Poisoned Lands and the Grasslands Bypass Project
Salt on the ground, San Joaquin Valley
Western San Joaquin Valley water districts and farmers partnered in 1994 to create the Grasslands Bypass Project, which shunts tainted irrigation drainwater around approximately 100,000 acres of land between Firebaugh and Los Banos west of the San Joaquin River. Water tables there are high and contaminated with high levels of salts, selenium, and other trace metals like mercury, boron and arsenic.
As part of the project, the farmers try to reduce the amount of tainted drainage water by reusing it to have the water consumed by salt-tolerant plants. Meanwhile what water that remains is highly concentrated with pollutants, and the farmers hope to get a pilot reverse osmosis treatment plant funded with public funds, and built to process the remaining drainage water.
C-WIN believes there remain serious long-term problems of cost and unproven treatment technology, and that the Grasslands area drainers should be given a two-year deadline by the State Water Board to come up with a solution, otherwise their polluted lands should be retired from irrigated agriculture (dryland farming could still be practiced, as it was as recently as the 1930s).

C-WIN has obtained verification from an expert on selenium's effects on salmon that the Grasslands Bypass Project kills 50 percent of the juvenile salmon and steelhead in the San Joaquin River .
