Water Quality Data Logger for Monitoring Coal Mine Runoff

CLEVELAND - June 28, 2022 - PRLog -- High Salinity Water Runoff Monitoring Solutions

CAS DataLoggers provided a water quality data logging solution for an open-cut coal mine to monitor high salinity water runoff into local retaining ponds. The water from these retention ponds could only be released into the local river system when it was of sufficient quality so as to have no effect on the irrigation supplies for the surrounding farming district. Therefore it was necessary to closely monitor water quality in the lagoons for several key parameters including pH, salinity, and turbidity.

Installation

The coal mine choose a dataTaker DT80 Universal Input Data Logger to monitor the quality of the coal mine water discharge. The data logger was mounted in a weatherproof enclosure suitable for outdoor exposure at the monitoring site. The DT80 was connected to multiple sensors to allow measurement of conductivity (salinity), turbidity, pH, and water levels as well as thermocouples for water and air temperature.

Usage

The DT80 data logger is a very cost-effective device for water quality and environmental monitoring. It offers expandability to 100 channels or 300 single-ended analog inputs, and also features digital channels, high-speed counter inputs, SDI-12, and serial sensor channels for connection to almost any type of analog or smart sensor.

Benefits

In this water quality monitoring application, remote telemetry via a Microhard LTE Cube cellular modem was used to create a wireless link from the logger to the central PC in the mine's office. This connection allowed personnel to remotely observe changes in water quality in real-time during water management operations such as mixing water from different sources. For ongoing operations, periodic connections were made to the dataTaker for mine water discharge monitoring.
