A campaign group which wants cleaner seas and rivers is planning another protest against Southern Water this month - because of concerns about high e-coli readings.

SOS Whitstable has been monitoring the levels using kits provided by Southern Water.

The company says it's investing in new technology to reduce storm overflows.

Environment Correspondent Yvette Austin went to watch the testing and spoke to campaigner Catherine Chapman along with Lab councillor Chris Cornell.
