Larnaca Marina

The Problem

Larnaca Marina’s sediment was contaminated with TPH (total Petroleum Hydrocarbons).
This is caused by the heavy movement of boats entering and exiting the marina, and also motor and oil spills while refueling their vessels.

Additional contamination is caused by runoffs (organic material), paints & solvents while the owners maintain their boats, as well as sewage contamination.

The end result is a polluted marina, with foggy waters, increased toxic algae bloom and very little to none aquatic life. 

The Solution

The Department of Environment of the Republic of Cyprus requested that marine sediment samples be collected from the sea floor of the Larnaca Marina, before and after water treatment.

An analysis was performed on marine sediment samples collected in order to determine the effect (positive or negative) of the treatment on the sea floor marine environment with respect to levels of Total Petroleum Hydrocarbons (TPH).

Our samples indicated a contaminated sediment with TPH reaching extravagant levels.

In just a period of 6 months VTW managed to achieve 95% reductions in the TPH levels, resulting in a significant drop of pollutants within the marine sediment and restoration of aquatic life.
