Research Interests

​Our studies examine the influence of treatment strategy, distribution, network flushing and temporal variations on the microbial quality of drinking water. The overall goal is to characterize the microbial ecology of drinking water distribution systems under different natural and operational conditions to assess biological stability and enhance our understanding of a “healthy” water system. Studies are performed on bulk water samples from raw source, during treatment and then during transport to the consumer, in both Saudi Arabia and The Netherlands.
