How do you choose a groundwater sampling pump suitable for deep wells and VOC sampling?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When conducting groundwater environmental monitoring in complex environments such as mountainous areas and the field, sampling personnel often face problems such as heavy equipment, difficult transportation, insufficient lift for deep wells, slow water discharge, as well as volatilization losses and cross-interference during VOC sampling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To address these application needs, the <strong>AIMOLI 919 <a href=\"https:\/\/www.aimoli2016.cn\/?p=327\" title=\"\">Bladder Pump<\/a> Groundwater Sampler (AML919)<\/strong> is specifically designed for groundwater environmental monitoring, deep-well groundwater sampling, and groundwater VOC sampling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The equipment features a 316 stainless steel body, with an overall weight approximately 40% lower than traditional equipment. It has a standard lift of 70 meters and uses quick-connect interfaces, helping improve the efficiency of on-site groundwater sampling in mountainous areas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following actual project case from a municipal environmental monitoring center in Yunnan demonstrates how AIMOLI 919 solves practical challenges in deep-well <a href=\"https:\/\/www.aimoli2016.cn\/\" title=\"\">groundwater sampling<\/a> in mountainous areas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Why Is Groundwater Sampling in Mountainous Areas and Deep Wells Difficult?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Last month, we received a request for assistance from Mr. Zhang, a teacher at a municipal environmental monitoring center in Yunnan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mr. Zhang was responsible for a groundwater environmental monitoring project in a mountainous area. Because the sampling locations were located in mountainous terrain, some monitoring wells were relatively deep. At the same time, the project involved <strong>VOCs (volatile organic compounds) testing<\/strong>, which placed higher requirements on the groundwater sampling equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the traditional groundwater sampling equipment was difficult to adapt to the site conditions, the project had already fallen three days behind schedule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After analyzing the site conditions, the main problems were concentrated in two areas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Heavy equipment made transportation difficult in mountainous field environments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater sampling in mountainous areas often requires personnel to walk into sampling areas, and some monitoring points cannot even be reached directly by vehicles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional groundwater sampling equipment and supporting systems are relatively heavy, and transferring the equipment usually requires cooperation between multiple people. This not only increases the burden of transporting the equipment but also extends the on-site operation time for each monitoring well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For projects requiring continuous sampling of multiple monitoring wells, <strong>the portability of groundwater sampling equipment directly affects overall sampling efficiency.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, groundwater sampling equipment for mountainous areas needs to consider not only sampling performance but also:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Equipment weight<\/li>\n\n\n\n<li>Portability<\/li>\n\n\n\n<li>On-site installation speed<\/li>\n\n\n\n<li>Pipeline connection efficiency<\/li>\n\n\n\n<li>Single-person operation<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Insufficient lift made traditional bladder pumps unsuitable for deep wells<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some areas of the project involved deep wells, while VOC testing was also required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compared with ordinary groundwater sampling, groundwater VOC sampling places higher requirements on controlling sample disturbance, volatilization losses, and cross-interference. Therefore, an appropriate groundwater bladder pump needs to be selected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common problems with traditional groundwater bladder pumps in actual applications include <strong>slow water discharge and limited lift.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the monitoring well becomes deeper, insufficient lift from the groundwater sampling pump may result in difficulty discharging water and excessive sampling time, thereby affecting on-site work efficiency and project progress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, for deep-well groundwater sampling in mountainous areas, the following factors need to be considered when selecting groundwater sampling equipment:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Portability, lift, continuous and stable water discharge capability, and suitability for VOC sampling.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">2. What Are the Advantages of the AIMOLI 919 Bladder Pump Groundwater Sampler?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Designed for mountainous field environments, deep wells, and <a href=\"https:\/\/www.aimoli2016.cn\/?p=54\" title=\"\">groundwater VOC sampling<\/a>, the AIMOLI 919 Bladder Pump Groundwater Sampler focuses on solving the problems of traditional groundwater bladder pumps in terms of portability, lift, and sampling efficiency.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. 