Screening municipal wastewater effluent and surface water used for drinking water production for the presence of ampicillin and vancomycin resistant enterococci

The Llobregat is a 156 km long river, which supplies 35% of the Barcelona's drinking water needs from the Sant Joan Despí Water Treatment Plant. Since the establishment of the Salt Mine Works in the Llobregat basin in 1923, a progressive salinization of the water sources has been recorded. The operation of the Brine Collector, as a public work carried out by Aigües de Barcelona (AGBAR), started in 1989; it enabled a very significant improvement in the quality of the surface water used for drinking-water production.

About forty per cent of drinking water in The Netherlands is produced from surface water. Dutch water companies, that have to rely on this source, are dealing with major water quality problems due to the use of herbicides on pavements. Voluntary measures and bans have had only limited effect on the reduction of emissions of herbicides that runoff from pavements into surface water in The Netherlands. The effects on the production of drinking water from surface water should play a role in the authorisation of pesticides. Stricter regulations, including mandatory emission reduction measures and certification, are necessary. The enforcement of existing Dutch surface water pollution laws should solve part of the problem. Due to the international nature of most of the surface water used for drinking water supply, it is necessary that other countries take measures as well. European legislation brings a solution closer if implemented well and seriously enforced. The threat of strict legislation keeps pressure on the transition towards decreasing the dependence on chemicals for weed control on pavements.

Drinking Water Production

Drinking water has to be wholesome and clean, free from chemical and, most of all, microbiological contaminants. The German Landeswasserversorgung (LW), a long distance water supplier, uses surface water and water influenced by surface water as well as groundwater for drinking water production. A combination of several treatment steps including flocculation, sedimentation, ozonation, in-line filtration and, finally, disinfection with chlorine dioxide guarantees a drinking water of perfect quality. Since the water transport through several main and subsidiary pipes of an overall length of about 500 kilometres can take up to four days, the disinfection capacity must be sufficient to prevent bacterial growth. Measurement of the redox potential in addition to measurement of chlorine dioxide concentrations has proved to be a helpful parameter for the surveillance of the disinfection capacity. Many years of experience show that keeping the redox potential above a level of 650 mV guarantees the prevention of bacterial growth and an efficient disinfection.
