Which risk increased for Roman aqueducts built using travertine?

💡 Explanation

Increased scaling rises because of carbonate precipitation due to prolonged water contact with travertine; mineral dissolution occurs at the surface boundary, therefore, the water's pH increases inducing encrustation issues rather than cleaner water.
