N/A
 
Details: SUMMARY: Discuss Lead and Copper (L&C) DETAILS: Jim said he sent the L&C information to HBH last week. When the system tested for DIC they got 28 when we use our tables in the L&C manual I get a DIC of 53. With a number of 53 it shows they need to raise the pH to 7.2-7.8 by using aeration and orthophosphate or blended phosphate. If we go with their DIC of 28 then we would need to raise the pH in 0.3 increments using aeration or caustic or potassium hydroxide. ACTION NEEDED: Meeting with Casey and Betsy nest week to discuss
