Anthropogenic activities and climate change can deteriorate the freshwater quality and stress its availability. This stress can, in turn, have an impact on the biostability of drinking water. Up to now, the microbiological quality of drinking water has been maintained through the selection of high-quality water sources allied to the use of disinfectants and the removal of organic carbon. But as freshwater becomes richer in other nutrients, strategies used so far may not suffice to keep a steady and high-quality supply of drinking water in the future. This article readdresses the discussion on drinking water biostability. We need to reframe the concept as a dynamic equilibrium that considers the available nutrients and energy sources (potential for growth) relative to the abundance and composition of the bacterial community (potential to consume the available resources).

从源头到水源保护微生物水质

人为活动和气候变化可能会使淡水质量恶化并加剧其可用性。反过来,这种压力会影响饮用水的生物稳定性。到目前为止,通过选择与使用消毒剂和去除有机碳有关的优质水源,可以保持饮用水的微生物质量。但是,随着淡水中其他营养素的含量增加,迄今为止所采用的策略可能不足以在将来保持稳定,高质量的饮用水供应。本文重新讨论了有关饮用水生物稳定性的讨论。
