Sherbrooke Lake Water Quality Dataset

The Sherbrooke Lake Water Quality Program was implemented in fall 2017, with 2018 observing the first full sampling year. The program was designed by the Sherbrooke Lake Stewardship committee to obtain a baseline and monitor changes in water quality of the lake before, during, and after the development of a public access site. The program is managed by Coastal Action, with a group of trained volunteers collecting monthly and rainfall-dependent samples. Coastal Action also sits on the committee, in addition to a technical water quality expert, and citizen and municipality representatives from both the Municipality of Chester and the Municipality of the District of Lunenburg.

CIMP167_ Changes in dissolved organic carbon quality and quantity: Implications for aquatic ecosystems and drinking water quality for northern communities

Large stores of carbon are currently immobilized within permafrost, but a warming climate has the potential to release this carbon as dissolved organic carbon into the surrounding environment, with the potential to impact drinking water resources and aquatic health. Dissolved organic carbon (DOC) plays a number of important roles within the environment, ranging from acting as important biogeochemical and nutrient energy sources, to forming carcinogenic disinfection by-products as chlorine is added during water treatment. How DOC reacts is dependent upon its quality, yet little is known about either DOC quality or the fate of DOC in northern environments. The purpose of this research is to understand processes dictating DOC fate in northern aquatic environments in order to help predict how a warming climate could influence DOC quantity and quality. Using a space-for-time approach to represent differences between ‘warmer’ and ‘colder’ areas, water was collected from different aquatic environments including lakes, ponds, creeks, and subsurface peat water from three sites along a latitudinal gradient: Yellowknife, Wekweètì, and Daring Lake. In addition, baseline conditions were to be determined using historical geochemical records of the Yellowknife, Cameron, and Marian rivers. Water samples were analysed for concentrations of DOC and supplementary water quality parameters, in addition to water isotopes. DOC was characterized using ultra-violet and visible absorbance, size-exclusion chromatography, along with other techniques (i.e: PARAFAC and C:N ratios). In addition, laboratory experiments were conducted on select samples to see how easily DOC degrades via microbial or photolytic drivers. A wide range of DOC quality and quantity were encountered, with highest concentrations found in subsurface environments and lower concentrations in surface waters. Measures of DOC quality determined large, aromatic, humic molecules to be present within the subsurface around Yellowkni

Swim Drink Fish Toronto Community Monitoring Hubs

Swim Drink Fish staff have been collecting water samples for investigations, research reports, legal action, and media training since our first day back in 2001. Over the years, we’ve discovered that routine water quality monitoring at recreational sites has a special power. To know if waters are “swimmable”, you need to collect samples on a regular basis. That’s because recreational water quality is like the weather — it changes all the time. 

ake Ontario Waterkeeper began collecting water samples and testing for E. coli in 2016. E. coli is an indicator for sewage—the more E. coli present in a sample, the greater the risk to public health and the environment.

2021 is the sixth year of sampling at Toronto's Inner Harbour sites. Staff along with a group of trained citizen scientists sample the water every Tuesday and Thursday. We sample three main locations in the Inner Harbour In 2019, Ontario Place West Island Beach was also added as a site- which is one of the few accessible swimming locations in Toronto’s West End. 

In 2018 two teams of dedicated, trained citizen scientists started monitoring Humber Bay West Park in Etobicoke, and Algonquin Bridge and Snake Island on Wards Island. In 2021, First Street Beach was added as a sampling site. We have added the

Water Level Time Series, Choke Pass, Central Coast, BC, Canada (Provisional)

This dataset presents a time series of water level measurements made by an RBR Solo pressure sensor deployed by the Hakai Institute near the Calvert Island Research Station in the coastal region of Choke Pass. Sea Pressure collected by the instrument located just above the sea bed was then corrected to subtract the atmospheric pressure based on the Hakai Pruth Dock Weather Station. The resulting sea pressure was then converted to a depth with the Gibbs Sea Water TEOS-10 toolbox and subtracted by the mean water level measured at the location.
