Recent River Water Quality Information

( Dissolved Oxygen and

E.coli

in river waters )

What are Dissolved Oxygen and

E.coli

Dissolved Oxygen (DO) and

E.coli

are two important parameters indicating the general conditions of water and its health risk to the public.

Dissolved Oxygen indicates the total amount of oxygen dissolved in the river and stream water. Most aquatic 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.

E.coli

data at selected stations in 12 major rivers and streams are available on this web page.
