<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>My
understanding is the roots will likely have been killed by the effects of the
gas on the soil microbes. I'm not a scientist, but usually there is easier
movement of gas/air along the interface between the soil and roots as there is
usually some movement which would prevent a tight seal. This along with soil
contraction when there are drought conditions would open the soil up for
further movement.</span></font> <br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>Suggest
determining the state of the buds and prepare a valuation for the tree, wait
till next Spring and decide on its fate and subsequent Gas Company
responsibility for the damages, if it does not leaf out. Tree Ownership will
determine who is to pursue the Gas Company.</span></font> <br>

<font size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'>I
received a request for service from a resident here in the City of <st1:City
w:st="on"><st1:place w:st="on">Langley</st1:place></st1:City>. There is an A.
platanoides in his front yard approx 30 years of age and in good health…or it
was.</span></font> <br>
<font size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'>He
says it defoliated approximately two months ago. Last night he called the Natural
gas company as he and his neighbors had evidence of a gas leak in his front
yard. They dug up and repaired the leak. He figures this leak may have been on
going for a couple of months, as they smelt gas of and on over that period. The
soil is going to be removed (just the stuff they excavated) and replaced. When
I arrived the smell was incredible…so much so that I thought it was still
leaking but it was coming from the contaminated soil. I understand that the
natural gas will deplete the soil of oxygen. The actual leak and excavation
was/is approximately 8 meters from the trunk and just outside of the drip line.
My question is what effects will this have on the long term health of the tree?
I am going to investigate into the health of the tree to the best of my
knowledge later in the week but was looking for some insight on this situation.
Any help would be greatly appreciated.</span></font> <br>
