Arsenic water is unlikely' to be dangerous
An immediate ban on drinking tap water was placed on the local national school and 22 houses on the scheme last week, after arsenic levels, which were more than six times higher than the maximum recommended level, were found following routine tests on the water. The arsenic was believed to have come from underlying rocks in the area, and Wexford County Council immediately set about procuring specialist arsenic removal equipment.
When asked to comment on the health issues arising from exposure to the stated levels of arsenic, the HSE said that until a treatment system was put in place, water should not be used for drinking, drinks made with water, preparation, washing or cooking of food, brushing of teeth or making of ice. It can be used for personal hygiene, bathing, flushing toilets, laundry and washing of utensils.
In a statement, the HSE explained that arsenic is a metalloid, which occurs naturally in soil and rocks. Erosion of these can cause arsenic to be released into water sources. Very low levels of arsenic are normally found in drinking water.
Long-term exposure to arsenic via drinking water has been associated with some increased cancer risk but given the levels of arsenic found in this supply, a spokesperson said it is unlikely that any adverse health affects will arise.
There are drinking water guidelines in place that are protective of health, which in this instance have been exceeded,' they added. However, these guidelines are set assuming a lifetime exposure and therefore the level to which consumers have been exposed to date is unlikely to result in any adverse health effects.'