316 Stainless Steel Body and Portable Design for Groundwater Sampling in Mountainous Areas<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The AIMOLI 919 features a <strong>316 stainless steel body<\/strong>, with an overall weight approximately 40% lower than traditional equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A single operator can carry the equipment between different monitoring wells, reducing the burden of equipment transportation during groundwater sampling in mountainous areas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the same time, AML919 uses quick-connect interfaces, which can reduce on-site equipment installation and pipeline connection time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to actual applications, the equipment can discharge water in approximately 3 minutes on average, meeting the efficiency requirements of field groundwater sampling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For groundwater sampling projects in mountainous areas, forested areas, and other locations with difficult transportation, portable groundwater sampling equipment can effectively reduce the difficulty of on-site operation and equipment transportation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. 70-Meter Standard Lift for Deep-Well Groundwater Sampling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For deep-well groundwater sampling, <strong>lift is one of the important technical indicators when selecting a groundwater sampling pump.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The AIMOLI 919 Bladder Pump Groundwater Sampler has a standard lift of <strong>70 meters<\/strong>, which can meet the requirements of most deep-well groundwater sampling applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In actual applications, users have also used AML919 for groundwater sampling in monitoring wells with depths of <strong>300 meters<\/strong>, with stable continuous operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, AML919 is suitable not only for ordinary groundwater monitoring wells but can also be applied to groundwater sampling projects involving deeper monitoring wells.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Key Features of the AIMOLI 919 Bladder Pump<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The sampling method of a bladder pump + the water discharge efficiency of a submersible pump.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The equipment can provide continuous and stable water discharge, improving on-site sampling efficiency while meeting groundwater sampling requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For deep-well groundwater sampling projects, the equipment needs not only to be capable of collecting samples but also to minimize the operating time for each monitoring well while meeting project sampling requirements.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">3. Is AIMOLI 919 Suitable for Groundwater VOC Sampling?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If a groundwater environmental monitoring project involves VOC (volatile organic compounds) testing, the selection of sampling equipment needs to focus on sample disturbance, volatilization losses, and cross-interference during the sampling process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The AIMOLI 919 Bladder Pump Groundwater Sampler is suitable for groundwater environmental monitoring and related VOC sampling applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its sampling method can be used to reduce sample disturbance that may occur with traditional sampling methods, helping meet the sample integrity requirements of groundwater VOC sampling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The product design and application of AML919 can be combined with the following technical specifications related to groundwater environmental monitoring:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>HJ 164-2020 &#8220;Technical Specification for Groundwater Environmental Monitoring&#8221;<\/strong><\/li>\n\n\n\n<li><strong>HJ 1019-2019 &#8220;Technical Guidelines for Sampling of Volatile Organic Compounds in Soil and Groundwater at Contaminated Sites&#8221;<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Currently, relevant departments in <strong>28 provinces and municipalities across China use AML919 as an enforcement instrument.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In actual project applications, AML919 has also been involved in multiple groundwater environmental monitoring projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Note: Whether a specific project meets regulatory, acceptance, or testing requirements should be confirmed according to the project type, testing indicators, local management requirements, and applicable technical specifications.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">4. Yunnan Mountainous Groundwater Sampling Case: How Did AIMOLI 919 Help the Project Recover Its Schedule?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">When Mr. Zhang contacted us, the project was already three days behind the original schedule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the original groundwater sampling equipment had continued to be used, the subsequent sampling work would likely have been further delayed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After understanding the site conditions, we developed a corresponding groundwater sampling solution based on the monitoring well depths, sampling indicators, and site environment, and arranged for engineers to bring the relevant equipment to Yunnan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The entire project was not completed by relying on a single piece of equipment. Instead, the <strong>coordination of water-level measurement, well purging, and groundwater sampling equipment<\/strong> was used to optimize the overall groundwater sampling process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: AIMOLI 913 Groundwater Three-Parameter Water Level Meter<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">First, the AIMOLI 