Oxygen Depletion

Expert Response to Oxygen Depletion

Oxygen depletion of lakes, rivers and ponds can occur in a number of circumstances; also known as ‘oxygen crash’ the main contributors are pollution events and / or low water levels, particularly from droughts.

Oxygen depletion happens in aquatic environments as dissolved oxygen becomes reduced in concentration endangering aquatic organisms living in the system. Fish can be seen hanging at the water surface, sometimes gulping air.

Aeration is required to raise oxygen levels once depletion has been detected. This can be achieved by deployment of mechanical aeration devices or by the addition of hydrogen peroxide under controlled conditions.

Adler & Allan are experienced responders to oxygen crashes. We have expert consultants and operatives on hand to rapidly assess and deal with incidents.
