A primary goal in environmental cleanup at HPNS is to protect public health and the environment over the long term. The Navy’s cleanup plans at HPNS accounted for sea level rise because of climate change, thereby protecting cleanup remedies and public health and the environment. Various engineering methods are constructed or used to manage and prepare for sea level rise across HPNS, including the following:
- Installation of below- and above-ground walls to prevent water and soil movement and limit erosion
- Increases in the elevation of HPNS shoreline
- Excavation and removal of contaminated soils
- Treatment of contaminated groundwater
- Long-term monitoring and maintenance to ensure that treatment technologies remain effective.
