What is manganese?
It is a mineral that is naturally-occurring in water that has no associated health risk at low levels.

Why does manganese cause discoloration in the water distribution system?
Manganese not removed in the treatment process tends to settle out in the water mains. When sudden flow and velocity changes are experienced in the water mains, manganese can get stirred up, causing discoloration. These changes are typically created when there are water main breaks or when fire hydrants are used either by the local fire company or by unauthorized users.

What is United Water doing to remedy this?
The company is aggressively working on resolving this problem. We are analyzing the treatment process to ensure optimal manganese removal. As a result of this ongoing process, we have altered treatment techniques, which have had a significant impact on resolving the sporadic manganese problem experienced by customers. The company has also hired a part time employee to take additional samples and perform a number of tests. When necessary, we flush fire hydrants in an effort to remove the discoloration from affected mains that have been identified through customer calls. The company, in cooperation with local officials, is also launching an awareness initiative to curb the illegal use of fire hydrants, as well as installing anti-tampering devices on critical hydrants.

What can customers do to remedy the discoloration?
Most customers should be able to clear the discoloration by running their water. If desired results are not achieved after doing this, call the United Water Customer Service Department at 888.299.8972 or 564.3662.
