Details: | SUMMARY: Update on Arsenic treatment options DETAILS: I spoke with Pete regarding status update on Arsenic Treatment options ahead of Sept 30 date to submit plan review info to DWP outlined in Bi-Lateral Compliance Agreement. System working with HBH and Crow Water. Current preference is to augment system with adsorber-has less maintenance and would not reconfigure current system which addresses hardness and iron. Dikeside approached adsorbtive media vendor, who was concerned high total organic carbon (TOC) would foul up media. Dikeside to submit TOC after current treatment to see if it is lower and more amenable to technology. Adding ferric chloride to system (which would reconfigure system and require more daily maintenance) or point of use are secondary options for Dikeside. ACTION NEEDED: Dikeside to follow up with lab to forward treated TOC result to vendor, and approach DWP if they wish to contact other systems with experience treating arsenic. |
