“…In agreement with studies by Massa et al (2001), this study notes that evidence from analysis of polluted groundwater waters suggests that EF may be ‘a more reliable indicator of faecal pollution than faecal coliforms in raw water’ (Massa et al 2001). EF displayed a higher survival and was less susceptible to die‐off, dilution or filtration (Bitton et al 1983; Melian et al 1999; Macler & Merkle 2000; Massa et al 2001). Their greater survival at depth in this study suggests that EF may be a more appropriate means of verifying the compliance of the system to the control measure.…”

The principal water target of the Millennium Development Goals (MDG) is to ensure environmental sustainability by halving the proportion of people without access to safe water by 2015. Although great strides have been made in meeting this challenge since the year 2000, the safety of many of these water supplies remains unknown. Acknowledging the weaknesses of current water quality and hydrogeological means of assuring microbial safety, this paper has the objective of developing improved methods for the assessment and management of microbiological water safety based on a ‘risk’ paradigm. This paper provides evidence for the risk assessment of both conventional aquifer pathways and localised (short circuiting) pathways to 25 wells of three well technology types in Mozambique between 2002 and 2005.* Findings from the research outline improve methods of risk assessment and management by demonstrating that (1) the predominant source of contamination was from animal faeces rather than from latrines/septic tanks, (2) short circuiting is a significant risk to shallow groundwater in developing countries, (3) the use of alternative indicator organisms (e.g. enterococci) may improve risk understanding and (4) the World Health Organisation Water Safety Plans are recommended as an appropriate method of risk management.

“…(Zhao et al, 2015). 또한 Strepto-coccus는 대장균과 함께 토양 및 수질오염의 지표 역할을 하는데 (Van Donsel et al, 1967;Kibbey et al, 1978;Massa et al, 2001;Zhao et al, 2015;Al-Taai, 2021) (Banerjee et al, 2018;Mamet et al, 2019). 따라서 특정 미생물이 두 pH 범위 간 유의한 차이로 존재하며 상대풍부도가 높고 미생물 간 상관관계가 높으면 토양 pH에 따른 주요 미생물일 것이라는 가정 하에 SparCC 네트워크 분석을 하였다 (Fig.…”

Soil microorganism is one of the most important factors in evaluating and improving soil quality because they play a crucial role in the soil material circulation. They are closely correlated with soil environmental factors, and in particular, soil pH has a significant impact on the microbial community. This study aimed to examine the relationship between microbial communities and soil pH in orchard soil of the Republic of Korea. Microbial communities of 63 sites with neutral soil pH (pH 6 -7) and 26 sites with acidic soil pH (pH 3 -5) were analyzed targeting 16S rRNA and ITS genes through Illumina Miseq platform. Our analyses showed that bacterial richness and diversity and fungal richness in neutral soil were significantly higher than those in acidic soil (p < 0.001). According to PCoA and PERMANOVA, the microbial communities were significantly different in two soil groups, and ANCOM-BC showed high abundance of 16 bacterial and 15 fungal genera in neutral soil. Lastly, 9 genera, including Terrimonas, Povalibacter and Gp taxa, were identified as hub genera that have a significant impact on other microbial taxa in neutral soil. These results indicated that soil pH is a critical determinant of microbial communities and can serve as an indicator soil quality monitoring and evaluation.

“…Most studies in which both MPN culturing and direct plating were used, have shown a similar result for both methods (e.g. Line et al, 2001;Massa et al, 2001). However, MPN culturing will not detect those target cells that would form microcolonies when plated on a solid medium (Binnerup et al, 1993).…”
