Ragersville Elementary is a public water system and is responsible for providing drinking water that meets state and federal standards. Drinking water samples for lead were collected throughout the building on 9-12-23. Our 90th percentile value for lead did not exceed the EPA action level, therefore no further actions are being taken other than to inform parents and guardians that testing results are available upon request in the school office.
DRINKING WATER NOTICE
MANGANESE IS PRESENT IN RAGERSVILLE ELEMENTARY SCHOOL WATER SYSTEM
DO NOT GIVE THE WATER TO INFANTS UNDER 6 MONTHS OLD OR USE TO MAKE INFANT FORMULA OR JUICE
Our water system has exceeded the secondary maximum contaminant level (SMCL) for manganese and in September, October and November 2022 exceeded the USEPA 10-Day Health Advisory for infants under 6 months AND Lifetime Health Advisory for all individuals for manganese. The samples collected in October 2022 showed manganese levels between 0.09 and 0.877 mg/L, with an averaged exceedance determination level of 0.349 mg/L.
The SMCL for manganese is 0.05 mg/L.
The USEPA HAL for manganese is
term period) for infants younger than 6 months: 0.3 mg/L
What health effects are associated with exposure to elevated levels of manganese?
Manganese (Mn) is an essential element for humans and is required for growth, development, and maintenance of health. Many adults consume up to 10mg/day of manganese in diet alone. While low levels of manganese in the diet are important for good health, studies have indicated that life-time exposures of the chemical above the 0.3 mg/L HAL may lead to adverse neurological effects. Several studies have indicated an association between elevated levels of manganese and behavior and neurological effects. Therefore, as a precaution, it is prudent to limit manganese levels in order to protect sensitive populations. The SMCL 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.

What should I do?
FOR INFANTS less than 6 MONTHS, use an alternative (e.g. bottled) water supply for any consumption, including preparation of formula. FOR ALL OTHER INDIVIDUALS no immediate action is necessary; the Ragersville Elementary School is taking steps to correct the problem quickly.
Do not boil the water. Boiling, freezing, or letting water stand does not reduce manganese levels.
What is being done?
The Ragersville Elementary School is taking the necessary steps to correct the problem as soon as possible.
