Client: Pioneer Construction

ADS undertook groundwater and local surface water quality monitoring during dewatering of excavations within aquifers <500m away from potable water abstractions. Strict water quality trigger values were set for each water body. Monitoring included telemetric continuous monitoring of key parameters using aquatrolls, weather monitoring, regular confirmatory low flow sampling of groundwater and water sampling of lakes and streams to demonstrate no adverse impacts by construction.

This project delivered a variety of technological solutions to assure stakeholders that below ground risk was being managed effectively on site. The works were completed within a busy construction period. Stakeholders were updated regularly and the construction activities completed without interruption.

ADS was commissioned to support the contractor to deliver the agreed groundwater and local surface water monitoring plan. All planning
requirements were met and agreement with key stakeholders including the Environment Agency, Thames Water and Affinity Water secured.
