The new system of daily water-quality measurements operated by Cowama on Torremolinos beaches has already proved its worth - SUR is reporting that rubbish that appeared in the sea off La Carihuela beach doesn't contain any dangerous matter and probably came from a boat. Even so, the Ayuntamiento has ordered a full investigation.
The system is designed to monitor continuously the water quality, and issue information in cases such as these. Whilst finding the rubbish in the water would be alarming for swimmers, at least those who did so can rest assured there was no health risk.
Visitors can get up-to-date information on a daily basis by using the iBeach app - a first for the Costa del Sol. Benalmádena are working towards joining the scheme for next year - but they'll have to stop people chucking rubbish off the boats first!
