Sampling Equipment<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Selecting groundwater sampling equipment only by price or maximum depth can result in an unsuitable field configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before purchasing equipment, evaluate the following factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Monitoring-Well Depth<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Provide both the total well depth and the actual static water level.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These two numbers are not necessarily the same.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The pump must be able to operate at the required sampling depth under actual field conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI currently publishes a standard 70 m lift for AML918 and a standard 70 m sampling depth for AML919. Deeper applications should be technically confirmed according to the specific configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Well Diameter<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The pump and sampling assembly must fit inside the monitoring well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Provide:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Well diameter<\/li>\n\n\n\n<li>Casing diameter<\/li>\n\n\n\n<li>Screen interval<\/li>\n\n\n\n<li>Total depth<\/li>\n\n\n\n<li>Sampling depth<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">before selecting the equipment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Static Water Level<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Static water level affects the actual pumping lift.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not select a pump based only on total well depth.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Required Flow Rate<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Different procedures require different flow conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">High-flow operation may be required for well purging or well washing, while controlled lower-flow operation may be used during sampling.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5. Target Contaminants<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The target contaminant affects sampling requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For VOC projects, the sampling method should consider volatilization, air exposure and sample handling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For other contaminants, different materials and sampling configurations may be appropriate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Sampling Method<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Confirm whether your project requires:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Low-flow sampling<\/li>\n\n\n\n<li>Bladder-pump sampling<\/li>\n\n\n\n<li>Conventional pump sampling<\/li>\n\n\n\n<li>Well purging<\/li>\n\n\n\n<li>Well development<\/li>\n\n\n\n<li>Grab sampling<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">7. Equipment Materials<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For difficult groundwater conditions, pump-body and tubing materials should be evaluated for chemical compatibility and corrosion resistance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The AML919, for example, uses a 316 stainless-steel pump body and PTFE sampling tubing according to AIMOLI&#8217;s current published information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">8. Decontamination and Cross-Contamination Control<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Equipment selection should be accompanied by a suitable decontamination procedure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sampling teams should consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pump body<\/li>\n\n\n\n<li>Tubing<\/li>\n\n\n\n<li>Connectors<\/li>\n\n\n\n<li>Sampling

has published a case involving a groundwater well deeper than 300 meters at the Fourth Academy of Nuclear Science and Technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the company&#8217;s published case description, the application involved technical evaluation of groundwater sampling equipment for a deep well where conventional manual sampling was not considered suitable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This case demonstrates why total well depth alone is not sufficient when selecting sampling equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The actual water level, sampling depth, required flow and pump configuration must also be considered.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Groundwater Monitoring Equipment Training Application<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI has also published information about groundwater monitoring equipment used in training associated with the Inner Mongolia Environmental Monitoring Center.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The equipment listed in the application includes AML918D, AML918, AML919 and AML916, covering groundwater well development, groundwater sampling, bladder-pump sampling and field groundwater measurement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This type of multi-equipment workflow demonstrates how groundwater sampling can be integrated with measurement and well-purging procedures.<\/p>\n\n\n\n<figure

FAQ<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">What is groundwater sampling equipment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater sampling equipment is a group of pumps, samplers, tubing, controllers and related instruments used to collect groundwater samples from monitoring wells or other groundwater locations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What equipment is used for groundwater sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Common equipment includes groundwater sampling pumps, bladder pumps, low-flow sampling systems, bailers, tubing, controllers and field water-quality instruments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correct combination depends on the sampling procedure and well conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a groundwater sampling pump?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A groundwater sampling pump is used to move groundwater from a monitoring well to the sampling point under controlled operating conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Different pumps provide different flow ranges, lift capabilities and sampling methods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a groundwater bladder pump?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A groundwater bladder pump uses a flexible bladder and pressure-driven pumping principle to move groundwater through sampling tubing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is commonly considered for controlled and low-flow groundwater sampling.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is low-flow groundwater sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Low-flow groundwater sampling is a controlled sampling approach intended to reduce unnecessary disturbance to the monitoring well and support representative sample collection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact operating procedure should follow the applicable project method or regulatory requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What equipment is suitable for groundwater VOC sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Equipment selection for VOC sampling should consider sampling method, flow control, sample exposure to air, tubing materials, well depth and sample-handling requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI positions the AML919 groundwater sampler for VOC collection and low-flow groundwater sampling.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can groundwater sampling equipment be used in deep wells?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, but the equipment must be selected according to actual water level, required sampling depth, well construction and pump lift.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI currently publishes a standard 70 m lift for AML918 and a standard 70 m sampling depth for AML919, while deeper applications require configuration confirmation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do I select groundwater sampling equipment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Provide the supplier with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Well diameter<\/li>\n\n\n\n<li>Total well depth<\/li>\n\n\n\n<li>Static water level<\/li>\n\n\n\n<li>Required sampling depth<\/li>\n\n\n\n<li>Required flow rate<\/li>\n\n\n\n<li>Sampling method<\/li>\n\n\n\n<li>Target contaminants<\/li>\n\n\n\n<li>Number of monitoring wells<\/li>\n\n\n\n<li>Well-purging requirements<\/li>\n\n\n\n<li>Project location<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The supplier can then evaluate the appropriate pump, sampler and system configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is the difference between a groundwater sampling pump and a bladder pump?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A groundwater sampling pump and bladder pump use different pumping principles and may be suited to different sampling requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A conventional groundwater sampling pump may provide wider flow capability and can be useful when both well purging and sampling are required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A bladder pump is commonly considered when controlled low-flow sampling is the primary requirement.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Request Groundwater Sampling Equipment<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing groundwater sampling equipment without knowing the well conditions can result in an unsuitable configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Send AIMOLI the following information:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Well information<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Well