913 Groundwater Three-Parameter <a href=\"https:\/\/www.aimoli2016.cn\/?p=67\" title=\"\">Water Level Meter<\/a> was used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Through equipment integration, a single deployment into the well can obtain:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Groundwater level<\/li>\n\n\n\n<li>Well depth<\/li>\n\n\n\n<li>Drawdown<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This reduces repeated measurements and improves the efficiency of on-site monitoring well measurements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Linkage Between AIMOLI 913 and AIMOLI 918D Well Purging Pump<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After completing the well condition measurements, the AIMOLI 913 was combined with the AIMOLI 918D Well Purging Pump to achieve linked control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Through coordination between the equipment, repeated operations before groundwater sampling can be reduced, shortening the time required for well purging and sampling preparation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For projects requiring continuous sampling of multiple monitoring wells, a systematic sampling workflow can further improve on-site work efficiency.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: AIMOLI 919 for Groundwater Sampling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After completing the preliminary preparations, the engineers used the <strong>AIMOLI 919 Bladder Pump Groundwater Sampler<\/strong> to collect groundwater samples.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With its portable design, 70-meter standard lift, and stable water discharge capability, AML919 helped the field engineers improve deep-well groundwater sampling efficiency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, the project managed by Mr. Zhang <strong>completed the sampling and testing work within the original schedule, and the sampling data passed the acceptance process on the first attempt.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">5. How Do You Choose a Groundwater Sampling Pump for Mountainous Areas and Deep Wells?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If your groundwater environmental monitoring project involves mountainous areas, deep wells, or groundwater VOC sampling, the following factors can be considered when selecting a groundwater sampling pump.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Groundwater Sampling in Mountainous Field Environments<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Key considerations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Equipment weight<\/li>\n\n\n\n<li>Portability<\/li>\n\n\n\n<li>Single-person operation<\/li>\n\n\n\n<li>Quick installation<\/li>\n\n\n\n<li>Adaptability to field environments<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Deep-Well Groundwater Sampling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Key considerations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Maximum lift<\/li>\n\n\n\n<li>Water discharge speed<\/li>\n\n\n\n<li>Continuous water discharge capability<\/li>\n\n\n\n<li>Actual deep-well application cases<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Groundwater VOC Sampling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Key considerations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sampling method<\/li>\n\n\n\n<li>Sample disturbance<\/li>\n\n\n\n<li>Control of volatilization losses<\/li>\n\n\n\n<li>Control of cross-interference<\/li>\n\n\n\n<li>Applicable technical specifications<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Environmental Monitoring Projects<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to the performance of a single groundwater sampling pump, attention should also be given to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Groundwater level measurement<\/li>\n\n\n\n<li>Monitoring well depth measurement<\/li>\n\n\n\n<li>Well purging<\/li>\n\n\n\n<li>Groundwater sampling<\/li>\n\n\n\n<li>On-site data recording<\/li>\n\n\n\n<li>Coordinated operation between different pieces of equipment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">And whether these capabilities can form a complete groundwater environmental monitoring solution.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">6.

Frequently Asked Questions: Groundwater Samplers and Bladder Pumps<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">1. What is a groundwater bladder pump?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A groundwater bladder pump is a sampling device used to collect groundwater samples. It uses gas to drive a bladder, allowing groundwater to enter the sampling line and be transported to the surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compared with some traditional groundwater sampling methods, a bladder pump can reduce disturbance to groundwater samples during the sampling process and is therefore commonly used in groundwater environmental monitoring and related VOC sampling applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. What lift should a groundwater sampling pump have for deep-well sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It should be determined based on the actual monitoring well depth, groundwater level, sampling position, and site operating conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For deep-well groundwater sampling, the actual lift capability of the groundwater sampling pump should be verified rather than relying only on theoretical equipment specifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The standard lift of AML919 is 70 meters, and there is an actual application case involving a 300-meter-deep monitoring well.