Without reliable groundwater flow data, it can be difficult to identify the potential migration path of pollutants, determine the pollution source, or develop an effective groundwater remediation strategy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a groundwater pollution investigation project conducted by a <strong>Hydrology and Geological Survey Brigade in Jiangsu Province, China<\/strong>, the investigation team encountered several challenges when measuring groundwater flow in a complex geological environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI provided the <strong>AML920 Groundwater Flow Velocity and Direction Instrument<\/strong> as the technical solution for groundwater flow measurement and field investigation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following case study explains the problems encountered, the measurement approach, the technical solution and the capabilities of the AML920.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Project Background<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater pollution investigations often require more than simply testing groundwater quality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When pollutants are detected in groundwater, investigators also need to understand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Where does the groundwater come from?<\/li>\n\n\n\n<li>In which direction does groundwater flow?<\/li>\n\n\n\n<li>How fast does groundwater move?<\/li>\n\n\n\n<li>How could pollutants migrate through the aquifer?<\/li>\n\n\n\n<li>Where is the potential pollution source?<\/li>\n\n\n\n<li>Which monitoring wells are located upstream and downstream?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow velocity and direction are therefore important parameters for <strong>groundwater pollution source tracing and environmental site investigation<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this Jiangsu project, the investigation team needed to determine groundwater flow conditions across a complex groundwater environment and obtain reliable field measurement data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, three major problems affected the investigation process.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Three Problems Encountered During Groundwater Pollution Investigation<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Problem 1: Difficulty Measuring Groundwater Flow Velocity Accurately<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater generally moves much more slowly than surface water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conventional flow measurement methods can therefore become difficult to apply when the groundwater velocity is very low.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Small measurement errors can result in significant differences in the calculated groundwater flow velocity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For groundwater pollution investigation, this can affect the interpretation of pollutant migration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The investigation team therefore required an instrument capable of measuring <strong>low groundwater flow velocities with high sensitivity and accuracy<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Problem 2: Difficulty Determining Groundwater Flow Direction<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing the groundwater flow velocity alone is not enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Investigators also need to determine the direction in which groundwater is moving.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow direction is particularly important when determining:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Potential pollutant migration pathways<\/li>\n\n\n\n<li>Upgradient and downgradient monitoring locations<\/li>\n\n\n\n<li>Possible pollution sources<\/li>\n\n\n\n<li>Groundwater remediation areas<\/li>\n\n\n\n<li>Monitoring well locations<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In complex geological conditions, groundwater flow direction may vary between different aquifers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The investigation team therefore required a method capable of measuring groundwater flow direction directly in the field.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Problem 3: Complex Groundwater Conditions and Deep Monitoring Wells<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The project involved complex groundwater conditions and required measurements at different depths.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional investigation methods could require considerable time and equipment, particularly when groundwater flow needed to be evaluated at different locations or depths.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project therefore required a groundwater flow measurement system that could provide:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Groundwater flow velocity measurement<\/li>\n\n\n\n<li>Groundwater flow direction measurement<\/li>\n\n\n\n<li>Deep-well measurement capability<\/li>\n\n\n\n<li>Stable field operation<\/li>\n\n\n\n<li>Efficient data acquisition<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML920 Groundwater Flow Velocity and Direction Instrument<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">To address these challenges, AIMOLI provided the <strong>AML920 Groundwater Flow Velocity and Direction Instrument<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 is designed specifically for measuring <strong>groundwater flow velocity and groundwater flow direction<\/strong> in monitoring wells and other groundwater investigation environments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The instrument combines groundwater flow measurement with field monitoring functions, allowing investigators to obtain groundwater flow information directly from the monitoring well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is suitable for applications including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Groundwater pollution investigation<\/li>\n\n\n\n<li>Groundwater flow measurement<\/li>\n\n\n\n<li>Groundwater flow direction determination<\/li>\n\n\n\n<li>Groundwater pollution source tracing<\/li>\n\n\n\n<li>Hydrogeological investigation<\/li>\n\n\n\n<li>Groundwater monitoring<\/li>\n\n\n\n<li>Environmental site investigation<\/li>\n\n\n\n<li>Groundwater remediation projects<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">How AML920 Measures Groundwater Flow<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 uses a groundwater flow measurement method designed for low-velocity groundwater environments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The instrument can measure groundwater flow velocity within a range of:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>0.001\u20131.0 m\/s<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This wide measurement range allows the instrument to be used for both relatively slow groundwater movement and higher groundwater flow conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For groundwater pollution investigations, the ability to measure low groundwater velocities is particularly important because groundwater movement can be significantly slower than surface-water flow.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Groundwater Flow Direction Measurement<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 can also determine groundwater flow direction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The instrument provides a flow-direction measurement accuracy of:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u00b12\u00b0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Accurate flow direction data can help investigators determine the potential migration direction of groundwater contaminants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When flow direction data are combined with groundwater quality testing results from multiple monitoring wells, investigators can better understand the possible distribution and migration pathway of groundwater pollution.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Key AML920 Measurement Parameters<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The main technical parameters of AML920 include:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameter<\/th><th>AML920 Specification<\/th><\/tr><\/thead><tbody><tr><td>Groundwater Flow Velocity

