More must be urgently done to protect Switzerland’s drinking water, according the Swiss water and gas industry association (SSIGE). One fifth of drinking water samples analysed by the national underground water testing organisation (NAQUA), contained levels of pesticides and nitrates above acceptable levels. And 30% of measurement points, contained very high levels. The highest concentrations were found in underground water, which supplies 80% of Swiss drinking water, mainly in areas with intensive agriculture. The phenomenon is driven by urban development and intensive use of pesticides in agriculture, estimated at around 2,000 tonnes per year, according to NAQUA. SSIGE is calling for a ban on pesticide use in areas that could affect water. Currently only 60% of underground water zones are designated as protected areas. NAQUA’s report shows that the farming sector needs to work hard to avoid polluting water ways. Suggested improvements include mechanical weeding and choosing more weed-resistant plants.
