The Canadian Council of Ministers of the Environment (CCME) is looking for input into the draft Canadian Groundwater Quality Guidelines for the Protection of Environmental and Human Health for 101 contaminants of concern. It is available for public review and comment until January 10, 2020.
Hi all…following up from the WHO report on microplastics that I recently circulated, the UK Water Industry Research Limited has just released a report entitled “Sink to River - River to Tap - A review of potential risks from nano-particles & microplastics.”
Hi all…the WHO has released a lengthy report entitled ‘Microplastics in Drinking Water’. It is a good compilation of potential issues associated with microplastics and is available for free download. There is also an Information sheet: Microplastics in drinking-water which provides key messages and answers to some common questions. This may be even more useful than the report for some of you.
Hi all…on the heels of Health Canada’s new guideline for lead in drinking water, Canada’s National Collaborating Centre for Environmental Health has prepared an 8-page document entitled “Testing for Lead in School Drinking Water-A Summary of Sampling Protocols.” Table 1 is a “Summary of sampling protocols for testing lead in school drinking water developed in Canada [...]
Happy New Year all! There has been a lot of interest in microplastics in water recently and it looks like this will be one this year’s hot research areas. They have the potential to be impactful on human health but a lot of science remains to be done.
Finally a large scale study that confirms drinking water fluoridation prevents dental caries has been published in the American Journal of Preventive Medicine. Unfortunately, it also confirms that those with better teeth had higher blood lead levels.
Hi all…while there is some information on the effects of backwashing drinking water biofilters with chlorinated water, there are very few papers on backwashing such biofilters with chloraminated water. In a just published paper in WST: Water Supply researchers trying to determine the cause of rapid monochloramine decay observed in treated water concluded that “backwashing of media filters with [...]
Hi all…The USEPA released a report in Feb 2017 entitled “Sampling Guidance for Unknown Contaminants in Drinking Water.” If you’re like me, it’s one of those reports that probably won’t make it to the top of your reading list until you really need it. You can save some time during a contamination event by downloading it [...]
The USEPA’s Contaminant Candidate List 4 (CCL 4) was finalized November 17, 2016. The CCL is a list of contaminants that are currently not subject to any proposed or promulgated national primary drinking water regulations, but are known...
Hi all…the Water Research Foundation has just released a report entitled “A Methodology for Locating and Managing Dynamic Potential Source Water Contaminant Data – Project 4581.” “The purpose of the project was to develop and demonstrate a methodology for identifying potential sources of contamination upstream of drinking water intakes, particularly from above ground storage tanks [...]
