View largeDownload slide View largeDownload slide Close modal The amount of medical waste generated has increased enormously since the COVID-19 outbreak. An incineration process is the main method that is usually used to treat this waste, causing an increase in both medical waste bottom ash (MWBA) and medical waste fly ash (MWFA). In this work, the physical and chemical characteristics of MWFA and

Prevalence and genetic distribution of Legionella spp. in public bath facilities in Kobe City, Japan J. Water Health (IF 2.3) Pub Date : 2023-11-01 Shoko Komatsu, Shinobu Tanaka, Noriko Nakanishi
Legionella is an important waterborne pathogen that causes legionellosis. Public baths are considered the primary cause of legionellosis infection in Japan. We investigated the prevalence and genetic distribution of 338 Legionella spp. isolates from 81 public bath facilities, including 35 hot springs and 46 other facilities, through annual periodic surveillance in Kobe, Japan, from 2016 to 2021.

Water containers and the preferable conditions for laying eggs by Aedes mosquitoes in Maros Regency, South of Sulawesi, Indonesia J. Water Health (IF 2.3) Pub Date : 2023-11-01 Made Agus Nurjana, Yuyun Srikandi, Tri Juni Wijatmiko, Nurul Hidayah, Rina Isnawati, Octaviani Octaviani, Gunawan Gunawan, Samarang Samarang, Meiske Elisabeth Koraang, Hayani Anastasia, Ningsi Ningsi
One of the factors that influence the development of mosquitoes is the water container. This study was performed to determine the relationship between the characteristics of water containers and the preferable conditions for laying eggs by Aedes sp. A single larva method was conducted during March 2019 in 300 houses in two villages (Turikale and Adatongeng) at Maros Regency, Indonesia. In total, 1

When the implementation of water safety plans fail: rethinking the approach to water safety planning following a serious waterborne outbreak and implications for subsequent water sector reforms J. Water Health (IF 2.3) Pub Date : 2023-10-01 Jim Graham, Kathryn Russell, Brent Gilpin
Water suppliers in New Zealand have been preparing the water safety plans (WSPs) since 2005; large drinking water-associated outbreaks of campylobacteriosis occurred in Darfield in 2012 and in Havelock North in 2016. This paper reviews the WSP that was in place for Havelock North, and analyses why it failed to prevent this outbreak. The risk assessment team completing the WSP underestimated the risks

Misjudging drinking water quality risk: Adopting a barrier approach for meaningful risk assessment to address latent risks J. Water Health (IF 2.3) Pub Date : 2023-10-01 Richard Walker
The water quality risk assessment is the foundation for every drinking Water Safety Plan. The need to conform with a ‘Corporate’ risk assessment model commonly dominated by asset management frequency data can cause misjudgement of microbial risk. Well-performed risk assessments should identify potential risks. Risk assessments which place too much emphasis on historical evidence to demonstrate ‘likelihood’
