A decade of drinking water advisories: Historical evidence of frequency, duration and causes
Maintaining acceptable drinking water quality is a challenge in Canadian First Nations communities, resulting in many residents experiencing frequent drinking water advisories (DWAs). Detailed information about drinking water systems on reserves was combined with 11 years of advisory data to consolidate existing data sets and to understand historical trends. Patterns related to the frequency, duration and causes of advisories are summarized. The results show that the total number of DWAs has increased over the last decade despite recent attention, policy renewal and funding commitments. The frequency and duration of DWAs vary according to location, source type, system size and operator certification. Facilities relying on surface water have a higher likelihood of experiencing DWAs, and systems without fully trained operators are more likely to experience long-lasting DWAs. Findings indicate the need exists to maintain an up-to-date record of First Nations system information to close existing data gaps.
