The objective of this study was to evaluate the long-term effects of applying municipal wastewater after primary treatment to the land using the rapid infiltration technique. This was accomplished by analyzing groundwater quality and soil chemistry at a site with a long operating history. Primary municipal effluent has been applied continuously to rapid infiltration basins at Hollister, California, for more than 30 years. Infiltration rates were determined, subsurface hydrology was logged, and water table response to wastewater application was monitored. A sampling and analysis program covering a 1 year period included samples from (1) primary effluent, (2) onsite and control site soil profiles, (3) groundwater at the site and upgradient and downgradient of groundwater movement from the site.
