Tasman District Council have identified “a number of houses” in the Tākaka township that could potentially have contaminated bore water caused by the run-off from firefighting at the ITM building site on January 11.
The fire destroyed Tākaka’s ITM hardware supplies store, with 13 fire trucks battling the blaze at its peak.
At the time of the fire, the Tasman District Council expressed concern that outlet fire “may have led to the discharge” of multiple chemicals into the Motupipi waterway due to run-off.
Tākaka residents and businesses use private bores for their water supply and the council previously confirmed run-off had been confined to one drain of Motupipi St, where it would be extracted.
In an update this morning the Tasman District Council said it has identified “a number of houses,” highlighted in the yellow circle on the map below, that have bore water which is potentially contaminated by run off from firefighting.
The people who occupy those homes have been contacted, council said.
Council also said it received back testing results for other chemicals such as benzene, toluene, ethylbenzene, and xylenes (BTEX).
“The result indicates that there is no BTEX contamination of the water samples taken in the Motupipi Street area,” a statement said.
The statement said based on the information provided and the test results received so far, the risk of the bore being contaminated is “very low”.
“We are taking a precautionary measure to recommend people not to drink the water until we have received all the test results.”
The council said it has undertaken more dye tests and if residents see any pink or red dye or notice any discolouration or odour from their water, to contact council immediately.
It said the other test results will take a longer to process, but it’s hoped all results will be in by Monday next week.
