Manganese

GENERAL INFORMATION
Manganese is naturally occurring in many surface and ground water sources and in soils that may erode into these waters. However, human activities are also responsible for much of the manganese contamination in water in some areas.

HEALTH EFFECTS
People with long-term exposure to manganese at levels above the U.S. EPA established Health Advisory Level for long term consumption of 300 ug/L (300 ppb) may develop central nervous system (CNS) problems which look like Parkinson's disease. This syndrome is called "manganism".

Standard value 1: 
300.00
Standard units 1: 
ug/L
Input units: 
ug/L
Contaminant group: 
Inorganic trace constituent
Action is recommended 1: 

U.S. EPA HEALTH ADVISORY LEVEL FOR LONG TERM CONSUMPTION - ACTION IS RECOMMENDED
Manganese levels were detected in your water sample which exceed the U.S. EPA Health Advisory level for Long Term Consumption.

Action is optional 1: 

ACTION IS OPTIONAL
Manganese levels were detected in your water sample were below the U.S. EPA Health Advisory Level for long term consumption; however, it may still exceed the secondary maximum contaminant level (SMCL) which is established at a lower value to reduce asthetic issues manganese may cause such as odor, taste, staining, and/or sediment.

Standard value 2: 
50.00
Standard units 2: 
ug/L
Standard type 2: 
SMCL
Action is recommended 2: 

SMCL ADVISORY - ACTION IS OPTIONAL

Manganese levels were detected in your water sample which exceed the secondary maximum contaminant level (SMCL).

Action is optional 2: 

ACTION IS OPTIONAL

Manganese levels were detected in your water sample below the secondary maximum contaminant level (SMCL).

Typical range in Ohio: 
12 _ 300
Range qualifier: 
higher values in eastern Ohio aquifers
Major sources in drinking water: 
Erosion of earth materials
Treatment options: 

TREATMENT OPTIONS
The most effective way to remove the naturally occurring metals found in your private drinking water is to use a cation-exchange water softener system.
