Details:	SUMMARY: Assistance with Equipment modifications DETAILS: Warrenton owns and operates a membrane filtration plant which provides water to approximately 9000 persons including the Cities of Warrenton and Hammond. The system had been experiencing problems with HAA5 levels due to organics in their raw water. ACH has since been added to aid in the removal of these organics. This was successful. The City wishes to move the chemical feed into the new plant (it is currently at the old plant), as well as add a streaming current monitor. Previously provided recommendations for new equipment locations as well as dosing recommendations. We discussed progress of the chemical feed changes. I provided advice on installation issues. ACTION NEEDED: Provide additional equipment installation advice as needed.
