“…Higher adsorption ability were found for longer chain PFASs compared to short chain PFASs by GAC in plant E (Table 2 and Table S5), this can be explained by the increased K oc values with increasing carbon chain length . Other processes such as sand filtration had no effect in removing PFASs in the present study, which is in agreement with other studies (Takagi et al, 2008;Rumsby et al, 2009;Eschauzier et al, 2012).…”

Water is life, but getting safe water is a question of scarcity. In addition, water sources are being affected by extreme weather and climatic events creating pressure on quality of and access to fresh water. Therefore, it is urgent to know what are the easiest and well-managed ways of ensuring drinking water for everyone, how does the social structure influence the water management at community level. This study explores the importance and influence of societal structure in drinking water management. Results show that cconflict arises during the collection of water between the households and within the household and it has impact on the social connectedness and responsibilities of the community people. Initiatives should also be taken, so that the community management process ensure the equality and equity of access to drinking water as a basic human right.

“…Senthilkumar et al (2007) detected PFOA and PFOS concentrations of 7.9-11 ng l −1 and less than 5.2-10 ng l −1 , respectively, in water samples from the Kyoto River. Takagi et al (2008) monitored raw and tap water from 14 Osaka drinking water treatment plants in summer and winter. PFOS and PFOA were detected in all raw water samples at concentrations ranging from 0.26-22 ng l −1 to 5.2-92 ng l −1 , Atkinson et al (2008) respectively.…”

Perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) are chemicals that have been used for many years as surfactants in a variety of industrial and consumer products. Owing to their persistent, bioaccumulative and toxic (PBT) characteristics, PFOS has been phased out by its principal producer and the use of PFOA has been reduced. This PBT potential and a number of pollution incidents have led in recent years to an increase in studies surveying the concentrations of PFOS and PFOA in environmental waters worldwide. This paper reviews the results of these studies, as well as the monitoring that was conducted after the pollution incidents. The results of surveys suggest that PFOS and PFOA are found in environmental waters worldwide at low levels. In general, these levels are below health-based values set by international authoritative bodies for drinking water. There have been limited measurements of these chemicals in drinking water, but again these are below health-based values, except in some cases following pollution incidents. Monitoring studies suggested that where PFOS and PFOA were detected, they were at similar levels in both source and drinking water, suggesting that drinking water treatment does not remove these chemicals. However, new data show that PFOS and PFOA are effectively removed by granular activated carbon absorbers in practice. Further research is required on the newer perfluorinated chemicals that appear to be safer, but their degradation products have not as yet been fully studied.
