How to Measure Groundwater Flow Velocity and Direction in a 1,500 m Geothermal Deep Well? A Real Customization Case For conventional groundwater monitoring wells, measuring groundwater flow velocity and direction is not particularly difficult. However, when the well depth reaches 1,500 meters and the well is located in a geothermal environment, the situation becomes completely…

How to Choose a Groundwater Three-Water-Level Meter? Understanding the AML913 Integrated Measurement Solution from the Perspective of Data Consistency in Multi-Well Operations For third-party groundwater monitoring service providers, selecting field equipment is not simply a matter of comparing price and measurement accuracy. What truly affects the efficiency of multi-well operations is often a seemingly simple…

Q: Is well purging mandatory for field sampling? A: Yes. HJ 1019—2019 requires purging the well until water quality parameters stabilize or a specified volume of water is removed; additionally, disturbances such as air-lifting or aeration within the well must be avoided. Q: Should bailers be phased out? A: No. Standards still retain the bailer…

Abstract:Last week, Mr. Chen, an engineer from an environmental monitoring station in Henan, contacted us for an equipment demonstration. The well was located in Hebei, while Mr. Chen was in Henan. Our engineer operated the equipment on site and recorded downhole footage with depth markers, then sent the video to Mr. Chen for remote well-condition…

Frequent Signal Loss at Over 200 Meters? How the Inspection of More Than 40 Wells Was Completed About 3 months ago, Mr. Liu, the general manager of a third-party company in Northwest China, contacted us. They were preparing to undertake a well condition inspection project involving more than 40 wells, with well depths ranging from…

One Graduate Student Could Only Run Two Samples in an Afternoon: The Bottleneck in Microplastic Detection Was Not “Accuracy,” but “Can We Actually Process Enough Samples?” This is a delivery case from a microplastic laboratory at a university in East China. Before the system was introduced, the laboratory’s normal workflow was that one graduate student…

A groundwater bladder pump is a type of groundwater sampling equipment designed for controlled groundwater sampling, particularly low-flow and VOC sampling applications. Unlike a conventional submersible pump, a bladder pump uses a flexible bladder to separate the drive air from the groundwater sample. This operating principle can help reduce direct contact between drive air and…
