Willow Baseline Water Quality Monitoring

This is the initial water quality sampling effort performed at select lakes in the proposed Willow development area in support of environmental monitoring. No oil and gas facilities—gravel or pipeline infrastructure—have been constructed in Willow; only winter exploration activities have been performed. Lakes were selected due to their proximity to proposed pads and infrastructure development.

The water quality monitoring program included in-situ sampling of the five lakes for temperature, conductivity/specific conductance, dissolved oxygen (DO), salinity, turbidity, and pH. Water samples were collected at each lake for laboratory analyses of Per- and Polyfluoroalkyl substances (PFAS); dissolved hydrocarbons: diesel range organics (DRO) and residual range organics (RRO); zinc; and Resource Conservation and Recovery Act 8 (RCRA 8) metals.
