Ensuring that pollutants from mining activities do not enter surrounding natural water bodies is a key issue in environmental monitoring and regulatory compliance.

Hydrolab multiparameter sondes can measure a variety of parameters pertaining to mining operations including conductivity and specific conductance, total dissolved solids, salinity, pH & Redox potential (ORP), chloride, dissolved oxygen, and turbidity. Both OTT and Hydrolab sensors can be setup with telemetry options to trigger alarm messages if certain parameter thresholds are breached.

OTT groundwater level sensors can measure current water levels around mining operations and support systems that regulate and pump water levels around mining sites. Groundwater quality can also be monitored, typically with conductivity as a surrogate measurement.
