Regarding the tenth anniversary of the Walkerton tragedy : from the K-W Record ..."The simple recognition for source protection was a big step , says Mark Servos , a University of Waterloo biology professor and scientific director for the Canadian Water Network. You had to have a multi-barrier approach, he says. Don't just treat it. Don't have it in the water in the first place."

This multi barrier approach essentially means that the failure or breakdown of one component of your water protection system will not mean immediate negative consequences or even threats to the water users.For example if your granulated activated carbon (gac) filters need regeneration, as long as you have sucessfully kept a nearby industrial contaminated site, through proper remediation, from contaminating the drinking water aquifer, then you will be OK. to change out your carbon etc.. This is merely as an example. Hopefully you do have some storage capacity available while doing routine maintenance.
ReplyDeleteI enjoy your site, however i find some of the terminology a little too specific, but i will get through it.
