In the summer of 2023, the people of the UK and Ireland were stunned when a foul-smelling green algae bloom blanketed the surface of Lough Neagh – the largest freshwater body on these islands – suffocating aquatic life and signalling an unprecedented environmental disaster.

Troubled Waters is a damning exposé, which uncovers the shocking destruction of the lough, source of almost half of Northern Ireland’s drinking water and a place steeped in historical and cultural significance. Award-winning journalist Tommy Greene delves deep into a gripping tale of greed, corruption, ineptitude and environmental catastrophe that has unfolded in plain sight against a backdrop of governmental instability and systematic cover-ups.

With a cast of characters ranging from aristocratic landowners to locals who have fished the lake for generations, Greene exposes the fierce battle that will determine the future of this once-thriving ecosystem which now teeters on the brink of ecological collapse.
