(SD)-Still No Sign Of Keystone Spill In Water
PIERRE, S.D. (AP) - An environmental science manager in the South Dakota Dept of Environment and Natural Resources says testing of water from a drainage ditch next to TransCanada's Keystone pipeline's 210,000-gallon oil spill in the northeast corner of the state found no sign of oil.
Brian Walsh says there were worries about downstream pollution because the ditch in Marshall County appears to flow into a creek, but the lack of oil in the ditch water means cleanup crews can skip that downstream area.
On Tuesday, TransCanada vice president Erik Tatarchuck told the Marshall County Commissioners he believes the leak was "sudden and immediate" not a slow and steady one, which leads him to conclude it's unlikely oil leaked long enough to soak into the ground.
Tatarchuck also says the section of the pipeline where the leak occurred was about 4' underground and is being cut out and sent to the federal Pipeline and Hazardous Materials Safety Administration for analysis to hopefully determine what caused the leak.
TransCanada says that more than 16,000 gallons of oil had been removed from the spill area as of Tuesday with 163 people working on cleanup and assessment.
