A fuel line has spilt from my fuel tank in my ute and about 50 litres of petrol has gone on the grass and soaked into the soil. This occurred about 6 weeks ago. About 2 weeks ago I noticed our water in our house smelling like fuel. I have dug up the area where the fuel leaked and found the poly water pipe going into our house was directly under the ground in this area. I have dug up about 4 cubic metres of soil in line with the water pipe and removed all the sand in the trench which really smelt like fuel. I have replace that section of poly pipe but the water still stinks first thing in the morning. I have left the garden hoses running for days but when you turn them off, a few hours later the smell comes back. Do you think the smell will eventually go from the rest of the poly in the house in time?

Are you on a municipal water system or do you have a well?
