Aardvark project

Water Quality Survey

Location: Mullion Harbour, Cornwall	Client: Envireau/National Trust
Date: November 2004	Sector: Water and Environment

Coastal Scene

To design and execute a sampling strategy to collect water flowing underneath the harbour complex. To test an erosion pathway.
To provide onsite analysis of conductivity pH and a volume assessment
Liaise with client and remediation teams.

Mullion Harbour located on the south tip of the lizard Peninsular. The structure is partially failing thought to be due to a combination of physical and chemical damage caused by underground water flow and wave impact at the base of the structure.
Aardvark was approached by the National Trust to determine the causes using a micro boring rig. The team developed a sampling strategy to take into account the harsh site conditions and collected samples along the line of the harbour wall despite time constraints of tides and gathering storm conditions.
Samples were tested on site and a summary report was produced for the client detailing the results of the water analysis outlining the likely impacts of the findings related to the geology of the harbour.