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Can AIMOLI 919 be used for groundwater VOC sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, it can be used for related groundwater VOC sampling applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">VOC sampling has high requirements for controlling sample disturbance and volatilization losses. Specific sampling methods and operating procedures should be implemented according to project requirements and relevant technical specifications such as HJ 1019-2019.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Is AIMOLI 919 suitable for groundwater sampling in mountainous areas?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 features a portable design and 316 stainless steel body, with an overall weight approximately 40% lower than traditional equipment. It also uses quick-connect interfaces, making it suitable for groundwater sampling in mountainous areas, field environments, and locations with difficult transportation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5. What is the standard lift of AIMOLI 919?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The standard lift of AML919 is <strong>70 meters<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In actual applications, users have used it in monitoring wells with depths of up to 300 meters. The specific equipment configuration and applicable depth should be confirmed based on the monitoring well structure, groundwater level, and site operating conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Why is well purging required before groundwater sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the main purposes of well purging is to remove water inside the monitoring well that may have been affected by construction, sediment, or long-term storage, so that the collected groundwater samples can better represent the actual water quality of the target aquifer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The specific well-purging method and termination conditions should be implemented according to the relevant technical specifications adopted for the project.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">9. Why Are More Environmental Monitoring Projects Paying Attention to the Overall Efficiency of Groundwater Sampling Equipment?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater environmental monitoring is not simply about &#8220;pumping water out.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A complete groundwater sampling project usually involves:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Monitoring well measurement \u2192 Well purging \u2192 Groundwater sampling \u2192 Sample preservation \u2192 Laboratory testing.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If any step has low efficiency, it may affect the progress of the entire project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, in mountainous areas, deep-well projects, and large-scale groundwater environmental monitoring projects, instead of focusing only on a single piece of equipment, it is more effective to select groundwater environmental monitoring equipment based on the complete sampling workflow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI provides an equipment combination of <strong>913 Groundwater Three-Parameter Water Level Meter + 918D Well Purging Pump + 919 Bladder Pump Groundwater Sampler<\/strong>, which can provide an equipment combination solution for monitoring well measurement, well purging, and groundwater sampling.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">10. Solving Deep-Well Groundwater Sampling Challenges Starts with Choosing the Right Sampling Equipment<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The real difficulty of groundwater sampling in mountainous areas is not simply &#8220;getting the water out.&#8221; It requires simultaneously balancing <strong>equipment portability, lift, sampling efficiency, and sample quality<\/strong> under complex field conditions, deep-well conditions, and standardized sampling requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The AIMOLI 919 Bladder Pump Groundwater Sampler is optimized to address problems such as <strong>difficult transportation, insufficient lift, and low water discharge efficiency<\/strong> associated with traditional groundwater bladder pumps, providing an efficient groundwater sampling solution for mountainous areas, deep wells, and groundwater VOC sampling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your project involves <strong>deep wells, mountainous areas, difficult field equipment transportation, insufficient lift from traditional bladder pumps, or low groundwater sampling efficiency<\/strong>, you can further evaluate the equipment configuration, technical specifications, and actual application cases of AML919.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AIMOLI 919 Bladder Pump Groundwater Sampler makes deep-well groundwater sampling simpler and more efficient.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AIMOLI Environmental Instruments \u2014 Specialized in groundwater environmental monitoring and sampling equipment, providing professional groundwater sampling solutions for environmental monitoring projects.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AIMOLI Environmental Instruments \u2014 Precise enough to make our peers anxious!<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"1024\" src=\"http:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-576x1024.png\" alt=\"\" class=\"wp-image-185\" srcset=\"https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-576x1024.png 576w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-169x300.png 169w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-768x1365.png 768w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-864x1536.png 864w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25.png 941w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>AIMOLI 919 Bladder Pump Groundwater Sampler: Solving Groundwater Sampling Challenges in Mountainous Areas and Deep Wells Why is groundwater sampling in mountainous areas and deep wells difficult?
