“…A study assessing NOM removal in DWTPs in three Nordic capitals found similar removal efficiencies for similar treatment processes (chemical precipitation, sedimentation, filtration and disinfection processes), namely 55% (Oslo), 48% (Stockholm DWTP using the same raw water reservoir as in this study) and 76% (Helsinki). 56…”

“…Organic carbon migration (or leaching) from the material into the water is a main reason why synthetic polymeric materials are relevant for microbial growth in buildings. Drinking water is typically carbon-limited with low concentrations of bioavailable organic carbon [57,58]. As a result, migrating carbon compounds increase the growth potential of a system.…”

The environmental conditions in building plumbing systems differ considerably from the larger distribution system and, as a consequence, uncontrolled changes in the drinking water microbiome through selective growth can occur. In this regard, synthetic polymeric plumbing materials are of particular relevance, since they leach assimilable organic carbon that can be utilized for bacterial growth. Here, we discuss the complexity of building plumbing in relation to microbial ecology, especially in the context of low-quality synthetic polymeric materials (i.e., plastics) and highlight the major knowledge gaps in the field. We furthermore show how knowledge on the interaction between material properties (e.g., carbon migration) and microbiology (e.g., growth rate) allows for the quantification of initial biofilm development in buildings. Hence, research towards a comprehensive understanding of these processes and interactions will enable the implementation of knowledge-based management strategies. We argue that the exclusive use of high-quality materials in new building plumbing systems poses a straightforward strategy towards managing the building plumbing microbiome. This can be achieved through comprehensive material testing and knowledge sharing between all stakeholders including architects, planners, plumbers, material producers, home owners, and scientists.

“…Daily DOC measurements were recorded daily for 7 days. The BDOC fraction was then calculated as the difference between the maximum DOC value and the minimum DOC value (Krzeminski et al, 2019). To determine the overall removal of NOM and efficiency of the various treatment steps, UV-Vis absorbance was measured in the wavelength range of 200-800 nm, and UV 254 data were collected at λ = 254 nm (Aqualog, HORIBA, Jobin Yvon).…”

“…Therefore, DOC reduction is not adequate to identify the specific DOC fractions available for mineralization by heterotrophic bacteria. Knowledge of the nature of the labile fraction available for assimilation by heterotrophic bacteria is necessary for adjusting the treatment protocol to target the problematic fraction and hence induce bacterial die‐off (Krzeminski et al, 2019).…”

Natural organic matter (NOM) influences the quality and treatability of drinking water; therefore, its removal is paramount. A few studies exist on NOM removal in developing countries, and comparative studies are even fewer globally. This study compared the removal efficiencies for bulk NOM and biodegradable organic carbon (BDOC) fractions of drinking water treatment plants in Zimbabwe (Z) and South Africa (S). NOM removal efficiency at the coagulation stage of plant Z and plant S was 11% and 13%, respectively. The fluorescence index (FI) for the raw water feeding plant Z (1.66) indicated a mixture of both microbial and terrestrially derived NOM, whereas for plant S the FI (4.08) showed terrestrially derived NOM. Based on the log-transformed absorbance at the disinfection stage, plant S had a 58% greater opportunity to produce disinfection by-products than plant Z. The BDOC results for plant Z showed humic fractions were the major substrates for bacterial assimilation, whereas the heterotrophic bacteria in plant S were not particularly selective toward DOC fractions. Overall, the plants had comparable NOM removal performances.
