When it comes to pollution sources, their distribution and the diffusion of pollutants in groundwater are important factors for Director Gong to set up wastewater monitoring points. Based on the local underground flow direction and the distribution of pollution sources, the wastewater monitoring points can be set up through the method of sampling point arrangement. This requires considering multiple aspects. In this article, we will conduct a simple analysis on the setting of Groundwater Monitoring points.

Regarding Industrial Pollution Sources

For example, industrial clusters:

① Set one monitoring point, and place it at the upstream boundary of the underground water flow in the industrial cluster;

② Set 5 monitoring points for pollution diffusion monitoring points, arranged vertically along the underground water flow direction in a fan-shaped pattern, with no less than 3 points in each section; set one point on both sides of the industrial cluster along the underground water flow direction;

③ It is an internal monitoring point within the industrial cluster, requiring 3 to 5 points; however, each point needs to be set according to the area, with at least 1 additional point added for every 15 square kilometers of the monitoring area, and also set 3 points in the industrial cluster area.

Setting monitoring points for some industrial enterprises outside the industrial cluster:

① This is the same as point ①;

② The pollution diffusion monitoring points are different from the above; here, no less than 3 points are required, while the monitoring points on the downstream and both sides of the underground water cannot be less than one each;

③ The internal monitoring points for industrial enterprises require 1 to 2 more points; it is also set according to the area, the same as point ③; in addition, there may be areas with groundwater pollution risks in the monitoring points.

Understanding the Setting of Some Groundwater Monitoring Points for gas Stations

1) After you understand the underground water flow direction, the pollution diffusion monitoring point mainly requires 1 point, set at the downstream of the underground water, 5 to 30 meters away from the buried oil tank;

2) If the underground water flow direction is unclear, set 3 monitoring points, distributed in a triangular shape, with the same distance as point 1);

3) For industrial wastewater monitoring, agricultural wastewater monitoring, and medical wastewater online monitoring, ensure the safe discharge of these wastewater, so that the safety of groundwater will be further guaranteed!
