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 significant concern, scoring 0/10 in 2 of the 3 networks. This may affect the taste and comfort of the water, but overall, it remains safe for daily use, including drinking and cooking.

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.
