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.

Monitoring DNAPL & Water Level

One way to measure DNAPL and water levels is to collect real-time data with Level TROLL Instruments. By installing one Level TROLL in the DNAPL layer and a second Level TROLL in the water column, it is possible to calculate the thickness of the DNAPL layer based on the difference in fluid densities.

Using Data Loggers in Soil Vapor Extraction & Dual-Phase Extraction Systems

Use Level TROLL^® and BaroTROLL^® Instruments or the TROLL 9500 to monitor water levels and barometric pressure in SVE and DPE systems. These economical remediation methods are designed to remove VOCs from contaminated soil and groundwater.

Sampling Groundwater

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