Title: Well 7991-1 Arsenic Removal System
Description: Construction and operation of a 2.88 mgd capacity arsenic removal system and auxillary pipelines on 0.5 acres at existing District Well 7991-1 to reduce arsenic concentrations to meet drinking water requirements. In addition, a 700 cu yd percolation/evaporation pond for well blow-off water would be constructed on the site with connection to underlying tile drains. The treated, nonhazardous brine waste would be hauled for discharge to a nonreclaimable waste pipeline, the Santa Ana Regional Interceptor. The coagulated brine waste would be disposed of properly at a Class I hazardous waste landfill. Construction duration would be 7 weeks.
