"Rainwater" is in quotes in the title because this sample was taken from a roof via the downpipes!! I have made a comment about the level of strontium measured - 0.0084g/m^3 is about 1/1000th the mean seawater concentration reported on wiki of about 8mg/l - so they must be very pleased to have such a low level. (I actualy made 2 - I got the units wrong in my first comment and corrected them in my 2nd) I don't expect my comment to be published because they routinely disappear without trace and I have had a couple of disparaging comments mae about me by the site owner - whereas Ross Marsden seems to get prerferential treatment as the pet ddebunker that they all love to hate! But apart from all that - is is discouraging to see such poor collection practices still being used. The poster says they have collected more water in a clean glass jar - it will be interesting to see if there is any difference - this area of New Zealand, along with most of the rest of the country, has just come out of a 2-3 month dry spell and drought.
