PIERRE - A proposed crude-oil pipeline would pass near some shallow underground water sources in Marshall and Brown counties, an expert says.
The route proposed for a Trans-Canada Keystone Pipeline through South Dakota was altered during planning stages to limit the distance across shallow aquifer areas that the line would travel, Heidi Tillquist said in testimony filed with the state Public Utilities Commission.
