How to read these scores: 10 = perfect, 0 = at or over the legal limit. A score of 0 does not necessarily mean the water is unsafe — it means that specific parameter is at its maximum legal level. The official SINAC certification (APTA / NO APTA) is the authoritative safety indicator. Only readings from the last 6 months are included — older data is excluded to keep scores current.

⚠ Parameters scoring below 8 — explained

👅 Chlorine taste/smell
Category: taste · Legal limit: 0.2–1.0 mg/L required
0/10 Needs attention
1 mg/L. Chlorine is legally required (minimum 0.2 mg/L) to keep water safe as it travels through pipes. High chlorine level — a noticeable taste and smell. Letting water stand in an open glass for a few minutes will reduce it.
Network: PARQUE ANTENA-ESTEPONA-RED PARQUE ANTENA · Value: 1 · Date: 11/02/2026
💎 Water hardness
Category: Hardness · Legal limit: no legal limit
2/10 Needs attention
513 mg/L CaCO3 — classified as extremely hard. Very hard water — significant limescale buildup on appliances. Water softener or filter recommended for kettles and washing machines. Safe to drink but has a mineral taste. There is no legal limit for hardness as it poses no health risk.

🛡️ Trihalomethanes (THMs)
Category: Safety · Legal limit: 100 µg/L
4.7/10 Needs attention
53 µg/L — 53% of the 100 µg/L legal limit. Trihalomethanes form when chlorine (used to disinfect water) reacts with natural organic matter. They are safe at these levels but are a reason some people prefer to filter tap water. Moderate level — within legal limits but noticeable to sensitive people.
