Field studies of manganese deposition and release in drinking water distribution systems: Insight into deposit control
TL;DR: Investigation of the deposition and release behaviors of Mn in full-scale DWDS shows that particulate Mn tended to accumulate in DWDS even at concentrations as low as 10 μg/L, and enhanced oxidation and filtration for Mn removal during water treatment processes are proposed.

The occurrence and transformation behaviors of disinfection byproducts in drinking water distribution systems in rural areas of eastern China.
TL;DR: The spatial variability analysis showed that the total concentrations of HAAs and HANs decreased during long hydraulic residence time (HRT) in seven drinking water distribution systems, which could result in reduced mammalian cell cytotoxicity and genotoxicity at consumers' taps.

Occurrence and transport behaviors of perfluoroalkyl acids in drinking water distribution systems
TL;DR: It was calculated that PFOA has a higher partition coefficient than PFBA; this means that the former has a stronger potential to be adsorbed by loose deposits, and the accumulation ability of loose deposits might be associated with the composition of Al, Fe and Si in the loose deposits.

Revealing the changes of bacterial community from water source to consumers tap: A full-scale investigation in eastern city of China
TL;DR: The results showed that different water treatment processes affected the bacterial community structure in different ways, and some microorganisms proliferated and grew in the distribution system, which could lead to turbidity increases in the tap water.

The stability of Fe(III)-As(V) co-precipitate in the presence of ascorbic acid: Effect of pH and Fe/As molar ratio.
TL;DR: The findings of this study implied that parasymplesite and humboldtine as secondary solid products were environmental relevant and mainly responsible for As(V) and Fe(II) immobilization.
