Water Quality Recreation and Aesthetics 8.1 Effects There
are a number of publications indicating that people avoid highly
coloured and/or turbid waters (see BC Environment 1998a). To
our knowledge, no effects of total or dissolved organic carbon
to the recreational quality of waters other than these visual
aesthetics effects have been documented.
There are no criteria for total and dissolved organic carbon specific to recreation and aesthetics available from any other jurisdiction.
No water quality criteria are proposed for total and dissolved organic carbon in waters used for recreation.
The major
requirements for recreational waters are that they contain
low numbers of organisms posing health risks (e.g., fecal coliforms,
pathogens), are free of nuisance organisms, and are aesthetically
acceptable (i.e., low colour and turbidity, free from oil and
grease). Dissolved organic carbon is often closely correlated
with colour, while total organic carbon may be correlated with
turbidity (e.g., Effler et al. 1985; Gorham et al. 1986; Evans
1988). However, water quality criteria for colour and turbidity
have been developed (BC Environment 1998a,b) and these more
directly address the issues posed by elevated levels of organic
carbon in recreational waters.
