Remediation specialists require accurate water level and water quality data to characterize sites and to assess treatment strategies.

In-Situ Remediation

Evaluate treatment progress by deploying the TROLL^® 9500 water quality instrument into 2- and 4-inch boreholes. Configure the TROLL 9500 with sensors suited to your project.

For example, you can deploy a sub-2 inch TROLL 9500 with the RDO^® optical DO sensor, plus sensors for pH/ORP, conductivity, and temperature.

Soil Vapor Extraction

Use Level TROLL^® and BaroTROLL^® instruments to monitor water levels and barometric pressure in SVE systems. SVE is an economical remediation method for removing volatile hydrocarbons from contaminated soil and groundwater.

Low-Flow Groundwater Sampling

Use low-flow groundwater sampling to improve sample quality and representativeness, while reducing wastewater generated by sample purging. Use the In-Situ Flow-Sense system to automate sensor calibration, data collection, parameter stabilization, and report generation. You'll save time and money by digitally organizing your sampling event.
