Management strategies. All water utilities should implement a risk management approach, such as the source-to-tap or water safety plan approach, to ensure water safety (CCME, 2004; WHO, 2011, 2012). These approaches require a system assessment to characterize the source water, describe the...

Epidemiological studies investigating the association between GI and bacterial fecal indicators during primary contact recreational activities in fresh and marine waters (1984-2016)

These documents provide guideline values for specific parameters used to monitor water quality hazards and recommend science-based monitoring and risk management strategies.

Several significant changes have been included in the current fecal indicator guidelines. This includes moving away from using GM and SSM's to using BAVs for day-to-day beach management (based on data from the most recent epidemiological studies), recommending PCR-based monitoring methods in...

Indicators can be used for various purposes as part of a recreational water quality management plan. Fecal indicators signal the likely presence of fecal contamination. Common fecal indicators include E. coli and enterococci, as well as source-specific fecal indicators, such as the HF183...

Guidelines for the fecal indicator bacteria Escherichia coli (E. coli) and enterococci have been developed for recreational areas used for primary contact activities (see Table 1 and Table 2). These values consider both the potential health risks and the benefits of recreational water use in...

The Guidelines for Canadian Recreational Water Quality are comprised of multiple guideline technical documents that consider the various factors that could interfere with the safety of recreational waters from a human health perspective. This includes technical documents on understanding and...

This guideline technical document evaluated the available information on fecal indicator organisms in recreational waters with the intent of updating/recommending guideline values. The purpose of this consultation is to solicit comments on the proposed guidelines, on the approach used for their...

There are a number of mitigating measures for vapour releases at gasoline stations based on the Environmental Code of Practice issued by the Canadian Council of Ministers of the Environment (CCME 1991). These measures, which include Stage 1 vapour recovery (Figure 6), were designed to reduce the...

Uncertainties in evaluating the risk to human health: Recent Canadian benzene concentrations based on monitoring data at or near gasoline station operations were not available. Estimates of benzene concentrations emitted from gasoline stations were based on modelled values of total evaporative...

Conclusion: In this report, the short-term benzene releases occurring due to tanker truck unloading of gasoline into storage tanks at gasoline stations and long-term releases of benzene from gasoline station total evaporative losses are estimated. For those living in the vicinity of the gasoline...

Air pollution is a major contributor to the development of disease and premature death. It also represents the largest environmental risk factor to human health (WHO 2016). Exposure to air pollution increases the risk of dying prematurely from heart disease, stroke and lung cancer.

Air pollution is recognized globally as a major contributor to the development of disease and premature death and represents the largest environmental risk factor to human health (WHO 2016). Exposure to air pollution increases the risk of premature mortality from heart disease, stroke and lung...

The purpose of this guidance is to summarize ways to remediate, maintain and improve indoor air quality in office buildings. This guidance provides practical recommendations to address and respond to potential IAQ problems, including guidance for reducing pollutant sources and properly operating...

Indoor air quality refers to the quality of the air in an indoor environment, such as inside a building, particularly as it relates to the health and comfort of occupants. Indoor air quality is the result of the constantly changing complex interactions among building systems, the environment...

Building operators and those responsible for IAQ should be knowledgeable about the ventilation system design and operation, which includes the outdoor air supply, outdoor air quality, filters and filtration efficiency, space planning, equipment maintenance, controlling other contaminant pathways...

Poor indoor air quality can affect your health. The most effective way to improve your indoor air is to identify activities that can contribute to poor indoor air quality and remove or reduce the sources of indoor air pollutants.

Stewardship refers to overseeing and being responsible for the care and maintenance of property. Building operators and the employer are often able to directly and positively impact IAQ through building stewardship. By understanding IAQ and the interaction between products, furnishings,...
