AIMOLI Groundwater Sampling Equipment for Accurate Groundwater Sampling and VOC Monitoring
Today, we received positive feedback from a new customer, Manager Lu. After using AIMOLI groundwater sampling equipment, he said the equipment made groundwater sampling much more convenient. The samples are reliable, the data is accurate, and the equipment significantly reduces the workload of field sampling personnel while reducing data errors caused by human operation.
For environmental companies working on groundwater pollution monitoring, chemical industrial park monitoring, site remediation, and VOC sampling, reliable groundwater sampling equipment is essential.
AIMOLI provides an integrated solution consisting of the AML913 Groundwater Three-Water-Level Meter and the AML919 Bladder Pump Groundwater Sampler. The system is designed to simplify groundwater well measurement, well purging, drawdown control, and groundwater sampling.
Traditional Groundwater Sampling: 3 Sets of Equipment and 3 Well Entries
Manager Lu is the person in charge of an environmental management company in southern China. His company mainly provides groundwater pollution monitoring and site remediation services for chemical industrial parks.
Before using AIMOLI groundwater sampling equipment, his company used traditional groundwater sampling equipment. Measuring water level, well depth, and drawdown required 3 sets of equipment and 3 separate well entries.
This traditional groundwater sampling process involves:
- 3 sets of equipment
- 3 separate well entries
- Repetitive measurement operations
- More field work
- Greater potential for human operating errors
According to the requirements of HJ1019-2019 and Huanban Tufang〔2017〕67, the drawdown depth during groundwater well purging should not exceed 10 cm.
After groundwater well purging meets the requirements, the water level should be measured and recorded.
If the groundwater level changes by less than 10 cm, groundwater sampling can be conducted immediately.
If the groundwater level changes by more than 10 cm, sampling should be conducted after the groundwater level becomes stable again.
If the groundwater recovery rate is relatively slow, in principle, groundwater sampling should be completed within 2 hours after well purging.
During this process, improper operation can cause sample errors or even make samples unusable. Manager Lu’s company had also experienced losses caused by these problems.
Three months ago, Manager Lu contacted AIMOLI to find a more convenient groundwater sampling solution.
AIMOLI AML913 + AML919 Groundwater Sampling Solution
Based on Manager Lu’s requirements, AIMOLI recommended two pieces of groundwater sampling equipment:
- AML913 Groundwater Three-Water-Level Meter
- AML919 Bladder Pump Groundwater Sampler
Together, these two instruments help simplify groundwater measurement, well purging, drawdown control, and groundwater sampling.
AML913 Groundwater Three-Water-Level Meter
The AML913 Groundwater Three-Water-Level Meter is designed to measure three important groundwater parameters with only one well entry.
1. Measure 3 Parameters with One Well Entry
The AML913 Groundwater Three-Water-Level Meter integrates a:
- Water level meter
- Well depth meter
- Drawdown meter
The instrument integrates more than 20 precision components into a probe about the size of a ham sausage.
With only one well entry, the AML913 can measure 3 parameters, significantly improving field work efficiency.
Traditional equipment requires 3 sets of instruments and 3 well entries, while the AML913 integrates these measurement functions into one system.
2. Automatic Drawdown Control
The AML913 Groundwater Three-Water-Level Meter can work together with the AML919 Bladder Pump Groundwater Sampler.
During groundwater well purging and groundwater sampling, the system can automatically control the drawdown range to no more than 10 cm.
This reduces human operating errors and helps maintain reliable groundwater samples.
For environmental companies conducting groundwater monitoring, this automatic drawdown control is particularly useful because groundwater level management is an important part of standardized groundwater sampling.
3. Stable Performance
The software of the three-water-level meter has been used for 10 years without any problems.
Under normal use, the probe is highly stable. Unless it is deliberately hit with a hammer or dropped from a five-story building, it is unlikely to malfunction during normal operation.
AML919 Bladder Pump Groundwater Sampler for VOC Sampling
For Manager Lu’s company, VOC sampling is particularly important in addition to conventional groundwater parameters.
The AML919 Bladder Pump Groundwater Sampler is designed for groundwater sampling applications where sample quality and reliable VOC collection are important.
1. Continuous Water Output
The AML919 bladder pump provides continuous water output.
It surpasses imported equipment and combines the sampling quality of a bladder pump with the efficiency of a submersible pump.
This makes the AML919 suitable for groundwater sampling projects that require efficient and reliable field sampling.
2. No Volatilization Loss and No Cross-Interference
The AML919 Bladder Pump Groundwater Sampler is designed so that throughout the entire sampling process there is:
- No volatilization loss
- No cross-interference
This feature makes the AML919 particularly suitable for VOC groundwater sampling.
For groundwater monitoring projects in chemical industrial parks, minimizing sample disturbance is especially important.
3. 70-Meter Standard Sampling Depth and 300-Meter Applications
The AML919 comes standard with a sampling depth of 70 meters.
There are also users operating the equipment at a depth of 300 meters, with no malfunctions.
This makes the AML919 applicable to different groundwater sampling depths and field monitoring conditions.

Frequently Asked Questions About Groundwater Sampling Equipment
Q1: Why is traditional groundwater sampling prone to errors?
Traditional groundwater sampling requires separate equipment and operations for water level, well depth, and drawdown. This means 3 sets of equipment and 3 well entries, resulting in repetitive operations and lower efficiency.
Samples can also develop errors or become unusable because of improper sampling operations.
The AML913 Groundwater Three-Water-Level Meter measures 3 parameters with one well entry, while the AML919 Bladder Pump Groundwater Sampler provides sampling with no volatilization loss and no cross-interference. Together, they reduce potential human errors through both equipment design and workflow.
Q2: How do the AML913 and AML919 work together?
The AML913 Groundwater Three-Water-Level Meter works together with the AML919 Bladder Pump Groundwater Sampler during groundwater well purging and sampling.
The system automatically controls the drawdown range to no more than 10 cm.
When the water level drawdown exceeds 10 cm, the equipment automatically pauses well purging. After the groundwater level naturally recovers, the operation restarts.
No manual operation is required throughout the process.
This operation complies with the requirements of HJ1019-2019 and Huanban Tufang〔2017〕67.
Q3: Why is the AML919 suitable for VOC groundwater sampling?
The AML919 Bladder Pump Groundwater Sampler uses a fully enclosed bladder design.
During the entire sampling process, the water sample does not come into contact with air. Therefore, there is no volatilization loss and no cross-interference.
The bladder pump provides continuous water output and combines the sampling quality of a bladder pump with the efficiency of a submersible pump.
The standard sampling depth is 70 meters, while users are operating the equipment at 300 meters without malfunctions.
Therefore, the AML919 is particularly suitable for VOC groundwater sampling in chemical industrial parks and other groundwater monitoring applications.
Q4: Is the AML913 Three-Water-Level Meter stable?
The AML913 three-water-level meter software has been used for 10 years without any problems.
Under normal operating conditions, the probe has high stability. Unless it is deliberately hit with a hammer or dropped from a five-story building, it is basically unlikely to malfunction.
Q5: Is the data from AIMOLI groundwater sampling equipment recognized?
AIMOLI groundwater sampling equipment is used as law-enforcement instruments by the National Analysis and Testing Center of the Ministry of Ecology and Environment and relevant departments in 28 provinces and cities.
