BC policy on point of use and point of entry water treatment: An assessment and progress report

Description:BC policy on point of use and point entry water treatment: an assessment and progress report. Presenter: Mohammed DORE, Ph.D., Brock University and Res'eau-Waternet. In BC, from 2001 to 2012, there were 20,749 reported Cryptosporidium cases, 8,162 cases of Giardia and 1671 Shiga toxigenic E. coli cases (BC Centre for Disease Control, 2010 and 2012). Almost all of these outbreaks continue to be in small communities. Many of the small systems are under Boil Water Notices, mainly due to lack of treatment. One alternative is to promote the use of Point of Use (POU) or Point Entry (POE) treatment. In this presentation we review the regulatory requirements in BC for the use of POU/POE that requires that 100% of the communities sign a service agreement, which raises costs. We review the progress that has been made in the Interior Health Authority and its “Small Systems Strategy” and action plan. We consider one case study where the community remains on a Boil Water Notice but part of the community uses POU/POE. We consider the implications of allowing that sort of flexibility whereby a household could “go it alone.” Many POU systems with NSF certification # 53 and 55 are affordable, with light maintenance. Finally we attempt to assess the current progress in enhancing water safety in the Interior Health Authority both through POU/POE and the new strategy of “engagement and outreach.” One indicator of progress is the number of Boil Water Notices, which in part is due to more water systems being covered by the data. We show what progress that has been made so far and what remains to be done.
