We have installed a chemical injection system that will add a poly/ortho phosphate blend to the water that will bind manganese into a soluble state before other treatment chemicals reduce its solubility. The system is expected to go online shortly.
The Massachusetts Department of Environmental Protection (DEP) is in the process of inspecting the sequestrant treatment system. They will return on 11/8 to check the pump pacing systems, pipe labeling and finalize the sampling and testing plan.
November 8th Update: DEP completed the inspection and will issue a letter of approval at which point the system will be put into operation.
November 14th Update: We received written approval from DEP and started adding the sequestrant to the water this morning. The dose will be gradually increased over the next 4 weeks until the recommended dose is reached.
November 23rd Update: The dose was increased to 50% of the goal dose on Monday, November 21st.
November 28th Update: The dose was increased to 75% of the goal.
December 5th Update: The sequestrant is now at the recommended dose.
