Protecting surface water through groundwater sampling: Building capacity to characterize hazard at legacy industrial sites

加拿大的城市和农村景观面临着解决工业遗产的挑战， 活动我们在这些地点开展活动的最大障碍是受到污染的土壤和水。这 污染会威胁环境和人类健康。这是进一步复杂的， 在这些环境中发现的污染物分布的复杂性。很少有一个单一的驱动程序， 不利影响，这也意味着可能有一套敏感的受体。我所从事的工作 协助省际合作有限公司（IPCO）开始更好地了解生态危害 与他们关心的温尼伯，马尼托巴的遗产地有关。我知道这个网站有一些连接 地表水，但这是不好的特点，在这个时候。通过检查地下水的反应 在一套水生生物（初级生产者和无脊椎动物）的采样，我将能够使 关于地表沃茨响应的保守预测。同时，我也将考察一部小说的效用 反应，即释放的节肢动物蜕皮酶壳二糖酶作为一种敏感和更迅速的 可能的毒性作用指标。该方法应有助于指导其他受污染的 加拿大各地的网站，从而更及时，更有效的清理和补救。

The Canadian landscape, both urban and rural, faces the challenge of addressing the legacy of industrial activity. The greatest hurdles from our activities on these sites are contaminated soil and water. This contamination can threaten both the environment as well as human health. This is further compounded by the complexity of the contaminant profiles found in these environments. Rarely is there a single driver of possible adverse impacts, which also means there is likely a suite of sensitive receptors. The work I will undertake will assist Interprovincial Cooperative Limited (IPCO) to begin to better understand the ecological hazards associated with a legacy site of concern for them in Winnipeg, Manitoba. I know the site has some connectivity to surface water, but this is poorly characterized at this time. By examining responses from groundwater sampling in a suite of aquatic organisms (primary producers and invertebrates), I will be able to make conservative predictions about responses in surface waters. As well, I will examine the utility of a novel response, namely the release of the arthropod moulting enzyme chitobiase as a sensitive and more rapid indicator of possible toxic effects. The approach should help guide hazard assessment at other contaminated sites across Canada, resulting in more timely and effective clean-up and remediation.
