We have a recently arrived neighbour that we have not yet met, who has purchased an adjoining property, who appears to have drained a salt water swimming pool into our garden. I looked over the fence and saw a hose running from his now empty salt chlorinated pool up to our fence which is downhill from the pool and the pool was being emptied. I took a couple of photos of the hose and our fence. We have now noticed that nearly every tree along the fence has died about two weeks later. A number of very well established fruit trees have all turned yellow , lost their leaves and died all at the same time plus all the smaller plants in what was an extensive ornamental garden have also gone brown or yellow and are dying. I have shown the leaves to several nurseries who agree they have symptoms of extreme salt damage. I have contacted my insurance company who says we are not insured for damage to trees from a neighbours intentional emptying of a pool into our block. I spoke to the contractor working on the pool and he has denied that it contained salt ( and they are just emptying a bag of salt back into the pool now)!! Who do I see about getting any restitution for this, and preventing it again in the future, as to remove and replace the dead trees would be many thousands of dollars work, plus the soil may have been irretrievably damaged for future planting. Any ideas? Thanks....Owlo
