Drinking water contaminants from epoxy resin-coated pipes: A field study
Popis výsledku v původním jazyce
Rehabilitation of aged drinking water pipes is an extensive renovation and increasingly topical in many European cities. A commonly used polymer is epoxy resin consisting of monomer bisphenol A (BPA). Leaching of BPA from epoxy lining to drinking water has been a concern among public and authorities. Currently epoxy lining is not recommended in some countries. BPA leaching has been demonstrated in laboratory studies but the behavior and ageing process of epoxy lining in situ is not well known. In this study 6 locations with different age epoxy linings of drinking water pipes done using two distinct technologies were studied. While bisphenol F, 4-nnonylphenol, and 4-t-octylphenol were rarely found and in trace concentrations, BPA was detected in majority of samples. The influence of ageing of epoxy lining on BPA leaching on could be shown in case of LSE technology: locations with 8-9 years old lining leached 4-20-fold more BPA compared to a location with 2-year-old lining.
