Free blood tests will be rolled out today in two east Otago towns to determine whether lead in the water supply will have any chronic effects.
Elevated lead levels in Waikouaiti and Karitāne were first detected almost six months ago, with one result registering nearly 40-times the acceptable level.
A no-drink order was only issued last week after many gaffes, including a council email containing crucial details unopened for weeks.
The source of the contamination is still unknown.
