Groundwater Sampling, Monitoring and Testing Frequency
Water quality and data are only as good as the tools used to measure them. Being able to accurately characterize and evaluate water quality and the extent of any potential contamination is incredibly important during any well drilling or direct push tooling operation. One of the leading brands in the industry, Geoprobe® Systems, offers a number of groundwater sampling tools and accessories that can help characterize the water quality and contamination during environmental assessments and investigations in unconsolidated soils and sediments.
Water samples from groundwater occurs over five steps: sampling preparations, accessing the well before sampling and securing the well after sampling, measuring the water level, purging the well, and finally, collecting and delivering the water sample for evaluation.
Certain types of groundwater samplers are installed temporarily (SP16, SP22, Mill Slotted Rods) allowing for quick sample collection along with slug testing capabilities, then the sampler is removed decontaminated, and used at the next location.
To help monitor levels of contaminants in groundwater, a product calledGeoprobe Prepacks are available that work well for both long and short term groundwater monitoring. They are available in a variety of sizes and are quick to install.
The question of how often you should sample your water depends on the purpose for the sample. Shallower wells, particularly domestic wells will smaller pumps should be tested once or twice a year.
Most groundwater samplers permit you to conduct bottom-up grouting to meet regulatory requirements for borehole abandonment. These simple, cost-effective tools have changed the way many environmental assessments and remedial investigations are conducted. Simpler can be better… smarter… and less expensive.
