Closing the groundwater protection implementation gap

Abstract

Complacency about drinking water security was the order of the day in the Province of Ontario, Canada, until the water supply of the community of Walkerton was contaminated in May 2000. Seven people died and 2300 became seriously ill when runoff from a nearby livestock farm contaminated an improperly constructed municipal well. The Walkerton tragedy, and similar incidents that have occurred in Ontario and elsewhere in North America and Europe during past decades, reflect serious implementation gaps in groundwater protection. In Ontario, many of these implementation gaps relate to shortfalls in local and provincial management capacity. Some local organizations are well served with skilled staff, leaders committed to groundwater protection, effective policies and plans, and sound databases. Unfortunately, many are not, particularly smaller communities in rural areas. Existing implementation gaps were exacerbated in the mid-1990s when the provincial government increased the responsibilities of local agencies while at the same time cutting funding and staffing levels in its own Ministry of the Environment. Recent local and provincial initiatives are beginning to close some implementation gaps. However, key challenges remain. This paper explores factors that shape local capacity for groundwater protection, and highlights ways in which capacity-related implementation gaps may be addressed. The focus is experiences in Ontario, Canada. However, lessons learned are broadly transferable. Chief among these are the importance of financial and technical support for delineation of source water protection zones; legal requirements for source water protection; senior government commitment and leadership; and enhanced local awareness of, and participation in, groundwater management.