environments.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Measurement Depth Up to 300 Meters<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">One of the important capabilities of AML920 is its deep-well measurement capability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The instrument can support groundwater flow measurement at depths of <strong>up to 300 meters<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This makes it suitable for groundwater investigations involving:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deep monitoring wells<\/li>\n\n\n\n<li>Complex aquifer systems<\/li>\n\n\n\n<li>Industrial pollution investigations<\/li>\n\n\n\n<li>Hydrogeological surveys<\/li>\n\n\n\n<li>Groundwater source tracing<\/li>\n\n\n\n<li>Environmental remediation projects<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The actual operating depth depends on the monitoring well structure, cable configuration, groundwater conditions and specific equipment configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For deep-well applications, AIMOLI can provide configuration recommendations according to the project requirements.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Groundwater Pollution Source Tracing<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow velocity and direction are important when investigating the potential source and migration path of groundwater contamination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if several monitoring wells show different concentrations of a contaminant, investigators can combine:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Contaminant concentration data<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Groundwater flow direction<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Groundwater flow velocity<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">to evaluate the potential migration pathway of the pollutant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 therefore provides information that can complement conventional groundwater quality analysis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It does not replace laboratory contaminant analysis, but provides important <strong>hydrogeological flow information<\/strong> for interpreting groundwater pollution.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML920 for Groundwater Remediation Projects<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow information can also support groundwater remediation planning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before implementing a remediation project, engineers may need to understand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Groundwater flow direction<\/li>\n\n\n\n<li>Groundwater flow velocity<\/li>\n\n\n\n<li>Aquifer characteristics<\/li>\n\n\n\n<li>Potential pollutant migration routes<\/li>\n\n\n\n<li>Upgradient and downgradient conditions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 can provide groundwater flow measurements that help engineers understand these conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After remediation begins, repeated groundwater flow measurements can also be used as part of a broader groundwater monitoring program.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Non-Invasive Groundwater Flow Measurement<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Another important advantage of AML920 is its measurement approach, which is designed to minimize unnecessary disturbance to the groundwater environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is important because excessive disturbance can affect groundwater conditions and potentially influence measurement results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For environmental investigations where maintaining relatively stable groundwater conditions is important, a measurement system designed for low-flow groundwater environments can provide practical advantages.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML920 Technical Advantages<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">1. Wide Groundwater Flow Velocity Range<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 supports a groundwater flow velocity range of:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>0.001\u20131.0 m\/s<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows the instrument to measure both low-velocity and relatively high-velocity groundwater conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. High Flow Direction Accuracy<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The flow direction measurement accuracy can reach:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u00b12\u00b0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This provides useful directional information for groundwater pollution investigation and hydrogeological analysis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Deep Measurement Capability<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 supports measurement depths of up to:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>300 m<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This makes it suitable for deep groundwater monitoring wells and complex hydrogeological projects.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Designed for Groundwater Investigation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 is designed specifically for groundwater flow measurement rather than conventional surface-water flow measurement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5. Suitable for Pollution Source Tracing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow velocity and direction data can be combined with groundwater quality data to help evaluate potential contaminant migration pathways.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML920 Technical Development<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 is an independently developed AIMOLI groundwater flow measurement instrument.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to AIMOLI&#8217;s product information, the technology has obtained <strong>5 patents<\/strong> related to the product and its technical development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIMOLI has also accumulated experience in groundwater flow measurement and environmental investigation applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The instrument has been used in groundwater-related projects and environmental investigation applications in China.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Typical AML920 Application Workflow<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">A typical groundwater pollution investigation using AML920 can follow the workflow below:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1 \u2014 Monitoring Well Investigation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Confirm the monitoring well depth, diameter, groundwater level and geological conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2 \u2014 Equipment Configuration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Select the appropriate AML920 configuration according to the measurement depth and project requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3 \u2014 Instrument Deployment<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lower the instrument to the required measurement depth in the monitoring well.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4 \u2014 Groundwater Flow Measurement<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Measure groundwater flow velocity and flow direction at the selected depth.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5 \u2014 Multi-Point Measurement<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Where required, repeat measurements at different depths or monitoring wells.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6 \u2014 Data Analysis<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Combine groundwater flow data with groundwater quality and geological information.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 7 \u2014 Pollution Migration Assessment<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use the combined data to evaluate the potential groundwater flow pathway and pollutant migration direction.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Groundwater Flow Measurement Data and Pollution Investigation<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The greatest value of AML920 is not simply obtaining a single groundwater velocity value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The measurement data can become part of a larger groundwater investigation model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Monitoring Well A<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow velocity + flow direction<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Monitoring Well B<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow velocity + flow direction<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Monitoring Well C<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow velocity + flow direction<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Groundwater Quality Data<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Potential Pollution Migration Pathway<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This type of combined analysis can help environmental engineers better understand groundwater movement across the investigation area.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\"

remain stationary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once contaminants enter an aquifer, groundwater movement can influence the direction and speed of contaminant migration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a groundwater pollution investigation should ideally consider both:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Groundwater quality<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Groundwater movement<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Laboratory testing can determine what contaminants are present and at what concentrations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater flow measurement can provide additional information about <strong>where the groundwater is moving and how quickly it is moving<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML920 is designed to provide this
