[Title: Edithvale and Bonbeach Environment Effects Statement Groundwater Quality]
Tony - EES Groundwater Lead, LXRA Technical Advisor - AECOM-GHD joint venture
An Environment Effect Statement, an EES, is an assessment of the potential impacts of a project.
[Vision: Time lapse of construction work on rail corridor]
It allows the government to make a decision around whether a project should proceed.
[Vision: Railway crossing and stop sign with train passing through]
The focus of this EES is the level crossing removal projects proposed at Edithvale and Bonbeach.

[Groundwater levels - groundwater quality - edithvale-seaford wetlands]
Specifically it focuses on three areas: Groundwater levels, groundwater quality, the Edithvale-Seaford Wetlands and other ecosystems.

[Level Crossing works would not impact the Edithvale-Seaford Wetlands]
[Vision: Aerial view of wetlands]
Our study has found that the level crossing removal projects wouldn’t impact upon the Edithvale-Seaford Wetlands, and other impacts relating to groundwater were minor and could be managed.
[Vision: Tony speaking]
Groundwater is water that occurs underground.
[Vision: Ducks in wetland]
It occurs when water from rainfall or rivers or other sources seeps into soil and rocks.
Groundwater is essential for many ecosystems at Edithvale and Bonbeach including the wetlands.
[Vision: Diagram of Edithvale groundwater design technique]
Our study predicted possible changes to groundwater levels as a result of the rail trenches required for the Edithvale and Bonbeach level crossing removal projects.
[Vision: Tony speaking]
At Edithvale, changes to groundwater quality were not predicted to occur due to the design we are using.
At Bonbeach, the predicted changes to groundwater levels have the potential to expose naturally occurring coastal acid/sulphate soils to air.
[Vision: Bonbeach: extremely low risk to the environment and health]
[Vision: Staff member working on computer analysing effects]
This could impact groundwater quality.
However, the EES concluded that the risk to the environment or human health was extremely low or negligible.
