The Water Quality Association is calling attention to the growing problem of counterfeit water filters by joining forces with the National Intellectual Property Rights Coordination Center (IPR Center). The only way to know if you have high levels of manganese in your drinking water is to have your water tested. It can form compounds with the bicarbonates, sulphates and silicates present at the same time and also with some types of OM (humic and fulvic acids). Food is a significant source of exposure, but bioavailability (meaning the amount that your body absorbs) is greater from drinking water. If you are experiencing unpleasant metallic tastes, rust particles, staining on the bath and sink and other plumbing fixtures, or red water and rotten egg smelling odours, the chances are that you water may have iron, manganese or hydrogen sulphide problems. Drinking water also contains small amounts of manganese at concentrations of 1 to 100 mcg/L [ 5 ]. Some research suggests that exposure to the element via drinking water could cause lower IQ in children and even changed behaviors. Manganese (Mn) is an element found in air, food, soil, consumer products and drinking water. “We knew that manganese had potential to be a concern in Wisconsin because of it being found in the rocks in the ground that we get our water from,” he says. Areas with mining or manganese storage can get it throughout the local area as dust spreads on surfaces or into water. Although manganese and iron are common and naturally occurring, they can cause various problems when found in a drinking water supply. Manganese is considered to be an essential Yet, in general, there are higher concentrations of the mineral in standing water than groundwater.

If you are experiencing black stains on your shower, toilet, plumbing fixtures, or laundry, it is likely you have manganese in your drinking water and it is recommended you have your water tested. The EPA has set a SMCL for manganese of 0.05 mg/L in order to protect against black staining and bitter metallic-tasting water. In surface water, manganese occurs in particulate, colloidal, organic and dissolved forms. Some research suggests that exposure to the element via drinking water could cause lower IQ in children and even changed behaviors. However, exposure to high levels in drinking water pose a health risk to sensitive groups. When manganese is present in water, it … The filter influent total manganese concentration ranged from 0.018 to 0.071 mg/L. Manganese can cause adverse health effects when concentrations exceed the Lifetime Health Advisory Level of 0.3 parts per million. Elevated manganese concentrations can occur in municipal water as well as water from private wells. Studies show that the presence of high levels of manganese in drinking water is linked to reduced intelligence quotients and intellectual impairment in children. In groundwater and some lakes and reservoirs, levels of manganese can be higher depending on water chemistry and due to industrial discharges. Fax: 630-505-9637. If water collected from the well or spring is initially clear but then forms orange-brown or black solid particles over time, the iron and manganese are dissolved in the water. Intellectual impairment in school-age children exposed to manganese from drinking water. [Bouchard MF, Sauvé S, Barbeau B, Legrand M, Brodeur M, Bouffard T, et al. Manganese often results in a dense black stain or solid. Public water systems may test their water for manganese, but they are not required to.
