Impact of Agricultural Pressures on Municipal Groundwater Quality in the Province of Quebec
农业压力对魁北克省城市地下水质量的影响
自2002年新的地下水集水区法规发布以来
在魁北克省,市政府现在必须
描述井口集水区,以保护其水源
小城市面临着巨大的挑战。地下水公用事业
因此,资料来源需要描述其含水层的特征
以及确定油井的整个贡献区(ZOC),以及
地下水移动时间边界。
在魁北克省南部的许多小城市,地下水被用作
农业是饮用水的主要来源,也是人类的一个重要部门
当地经济(MENV,2003年)。因此,评估
农业压力对农业的影响
提高地下水水质
在靠近工厂的地方进行操作

Since the new Groundwater Catchment Regulation in 2002 was published
in the Province of Quebec, it is now mandatory for municipalities to
describe the wellhead catchment areas to protect their water sources, a
considerable challenge for small municipalities. Utilities with groundwater
sources are thus required to describe the characteristics of their aquifers
and to identify the entire zone of contribution (ZOC) for wells as well as
the groundwater time-of-travel boundaries.
In many small municipalities of southern Quebec that use groundwater as
the primary source of drinking water, agriculture is an important sector for
the local economy (MENV, 2003). It is consequently important to assess
the impact of agricultural pressures on
groundwater quality to promote better
practices in locations close to the
municipal wells. This investigation sets
as a research hypothesis that the
quality of drinking water provided by
municipal wells is under influence of
intensive agricultural practices around
the wells. The study area includes
seven administration regions of the
Province of Quebec, that is about 600
municipal wells. ZOC for wells were
generated based on a local watershed
generation method from a digital
elevation model. This
regional analysis is different from the
approach used in other studies
conducted before because it proposes
the application of a specific spatial unit
(ZOC) for each well instead of using
fixed radius (Tesoriero and Voss, 1997;
Rupert, 2003; Nolan et al., 2002; Rasmussen
and Rouleau, 2003). Includes 10 references, figures.
