Lead contamination persists in Odolena Voda water supply; Postřižín sample exceeds limit 3x

A water sample from Postřižín measured 28.9 µg/L lead, nearly three times the hygienic limit, extending the non-potability advisory in the Odolena Voda area. The contamination source remains unconfirmed, and the duration of restrictions is uncertain. This poses a public-health risk and strains local water infrastructure.
