In Ontario approximately 20% of the
population gets their drinking water from a non-municipal drinking water
source; these include small drinking water systems (SDWSs). The Ontario
Ministry of Health and Long-Term Care oversees the systems and they are
inspected by public health inspectors. SDWSs are particularly vulnerable to
contamination and PHIs face unique challenges during inspections.. The
challenges include: fewer protective
measures in place than larger systems, the remote and isolated locations of many
systems, the cost of operating a treatment system for a small number of
consumers, poor access to operator training, and low retention of knowledgeable
The topics addressed in this presentation
will assist the PHI in identifying and prioritizing protection efforts and
education opportunities fundamental to improving the safety of SDWS, including:
outbreak trends, operator ability, training needs and factors related to SDWSs
having positive E.coli test results.
the characteristics that put SDWSs at greater risk for contamination
the characteristics and behaviours of the SDWS operator that can influence the
security of the water supply
Discuss the role PHIs
can play in improving the safety of the water supply in SDWSs
