Groundwater management and protection programs rely on accurate water quality data. In-Situ^® Aqua TROLL^® instruments and TROLL 9500 instruments can help you assess groundwater quality.

Aquifer Storage & Recovery

Monitor long-term water level and conductivity values during cycles of injection, storage, and retrieval with the Aqua TROLL 200 instrument.

Low-Flow 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.

"When LCU participated in beta [field] testing of the new multi-parameter Aqua TROLL 200, it was evident the sensor could complement the utility's ASR program." – Randy Edelstein, hydrologist at Lee County Utilities in Florida.

Road Salt Runoff

Track environmental impacts of chloride runoff on urban streams, rivers, and aquifers with Aqua TROLL 100 and 200 instruments.

Saltwater Intrusion

Capture spikes in conductivity due to penetration of saltwater by using an Aqua TROLL instrument and the event sampling mode.

Tracer Studies

Track the direction and speed of laminar groundwater flow with In-Situ instruments.
