Following discussions, product presentations, and an on-site equipment inspection, the client approved the proposed equipment configuration from AIMOLI. The two parties signed the purchase contract on the third day of the National Day holiday and coordinated equipment dispatch on the fourth day, helping the client make progress toward the project’s subsequent implementation.<\/p>\n\n\n\n
1. Project Background: Groundwater Purging and Sampling Across 20 Wells Required Higher Equipment Standards<\/h2>\n\n\n\n
The third-party testing center where Mr. Ma works had undertaken a groundwater well purging and sampling project involving 20 wells. According to the project requirements, the equipment needed not only to meet the relevant national and industry technical specifications but also to support well purging, sampling, and on-site monitoring. It also needed to support the required data traceability and operation records.<\/p>\n\n\n\n
As the project was commissioned by a government entity, standardized fieldwork and process management were particularly important. How to improve on-site work efficiency and standardize well purging and sampling procedures while maintaining sampling quality became a key consideration in the client’s equipment purchasing decision.<\/p>\n\n\n\n
2. What Problems Can Traditional Bailer Sampling Present?<\/h2>\n\n\n\n
According to Mr. Ma, the project team had previously relied primarily on traditional bailers for groundwater sampling, while well purging was often carried out using relatively simple methods. For a project involving 20 wells, this approach presented challenges in staffing, field operations, and sampling procedure standardization.<\/p>\n\n\n\n
1. Relatively Low Fieldwork Efficiency<\/h3>\n\n\n\n
Traditional bailer sampling typically requires workers to lower and retrieve the sampling tube repeatedly. Based on the client’s previous experience, routine field sampling required three to four workers to work together. This involved considerable personnel input and a relatively complicated workflow.<\/p>\n\n\n\n
2. Limited Water Volume per Sampling Cycle<\/h3>\n\n\n\n
Taking the 1,000 mL bailer previously used by the client as an example, the bailer fills with water when lowered into contact with the water body. A small amount of leakage may occur during retrieval, resulting in an actual water sample volume of approximately 700\u2013800 mL per sampling cycle.<\/p>\n\n\n\n
The actual sample volume may vary depending on the equipment specifications, operating method, and site conditions.<\/p>\n\n\n\n
3. Potential Limitations in Sample Representativeness<\/h3>\n\n\n\n
In certain applications, traditional bailer sampling may make it difficult to obtain water samples precisely from a target groundwater layer. For groundwater monitoring projects that focus on the water quality of a specific layer, equipment selection and sampling methods should be determined based on well construction, monitoring objectives, and applicable technical specifications.<\/p>\n\n\n\n
4. Considerable Workload for Well Purging<\/h3>\n\n\n\n
When traditional bailers are used for well purging, repeated lowering and retrieval operations can result in a substantial fieldwork burden. Without suitable equipment and standardized operating procedures, both work efficiency and process management for well purging and sampling may be affected.<\/p>\n\n\n\n
For third-party testing institutions handling multiple wells, stringent quality control requirements, and defined project schedules, selecting appropriate groundwater sampling equipment can help improve fieldwork procedures and enhance the standardization of project execution.<\/p>\n\n\n\n
3. AIMOLI’s Groundwater Sampling and Monitoring Equipment Solution<\/h2>\n\n\n\n
After learning about the client’s project requirements, AIMOLI’s staff communicated with Mr. Ma and invited him to inspect the equipment in person. As the client wanted to finalize the purchasing plan promptly, AIMOLI arranged a visit on the third day of the National Day holiday, providing equipment explanations and physical demonstrations tailored to the project.<\/p>\n\n\n\n
During the visit, the client focused on the following three products:<\/p>\n\n\n\n
1. AML 918 Groundwater Sampling Pump<\/h3>\n\n\n\n
The AML 918 Groundwater Sampling Pump<\/a> is primarily used for groundwater sampling operations. Equipment selection should be evaluated in accordance with sampling depth, well conditions, target water samples, and project technical requirements to ensure suitability for the specific field sampling task.<\/p>\n\n\n\n The AML 913 Groundwater Level Meter<\/a> is used to measure groundwater levels and can be used in groundwater monitoring activities. In practical applications, the appropriate configuration should be selected based on field measurement requirements and the equipment’s technical specifications.<\/p>\n\n\n\n The AML 916 Groundwater 6-Parameter Meter<\/a> is designed for on-site multi-parameter groundwater measurement and can provide relevant data support for field monitoring. The specific parameters measured, measurement ranges, and technical specifications should be confirmed against the official product documentation.<\/p>\n\n\n\n Through detailed explanations of equipment functions, applicable scenarios, and project configuration, the client gained a better understanding of how groundwater sampling equipment, groundwater level measurement instruments, and on-site multi-parameter monitoring instruments can work together.<\/p>\n\n\n\n2.
