About the water supply in Alhaurin-el-Grande

The tap water in Alhaurin-el-Grande is certified safe to drink, with an overall quality score of 8.6/10. However, total pesticides are a concern, scoring 0/10 in 2 of the 3 networks. Additionally, hardness, odour, and taste issues affect all networks, which may impact daily use and enjoyment. Overall, the water is safe, but some users may notice taste and hardness issues.

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.

Category: Safety · Legal limit: 100 µg/L
7.4/10 Good
26 µg/L — 26% 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. Low level — minimal concern.
