A collaborative approach to Groundwater Protection: The Rural Water Quality Program for Waterloo Region
Canadian Water Resources Journal Revue canadienne des ressources hydriques, 2014Co-Authors: Hugh Simpson, Rob C. De LoëAbstract:Source water Protection (SWP) efforts in many jurisdictions focus primarily on protecting municipal Groundwater wells through a highly technical process known as wellhead Protection planning (WHPP). Less attention has been given to implementing a broader approach for protecting Groundwater supplies both within and outside municipal wellhead Protection areas through stewardship and other approaches that engage diverse stakeholders. Technical approaches to drinking-water safety are necessary, but increasingly it is recognized that they are not sufficient in the context of a complex problem such as Groundwater Protection. There is growing recognition globally that solutions to complex problems require decision-making processes that involve the integration of expert science, local knowledge and community beliefs and values. In this paper, the example of Groundwater Protection in the Region of Waterloo, Ontario, is used to illustrate how collaborative approaches can facilitate the integration of scientific and...

Closing the Groundwater Protection implementation gap
Geoforum, 2005Co-Authors: Rob C. De Loë, Reid KreutzwiserAbstract: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.

Groundwater Protection on Long Island, New York: a study in management capacity
Journal of Environmental Planning and Management, 2004Co-Authors: Rob C. De Loë, Danielle K. LukovichAbstract:Through their powers to regulate land use and their responsibilities for public water supply, local governments are critical players in Groundwater Protection. Unfortunately, the demands of Groundwater Protection are high, and many local governments do not have the ability or capacity to develop and implement appropriate management strategies. This paper analyzes Groundwater Protection experiences on Long Island, New York, a place where Groundwater dependence is high, and threats to Groundwater are serious. Long Island's experiences highlight the need to approach capacity building for Groundwater Protection broadly, concentrating on factors such as political commitment and citizen support; enhancement of local technical competency through linkages and support from state and federal governments; and strengthening of institutional arrangements at all levels.

Local capacity for Groundwater Protection in Ontario.
Environmental management, 2002Co-Authors: Rob C. De Loë, Sandra E. Di Giantomasso, Reid KreutzwiserAbstract:Preventing Groundwater contamination is vastly cheaper than remediation. Recognizing this, attention in water and land management agencies in North America increasingly turn to Groundwater Protection. Local agencies, such as municipalities and watershed management districts, are vital to successful Groundwater Protection, but they face daunting challenges. In the United States, senior governments have recognized these challenges and provide considerable support for local agencies. In Ontario, Canada, local agencies are, to a much greater extent, on their own. The aims in this paper are to analyze factors that shape local capacity for Groundwater Protection, focusing on Ontario, and to recommend avenues for capacity building. Interrelationships among five dimensions of capacity (technical, financial, institutional, social, and political) are explored through an analysis of three smaller Ontario communities: City of Guelph (population 93,400), Town of Orangeville (population 22,188), and Town of Erin (population 11,000). Size clearly influences capacity for Groundwater Protection. However, other considerations unrelated to size appear to be as important. These other factors include the ability to form horizontal and vertical linkages with external agencies, political leadership and commitment, and citizen involvement. Thus, smaller communities in Ontario (and other jurisdictions with limited senior government support) would do well to focus on these areas at the same time as they develop their technical, financial, and institutional capacity.

Groundwater modeling and demarcation of Groundwater Protection zones for tirupur basin a case study
Journal of Hydro-environment Research, 2011Co-Authors: R. Saravanan, R. Balamurugan, M.s. Karthikeyan, R. Rajkumar, N.g. Anuthaman, Navaneetha A GopalakrishnanAbstract:Abstract Groundwater is a renewable resource and has to be protected from contamination. The concept of a zone of Protection for areas containing Groundwater has been developed and adopted in a number of countries. One such area is Tirupur, (Tamil Nadu, India) which is an arid region and rapid expansion of the textile industry has taken place with no associated development of supporting infrastructure or institutional capacity. Textile production, particularly dyeing and bleaching is water intensive and generates large quantities of effluent. One of the most significant challenges for the Tirupur textile industry today is water for bleaching and disposal of effluent. Demarcation of Groundwater Protection zones has become necessary to facilitate recharging of the aquifer to meet the water demand. These zones are considered sensitive zones and should be free from activities such as the Groundwater over exploitation, effluent discharge and construction of barriers. Groundwater flow for Tirupur Block was simulated using visual MODFLOW version 4.1. The model was run for the year 1998–99 with transient flow condition. Taking June 1998 water level as initial head, the model was run to simulate water level up to May 1999 and validated with the observed data for all the six wells which are distributed over six different zones. The results obtained from the simulation were used to assign the ranks and weights for overlay process in Geomedia environment. The consequent higher index values indicate the sensitivity zone influencing recharge to the aquifer which should be demarcated as Groundwater Protection zones. This Groundwater Protection zone will be designated as pollution free zone for better management of the aquife.
