The air quality in Blenheim was tested yesterday to discover the source of the air pollution in the area.
Marlborough District Council environmental scientist Fleur Tiernan and the National Institute of Water and Atmosphere started testing in Redwoodtown, one of the areas with the highest level of air pollution.
The mobile monitor measured air temperature, wind speed and PM10 [tiny particles which contaminate the air] to get a pattern of where the hot spots were, Ms Tiernan said.
This was the third of four days of testing to collect the initial data, with the results available in about two months.
Last year was one of the worst winters for air pollution in Marlborough, at six times more than the Ministry for the Environment limit. The limit has been exceeded four times already this year.
Picton is being tested today.
Is the region better served by having multiple events over one weekend or spread out throughout the year?Related story: (See story)
