MSc Students Visit Swords STW

Francis O'Hagan and the MSc
students examining the final effluent
The students of the MSc course in Environmental Science were given VIP treatment when they visited Swords Sewage Treatment Works operated by Fingal County Council.  We were shown around by plant supervisor Mr Francis O’Hagan who gave a very useful insight into the management and operation of a modern wastewater treatment plant. The incredibly low odour at the plant coupled with an excellent final effluent is a huge credit to all the staff of this local authority run plant.

Perchlorate Standard for US Drinking Water

Perchlorate in drinking water is known to suppress thyroid function by inhibiting uptake of iodide and its subsequent ability to produce hormones that are critical to development. Children and new born are particularly at risk. However, the exact safe dose of this compound is unknown. Link Link  In 2002 the US EPA suggested a limit of 1 ppb should be set, but in 2008 the Government decided not to regulate the compound but recommended drinking water concentrations should not exceed 15 ppb.

The US EPA has  now decided to regulate perchlorate under the Safe Drinking Water Act . Perclolrates are used to produce rocket fuel, fireworks and explosives, not activities associated with Ireland. However, they are also found in bleach, in some fertilizers and in nature making them universal. In the US it is estimated that between 5 to 17 million people may be exposed to perchlorate contaminated water with 153 supplies known to be contaminated. A standard is not expected to be set for at least 18-24 months. Link
