... compared to densities of these same culturable organisms on biofilm pre-colonized coupons. Results demonstrate that drinking water distribution systems may be vulnerable to the development of potentially pathogenic bacteria in biofilm when lines are initially placed in service. Conclusions...

...Tong Li; Peter M. Huck Drinking water filtration systems should be as robust as possible to consistently provide finished water of high quality to protect public health. The quantification of robustness makes it possible to evaluate the status of a given system. This paper introduces a newly...

...R. Hofmann; R.C. Andrews This note identifies potential side effects of using ammonia to inhibit bromate formation during the ozonation of drinking water, and makes preliminary predictions of their significance. Based on kinetic calculations, it is expected that ammonia would not exert...
