This support has benefited regional communities, and especially smaller utilities, by helping to identify and control risks. NSW Health's support projects have resulted in statistically significant improvements across many elements of drinking water management system implementation. Through this program of support, NSW Health has identified possible infrastructure and operational needs and assessed implementation of drinking water management systems. In parallel, NSW Health has worked to assess the risk from Cryptosporidium in drinking water supplies and to develop a formal audit program. Findings from the NSW Health support program informed the development of two NSW Government programs and the commitment of more than $1 billion to help local water utilities address public health and other critical needs. The introduction of risk-based drinking water management systems has driven incremental improvement in drinking water quality management across the state of NSW.<\/jats:p>","DOI":"10.2166\/wh.2023.125","type":"journal-article","created":{"date-parts":[[2023,7,20]],"date-time":"2023-07-20T13:43:33Z","timestamp":1689860613000},"page":"1098-1109","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":2,"title":["Supporting the implementation of drinking water management systems in New South Wales, Australia"],"prefix":"10.2166","volume":"21","author":[{"given":"Tran T.","family":"Huynh","sequence":"first","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leslie","family":"Jarvis","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wendy","family":"Henderson","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zenah","family":"Bradford-Hartke","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandy","family":"Leask","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine","family":"Gajo","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua","family":"Tickell","sequence":"additional","affiliation":[{"name":"b Local Water Utilities Branch, NSW Department of Planning and Environment, 12 Darcy St, Parramatta, NSW 2124, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3036-1459","authenticated-orcid":false,"given":"Katrina","family":"Wall","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Byleveld","sequence":"additional","affiliation":[{"name":"a Water Unit, Environmental Health Branch, NSW Health, 1 Reserve Road, St Leonards, NSW 2065, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2023,7,20]]},"reference":[{"key":"key-10.2166\/wh.2023.125-1","volume-title":"Australia's Health 2018: In Brief (Full Publication; 18 June 2019 Edition)","author":"Australian Institute of Health and Welfare (AIHW)","year":"2018"},{"key":"key-10.2166\/wh.2023.125-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijheh.2014.12.004"},{"key":"key-10.2166\/wh.2023.125-3","doi-asserted-by":"publisher","DOI":"10.1071\/NB08031"},{"key":"key-10.2166\/wh.2023.125-4","doi-asserted-by":"publisher","DOI":"10.17061\/phrp2621615"},{"key":"key-10.2166\/wh.2023.125-5","volume-title":"Drinking Water Safety Plans","author":"Gagnon","year":"2015"},{"key":"key-10.2166\/wh.2023.125-6","unstructured":"Geoscience Australia. 2023 Area of Australia \u2013 States and Territories.
