UTV's environmental correspondent Brian Black reports on an issue which continues to be a matter of concern to this day. Back in 1996 alarm bells were ringing over the level of phosphates in Lough Neagh. Fifteen years earlier the lough (the largest body of freshwater in the British Isles) had been on the brink of being decalred a dead lake and matters were heading back in that direction once more.

Brian spoke to a number of experts about the problem of farmers overusing phosphates on their lands which then runs off into rivers and into Lough Neagh. He also speaks to farmer Seamus McWilliams who was making an effort at a more environmentally friendly method of farming.
