Seawater Bathing Area Water Quality Monitoring Plan

As people’s living standards improve and urban leisure and vacation trends gain momentum, famous seaside bathing beaches often become overcrowded during the summer months. Currently, although some monitoring equipment is in place for seawater data and visitor surveillance at these beaches, the former requires manual deployment into the seawater for data collection, making it impossible to achieve real-time, automated data acquisition and alerting. As for the latter, it relies merely on simple video surveillance without any further processing of the video footage. Such monitoring systems thus have limited coverage and generally poor effectiveness. Therefore, there is an urgent need to establish an automated monitoring system for seaside bathing beaches, enabling timely tracking of water quality changes and providing the public with valuable public-service information.

As people’s living standards improve and urban leisure and vacation trends gain momentum, famous seaside bathing beaches often become overcrowded during the summer months. Currently, although some monitoring equipment is in place for seawater data and visitor surveillance at these beaches, the former requires manual deployment into the seawater for data collection, making it impossible to achieve real-time, automated data acquisition and alerting. As for the latter, it relies merely on simple video surveillance without any further processing of the video footage. Consequently, this type of monitoring system has limited coverage and generally unsatisfactory results. Therefore, there is an urgent need to establish an automated monitoring system for seaside bathing beaches, enabling timely detection of changes in water quality and providing the public with valuable public-service information.

It is necessary to strengthen environmental monitoring at bathing beaches and for relevant authorities to promptly release information on water quality conditions, thereby fulfilling the public’s right to know about environmental conditions. Precise monitoring of seawater bathing beach water quality will ensure high-quality water standards, providing citizens and tourists with reliable assurance of swimming water safety and promoting the development of coastal tourism and the marine economy.

Scheme Features

Based on the specific characteristics and requirements of seawater bathing beach water quality, Qingdao Jiaming has developed an automated seawater quality monitoring system by leveraging the Qingdao Municipal Special Fund for Marine Science and Technology Innovation and the National Scientific Research Special Fund. This system is a comprehensive, online automated monitoring platform that integrates modern sensor technology, automatic measurement technology, automatic control technology, computer application technology, as well as related quality-control techniques, specialized analytical software, and communication networks. The station buildings come in various designs, including shore-based stations, buoy stations, and pole-mounted stations, and are equipped with complete features such as water supply, power supply, lightning protection, grounding, sealing, thermal insulation, network communication, and video surveillance.

The system enables rapid monitoring of fecal coliforms, enterococci, and Staphylococcus aureus. It integrates various microbiological and physicochemical indicators for seawater bathing sites, providing a comprehensive instrument that measures both microbial and physicochemical parameters of seawater quality. Leveraging intelligent image recognition and big data technologies, the system builds a smart cloud platform, establishing an integrated system for seawater quality monitoring, early warning, and traceability.
