Recent Marine Water Quality Information
(Dissolved Oxygen and
E.coli
in marine waters)
What are Dissolved Oxygen and
E.coli
?
Dissolved Oxygen (DO) and
E.coli
are two important parameters indicating the general conditions of the water and its health risk to the public.
Dissolved Oxygen indicates the total amount of oxygen dissolved in the water. Most marine organisms need oxygen for respiration and maintenance of life.
E.coli
is a kind of bacteria found in human faeces, often used as an indicator of sewage pollution. A higher
E.coli
count indicates greater faecal contamination and higher health risk.
The recent DO and
E.coli
data at selected stations in 10 Water Control Zones are available on this web page.
