If not managed, hydrogen sulphide (H2S) emission from stormwater retention ponds can cause water quality and quantity problems that are detrimental to property values, human health, and watershed health. Several of the hundreds of stormwater retention ponds and constructed wetlands located across the City of Edmonton generate high levels of H2S. Nitrate products applied to these ponds by the City of Edmonton failed to counteract H2S production. Little work has been done to characterize the stormwater retention ponds that produce H2S. The lack of information regarding these ponds has made it difficult to implement effective control strategies for the emission of H2S. Therefore, a study of Edmonton's stormwater chemistry and microbiology might suggest a method to alleviate the problem.

如果不加以管理，雨水蓄水池中的硫化氢（H2S）排放会导致水质和水量问题，对财产价值、人类健康和流域健康有害。位于埃德蒙顿市的数百个雨水滞留池和人工湿地中的几个产生高水平的H2S。埃德蒙顿市向这些池塘施用的硝酸盐产品未能抵消H2S的产生。很少有工作已经做了表征雨水滞留池，产生硫化氢。缺乏关于这些池塘的信息使得难以实施有效的H2S排放控制策略。因此，对埃德蒙顿的雨水化学和微生物学的研究可能会提出一种缓解问题的方法。
