Recommended for this suburb

Chlorine in Coochiemudlo Island is 1.1 mg/L — that's high. It's why your tap water smells like a pool.

Chlorine is added on purpose (kills bugs in the pipes), but by the time it reaches your tap it ruins everything you taste. Tea takes on a medicinal edge. Kids turn down water and drink juice or soft drink instead. The usual family fix is bottled water, but a simple carbon filter is the cleaner daily habit. Worse, many filter pitchers go in the fridge and get ignored because they're slow.
