New technology could help dairy farms solve pollution issues

Out on the Columbia Basin, a system of worm feces, wood chips and river rocks could spell one solution to the vexing issue of nitrate pollution and greenhouse gases.

To deal with nitrate-laden waste water generated by some 7,000 milk cows, the Royal Dairy outside Othello commissioned a Chilean-based company to build what is the largest treatment facility of its kind in the world.

Whether the system can, or should be, widely adopted by dairies remains to be seen. But in Yakima County, where dairy cows outnumber people, and in other places with mega-sized dairies, the technology is being watched carefully.
