About the water supply in Mijas
Mijas' tap water is certified safe to drink, with an overall quality score of 9.4/10. The main concern is trihalomethanes, which affect 11 of the 17 networks, potentially impacting taste and comfort. Other issues like lead and hardness are present but only in a few networks, so most residents can enjoy high-quality water daily.
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 year are included — older data is excluded to keep scores current.

🛡️ Trihalomethanes (THMs)
Category: Safety · Legal limit: 100 µg/L
2.2/10Needs attention
78 µg/L — 78% 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. Relatively high — still legal, but close to the limit.

💎 Water hardness
Category: Hardness · Legal limit: no legal limit
4/10Needs attention
311 mg/L CaCO3 — classified as very 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.
0.8 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.
