Future requirements are touched on. Provincial water quality objectives are described and compared with international drinking water standards.doi:10.1139/l75-015Lumsden, T. W.Knowles, W. L. C.Canadian Journal of Civil Engineering
Metal concentrations in water decreased by 40鈥 75% in the tributaries between May 1988 and 2000, which resulted in decreased metal concentrations that were, in 2000, all below the Provincial Water Quality Objectives. Measured sediment concentrations exceeded the Lowest Effect Levels (LEL) for all ...
Higher-level leadership opportunities in Ontario Parks often require knowledge of enforcement programs, so experience as a park warden is a great step along the way! Park wardens gain experience in resource management protection, public safety, enforcement, Ontario Parks policies, provincial acts and l...
In the Bay of Quinte water, Provincial Water Quality Objectives (PWQO) were exceeded only on a small portion of samples for copper, cadmium, iron, zinc, and phenols; indeed, most samples showed undetectable amounts of arsenic, cadmium, mercury, nickel, and lead. Metal levels in Bay of ...
Water quality data were obtained from the Ontario Provincial Water Quality Monitoring Network while historical land use was reconstructed from agricultural census reports, historical land cover maps, and modern remotely sensed datasets. Urban cover increased, although percent increases in urban cover were ...
Eliminating lakes with nickel and copper concentrations above provincial water quality objectives (PWQO's) improved the relationship between Daphnia ephippia size and the abundance of planktivorous fish (PL-CPUEn) (r = 0.60, p<0.05). The CPUEn was inferred in the lakes by applying the mean ...
The water quality parameters were compared to the Provincial objectives to identify potentially degraded water quality. The total aluminum and iron concentrations exceeded the objectives at several stations which were compared to the remaining stations with concentrations below the objectives, as well as ...
3) to conduct a targeted in-depth examination of the challenges to enhancing water security with respect to federal, provincial and First Nations water institutions and arrangements; and 4) to develop strategies based on best practices for more effective water collaboration through integration of the...
Other parameters in shoreside/nearshore samples met their respective provincial/federal objectives/guidelines; however, instream E. coli and specific conductivity levels were elevated, reflecting the effects of urbanization. The Lake water temperature moorings recorded lake stratification dynamics, including ...
The main objectives of the survey were to determine the quality and safety of drinking water for farm families, and determine the effect of agricultural management on groundwater quality at a provincial scale. Four farm wells were chosen in each township where >50% of the land area was used ...
