Heathcote River pale blue, due to ink spill
Media advisory : Heathcote River pale blue, due to ink spill
Environment Canterbury's Pollution Hotline staff are investigating a spill of around 40 litres of blue ink into the Heathcote River, Christchurch, from Mainstream Freight Group near Parkhouse Rd industrial zone today. The spill occurred around 7pm last night but the ink did not make its way into the river until early today.
Reports suggest that the ink spilled from two 20-litre pails at the freighting firm. How the ink escaped the business's sump/spill storage system and got into the stormwater system leading to the river is still being investigated.
The first complaints to the Pollution Hotline that the Heathcote River was discoloured blue came in this morning after 9 am.
Reports from the public are that fish life in the river appeared so far to be unaffected. Pollution Hotline investigations with industry sources indicate that the ink may be inert, soluble in water and not toxic to fish life. The ink has been diluted by the amount of water in the river due to rainfall.
