The report summarizes the results of an investigation of the technical feasibility of removing dissolved nitrogen from subsurface agricultural tile drainage in the San Joaquin Valley of California. The investigation was divided into the general areas of nitrogen removal by biological systems (algae stripping and bacterial denitrification), effect of nitrogen removal on the biostimulatory nature of the drainage water, and the use of desalination (reverse osmosis and electrodialysis) to remove minerals dissolved in the drainage with special interest in nitrate and boron removal.
