulations, determine whether water quality is improving or deteriorating, and develop new policies to better protect human and environmental health. This is critical because climate patterns are changing and will continue to change, and rising water temperatures will lead to eutrophication and algal overgrowth, reducing drinking water quality.
The Hydrological monitoring station is suitable for remote monitoring of real-time water and rain conditions of rivers and reservoirs. Through the hydrological monitoring system, the management department can timely grasp the hydrological conditions of rivers, such as precipitation and section water level, so as to make management decisions in time. Hydrological monitoring station and early warning system plays an important role in timely warning flood disaster and avoiding human and economic losses.
The Future of Water Quality Monitoring
Advanced water quality monitoring methods and technological innovations, such as remote sensing, satellite imagery, earth observation, and smart sensors, will help generate reliable, continuous, and comprehensive water quality data scales over wide spatial and temporal scales. Additionally, anyone can participate in water quality monitoring using a variety of community science techniques.
