  Please Enter Known Information:         Treatment System Capacity = gpm     Opinion of Probable Costs (2012):      
                 
  Cr(VI) MCL Being Targeted:       Please Answer the following Questions with Yes or No:              
  Cr(VI) MCL =   µg/L           Capital Cost ($M): Lower End   Upper End  
  Target % of MCL in Treated Water =   %   Question 1:       SBA Treatment = –  
            The Regenerable Ion-Exchange Process (SBA) may generate a Salt Brine that     WBA Treatment = –  
  Well Information:               RCF Treatment = –  
  Well Capacity =   gpm   this Brine to an onsite sewer without treatment? (Yes/No)              
  Well % Utilization =   %             Annual O&M Cost ($/yr): Lower End   Upper End  
            Question 2:         SBA Treatment = –  
  Water Quality Information:         If the answer to Question 1 is "Yes", skip this question and go to Question 3.     WBA Treatment = –  
  Raw Water Cr(VI) =   µg/L   If the answer to Question 1 is "No", can you discharge the waste brine to an onsite     RCF Treatment = –  
  Raw Water pH =       sewer if the Chromium is removed first from the brine? (Yes/No)            
  Raw Water Alkalinity =   mg/L CaCO3             Total Annualized Cost ($/yr): Lower End   Upper End  
  Raw Water Conductivity =   µS/cm   Question 3:         SBA Treatment = –  
  Raw Water Uranium =   µg/L       WBA Treatment = –  
  Raw Water Nitrate =   mg/L NO3         RCF Treatment = –  
  Raw Water Sulfate =   mg/L   this waste washwater to an onsite sewer without treatment? (Yes/No)            
                      Total Water Cost ($/AF): Lower End   Upper End  
  Capital Financing Terms:         Question 4:         SBA Treatment = –  
  Capital Amortization Period =   years   Is your well located in California? (Yes/No)       WBA Treatment = –  
  Amortization Interest Rate =   %             RCF Treatment = –
