Ground Water Quality Monitoring System

Ground water quality monitoring system is a facility designed for real-time monitoring of groundwater quality, typically deployed within pre-installed monitoring wells. Its primary function is to conduct continuous in-situ monitoring and data collection of groundwater level and quality parameters. This enables the timely tracking of changes in water level and quality, providing a scientific basis for the protection and management of groundwater resources.

I. Main Components

1. Sensor System：

Basic Parameter Sensors: water level, temperature, Atmospheric pressure, pH, conductivity, etc.

Inorganic parameters: Dissolved oxygen, ORP (Oxidation-Reduction Potential), turbidity, salinity, total dissolved solids (TDS), ammonia nitrogen, nitrate, chloride ions, etc.

Organic Matter Sensors: Chemical oxygen demand (COD), oil in water (OIW), etc.

2. Data Acquisition and Transmission System：

Data Logger: Responsible for collecting sensor data and performing preliminary processing.

Communication Module: Transmits data to the data center via wired or wireless methods (e.g., 4G, 5G).

3. Power Supply System：

Battery Power Supply: Typically equipped with high-capacity batteries to ensure long-term system operation and facilitate battery replacement.

Solar Power Supply:Usually includes solar panels, a power management unit, and batteries.

4. Data Processing and Storage System：

Local Storage: Used for temporary data storage to prevent data loss during network interruptions.

Remote Data Center: Used for long-term data storage and analysis.

II. Main Functions

1. Real-Time Monitoring:

Continuously monitors water quality parameters to promptly detect abnormal conditions.

2. Data Storage and Analysis:

Stores historical data for trend analysis and early warning.

3. Early Warning and Alarm:  

Automatically issues warnings or alerts when water quality parameters exceed preset thresholds.

Micro water quality monitoring stations play a crucial role in water environmental protection and resource management. Through real-time monitoring and data analysis, they effectively prevent and respond to water pollution incidents, ensuring the sustainable utilization of water resources.

III. Application

Groundwater Monitoring:  

Used to monitor the water level and quality of groundwater, assessing the health status of the water environment.

No need for land acquisition, simple structure and convenient installation.

2. Real-Time Capability:

Provides real-time water quality data, enabling rapid response.

3. Automation:

Reduces the need for manual intervention and lowers operational costs.

4. Multi-Functionality:

Can simultaneously monitor multiple water quality parameters, offering comprehensive water quality information.

5. Remote Management:

Enables remote monitoring and management via the internet, improving management efficiency.

V. Challenge

1. Equipment maintenance:

Senors require regular calibration and maintenance to ensure data accuracy.

2. Environmental adaptability:

Equipment needs to be able to adapt to a variety of harsh environmental conditions, such as high temperature, low temperature, humidity, etc.

3. Data security:

It is necessary to ensure the security of data transmission and storage to prevent data leakage or tampering.
