Parma Sostenibile is hosting the Water Blitz, a citizen-science event that invites residents to become “scientists for a day.” After a short training, participants use simple testing kits to check water quality at sites across the city, and their results feed into Freshwater Watch Parma, a monitoring project that runs through 2027 with support from local groups like Legambiente, WWF Parma and the regional parks.
