Utilizing dedicated low flow groundwater pumps instead of a single pump shared between bores offers numerous advantages, enhancing efficiency, accuracy, and cost-effectiveness in groundwater monitoring and sampling processes:

  • Reduced Purge Volumes: With dedicated pumps, purge volumes are minimized, leading to significant cost savings and avoiding cross-contamination between sampling points.
  • Enhanced Sample Quality: Less disturbance to the water column results in better quality samples and increased confidence in the accuracy of analysis outcomes.
  • Time Savings: Significantly reduces the time required for sampling at each bore, optimizing field operations and resource utilization. Less time is spent adjusting drive-vent cycles. Dedicated equipment streamlines data acquisition by eliminating the need to lower equipment into boreholes, reducing time and effort.
  • Lower Training Requirements: The simplified operation of dedicated pumps reduces the need for highly trained technicians on-site, lowering operational costs.
  • Avoidance of Cross-Contamination: Dedicated pumps prevent contamination between bores, ensuring the integrity of samples and boosting confidence in monitoring results.
  • Enhanced Safety: Reduced on-site sampling time enhances safety by minimizing exposure risks for personnel.
  • Cost Savings on Tubing: Dedicated pumps can lead to savings on tubing costs over time, contributing to overall operational efficiency.
  • Compatibility with Dedicated Pump Well Heads: Works seamlessly with dedicated pump well heads, further streamlining sampling processes and ensuring ease of use.

From EPA groundwater sampling guidelines:

Consider using a dedicated sampling device permanently installed in the bore. This approach can reduce time (and cost) involved in set-up, sampling and decontamination. A dedicated pump also lets you use passive sampling techniques, improving the representativeness of groundwater samples [Reference: EPA ‘Groundwater Sampling Guidelines 669.1 Feb ‘22]
