At a time when the world is paying more and more attention to environmental protection, the importance of water quality monitoring is self-evident. However, its development has encountered many bottlenecks. On the one hand, the uneven distribution of monitoring points and the insufficient number of monitoring points cannot fully and accurately reflect the water quality of the water area. Taking a large lake as an example, only a few monitoring points are set up sporadically around it, and the center of the lake and other areas have been in the monitoring blind spot for a long time. Once the water quality is abnormal, it is difficult to detect it in time. On the other hand, the aging of monitoring equipment and lagging technology have resulted in poor detection capabilities for trace pollutants and emerging pollutants. For example, some old sensors have extremely low detection sensitivity for some new pesticide residues, which cannot meet the increasingly stringent monitoring needs. At the same time, the massive monitoring data lacks unified standards and effective sharing mechanisms, forming "data islands" with low utilization rates. ​

In response to these thorny issues, industry experts and relevant departments have taken active actions. In order to optimize the layout of monitoring points, multiple departments such as water conservancy and environmental protection have jointly conducted research and scientifically planned additional monitoring points based on factors such as water functions and water flow directions. In terms of technological innovation, we will increase capital investment and encourage enterprises to develop new monitoring equipment, such as high-sensitivity sensors made of nanomaterials, which have greatly improved detection accuracy compared to traditional equipment. In terms of data management, we will start to build a national water quality monitoring data sharing platform to break down data barriers between departments and regions, promote data circulation, provide strong support for water quality management decisions, and help the water quality monitoring industry reach new heights.

Drinking water safety is clearly a critical priority.Yet the number of threats to water safety continues to grow daily, and include animal and human waste, improper disposal of chemicals, pesticides, and deep earth injection of hazardous materials. Contamination is also a threat due to improper water treatment and disinfection procedures, as well as from poorly maintained water distribution systems.

The Safe Drinking Water Act, has established national health-based standards that address both man-made and naturally occurring contamination. Compliance requires consistent, accurate measurement of water parameters performed in the lab, field, and online. While many measurements can be made in the lab, key variables such as pH, conductivity, fluoride, and chlorine can also be measured online in real-time to warn immediately if limits are exceeded.

Usually there is four steps for drinking water process
First step is Pre-treatment for source water
Second step is Filtration
Third step is disinfection process
Fourth step is distribution ,we have to measure pH,turbidity,hardness,residual chlorine,conductivity(TDS),then we can know the potential risks or threaten to public heath on time.the residual chlorine value should be over 0.3mg/L when be piped out from drinking water plant, and over 0.05mg/L at end of pipe network.turbidity must less 1NTU,pH value is between 6.5~8,5,pipe will be corrosive if pH value is less 6.5pH and easy scale if pH is over 8.5pH.

At present online water quality monitoring system can monitor water quality 24 hours and real time.it also provide quickly and correct information to decision-makers based on water quality changes in real time,Thereby providing people with healthy and safe water quality.
