In 2009 the Water Services Corporation laboratory collected 1,217 samples of water being provided for consumption and carried out a total of 19,830 tests on them.
Answering a parliamentary question by Anthony Agius Decelis (PL), Finance Minister Tonio Fenech said such samples were collected regularly from various sources, including towns and villages.
Minister Fenech added that Malta and Gozo were divided into 19 water quality zones, in which water quality from various sources was considered to be uniform.
