ViK Veliko Tarnovo (Yovkovtsi OOD) lists 2.52 mgeq/L total hardness for Veliko Tarnovo on its laboratory page, which is about 126 mg/L CaCO3. The page is undated, so the 2025 date is inferred from the utility's 2025 annual quality file. The same value is printed for several nearby towns, so it looks like a system-wide figure and not a per-street one. Bulgarian rules list total hardness as a monitored parameter without a limit.

Bulgarian health inspectorates report hardness in mgeq/L (1 mgeq/L = 0.5 mmol/L); the limit is 12 mgeq/L.
