About the water supply in Mijas

Mijas' tap water is certified safe to drink, with an overall quality score of 9.4/10. However, some networks have issues with free chlorine and trihalomethanes, which can affect taste and comfort. Specifically, 3 of the 17 networks show high free chlorine levels, and 10 networks have elevated trihalomethanes. It's important to note that these concerns do not affect all networks, so many residents can enjoy clean and safe drinking water.

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.

⚠ Parameters scoring below 8 — explained

👅 Chlorine taste/smell
Category: Taste · Legal limit: 0.2–1.0 mg/L required
2/10 Needs attention
0.9 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.

🛡️ Trihalomethanes (THMs)
Category: Safety · Legal limit: 100 µg/L
2.2/10 Needs 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.
