\ndesigned for renovating potable water pipelines. Tests were performed in line with European standards PN-EN 12873-1,
\nPN-EN 14395-1, and PN-EN 16421. The research examined metal, organic compound, and primary aromatic amine
\nmigration, along with organoleptic and microbiological water quality after contact with the coating. No regulatory limits
\nwere exceeded, and PAAs were below the detection threshold of 0.001 mg\/L. These results demonstrate that
\nCOVERLAN does not adversely impact drinking water quality and is safe for use in internal pipeline rehabilitation.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[5128,5126,5129,5125,5124,5127],"tematyka":[387],"class_list":["post-24270","artykul","type-artykul","status-publish","hentry","tag-biofilm-propensity","tag-drinking-water-contact-materials","tag-in-situ-pipe-rehabilitation","tag-polyurea-composite","tag-spray-applied-lining","tag-substance-migration","tematyka-water-supply-and-sewage-system","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["ARTUR PRZYBECKI","IZABELA KRUSZELNICKA","DOBROCHNA GINTER-KRAMARCZYK","MARCIN MOTYLSKI"],"ptb_artykul_text_2":"10.36119\/15.2026.1.7","ptb_artykul_numer_miesi_cznika":"1\/2026 Instal pp.53-57","ptb_artykul_info_autor":"Artur Przybecki https:\/\/orcid.org\/0009-0005-9934-8158 \u2012 Doctoral student, Implementation PhD Programme, Faculty of Environmental Engineering and Energy, Poznan University of Technology, Pozna\u0144, Poland,\r\nIzabela Kruszelnicka https:\/\/orcid.org\/0000-0003-4400-2553 \u2012 Associate Professor at Faculty of Environmental Engineering and Energy,\r\nPoznan University of Technology, Pozna\u0144, Poland\r\nDobrochna Ginter-Kramarczyk https:\/\/orcid.org\/0000-0001-6588-4546 \u2012 Associate Professor at Faculty of Environmental Engineering and Energy, Poznan University of Technology, Pozna\u0144, Poland Marcin Motylski \u2012 R&D Department, TERLAN Sp. z o.o., Pozna\u0144, Poland.
