There is a growing concern regarding cyanobacteria in surface waters and the risks of cyanobacteria entering our drinking water treatment systems. This webinar discusses the challenges and knowledge gaps for treating cyanobacteria in small drinking water systems and summarize the results of a pilot testing project. The Centre’s pilot testing project investigated the effect of small drinking water treatment technologies on the removal of cyanobacteria and cyanotoxins using a natural bloom event.Read More

Personal cultivation as described by the proposed Cannabis Act (2017) will permit adults to cultivate up to four cannabis plants per household. This provision is intended to both promote equity by facilitating access to legal cannabis, particularly when retail outlets are difficult to access, and to undercut the black market. However, indoor cultivation and processing of cannabis may also introduce or exacerbate certain environmental health risks in the home. This document identifies health and safety concerns that may be relevant to personal cultivation after legalization – that is, legal home growing and the associated health risks.
Although this information may be of relevance to the public at large, the evidence presented here has been synthesized and organized for policy- and decision-makers, environmental and medical health officers, and other public health professionals. This review thus serves as a launching point for considering both wide-scale and regionally oriented preventive actions to mitigate the environmental health risks that may arise from growing at home.
Primary inquiry: Information regarding tebori, a traditional form of Japanese “hand-poke” tattooing; requesting information regarding infection control and inspection.Read More
Primary inquiry: What information is available regarding the environmental health-related risks of colonics in the academic literature, and how can environmental health practitioners help reduce these risks?Read More
Primary inquiry: In Canada, as in many other countries, cemeteries are required to be setback a certain distance from waterbodies to protect drinking water sources from contaminated liquids that can arise from the decomposition of bodies after burial. What is recommended as a safe setback distance? What is the rationale for the setback distances used throughout Canada?Read More
Primary inquiry: Small horticulture growers have been watering their crops with surface water containing a cyanobacterial bloom, before selling their crops at local markets. 1. Can irrigation of food crops using surface water affected by cyanobacteria blooms result in bioaccumulation of cyanotoxins in these crops? 2. Can cyanotoxins bioaccumulate to a concentration that might cause a public health concern? Please note: The information provided here is for the purpose of addressing a specific inquiry and is not subjected to external review. The information offered does not supersede federal, provincial, or local guidance or regulationsRead More
Splash parks, also known as splash pads, spray parks, or wet decks, have gained in popularity over the last decade. These interactive parks are artificially created depressions or basins into which water is sprayed, splashed or poured onto visitors; water is not permitted to accumulate, but instead drains immediately out of the play area. Splash parks may take one of two basic designs, which influences the associated public health risks. Non-recirculating or flow-through parks discharge the water directly to waste and present a relatively low risk to their users as the design is based on using fresh potable water. In contrast, recirculating parks collect water in an underground tank, apply some form of water treatment, and re-use the water again. This presents an increased risk of contamination and disease transmission that can be mitigated through proper design and operation.
The objective of this document is to identify risks to public health posed by splash parks, the factors that contribute to this risk, outline practices that can mitigate these risks, and summarize the existing regulatory environment for these facilities. It focuses on epidemiological risks rather than physical hazards such as slip and fall injuries, heat stroke, and foot lacerations.
What are cyanobacteria? Are cyanoblooms preventable? Who is at risk and how does exposure occur? Is there testing for cyanotoxins? This NCCEH document provides a brief outline of these key questions related to cyanobacteria and the toxins they produce.Read More
