$364K to clean up toxic soil, water

The Nevada Irrigation District will have to spend $364,000 to dispose of contaminated soil and water that was discovered while replacing a major water pipeline in the Brunswick basin.

On Wednesday, NID directors approved to spend an additional $477,267 on the pipeline project that managers expect to have buttoned up by next week. Up to 76 percent of that money will fund the disposal of soil and groundwater contaminated by previous mine tailings used to fill Lake Olympia decades ago.

“We had to get rid of 200,000 gallons of ground water,” contaminated with arsenic and gasoline derivatives, said Adrian Schneider, project manager.



The water was treated and run through carbon filters then sent through Grass Valley’s wastewater treatment plant. Another 4,000 tons of soil contaminated with chromium and arsenic was trucked to the Ostrom Landfill in Wheatland, Schneider said.

The remainder of the extra costs come from roadwork and miscellaneous items.




Considered a major transmission pipeline spanning less than a mile, it feeds the lower portions of the district and runs beneath the Brunswick Basin and sections of Highway 49. Crews have been digging up roadway since January to replace pipeline damaged by three separate ruptures last year.
