Water Notice: Proctorville Water Has Abnormal Levels of Manganese


Proctorville Water Has Levels of 

Manganese Above Drinking Water Standards


Our water system has exceeded the secondary maximum contaminant level (SMCL) for manganese and has recently 08/23/19 exceeded the USEPA 10-Day Health Advisory for infants under 6 months AND lifetime Health Advisory for all individuals for manganese. The sample(s) collected on 08/23/19 show manganese levels at 737 mg/L.

  • The secondary MCL for manganese is 0.05 mg/L
  • Ten Day HAL for children under 6 months (consuming the water regularly for 10 days) AND Lifetime HAL (individuals over 6 months consuming the water regularly for a lifetime): 0.3 mg/L.

What should I do?

FOR INFANTS less than 6 MONTHS, use an alternate (e.g. bottled) water supply for 

any consumption, including preparation of formula. FOR ALL OTHER INDIVIDUALS no immediate action is necessary; the Village is taking steps to correct the problem quickly.

Manganese (Mn) is an essential element for humans, animals, and plants and is required for growth, development, and maintenance of health. While low levels of manganese in the diet are important for good health, studies have indicated that long term oral exposures of the chemical above the 0.03 mg/L HAL may lead to adverse nuerological, or reproductive effects. Several studies have indicated an association between elevated levels of manganese and behavior and neurological effects in children. Therefore, as a precaution, it is prudent to limit manganese levels in drinking water in order to protect sensitive populations (infants and children). The secondary MCL (0.05 mg/L) for manganese is set for aesthetic purposes, as the water could appear black or brown in color. Items that come in contact with the water could be stained black, and the water could have a bitter metallic taste.

If you have specific health concerns, consult your doctor.
