Drinking water is also tested by the GVRD for chemical contaminants as
well as turbidity. Additionally, the City operates an annual unidirectional
watermain flushing. This removes accumulated sediment and helps to
protect water quality.
Copies of the annual report on drinking water quality can be obtained
from the Engineering Department at New Westminster City Hall or on
the City of New Westminster’s website. To find out about future projects
aimed to maintain and ameliorate water quality within the GVRD, check

Other Environmental Concerns
They have an irritating odour and are another main cause of
smog.
Sulphur Oxides – Released by the combustion of some
fossil fuels. Sulfur dioxide is of particular importance because
it has a bad odour, irritates the upper respiratory tract and
leads to acid rain.
Particulate Matter – Includes dust, soot, ash, and pollen.
Large particles may irritate eyes, nose, and throat. Small
particles can be inhaled and cause respiratory problems
