Reply from Jean McCluskey:
The point here is that WHO guideline is 50mg/l - how worried do we need to be about 55mg/l - where is the important threshold for nitrates in becoming a danger? For what period of time is 55mg/l okay for? If it increases, when would we really need to cut off the water - at how many mg/l do we really need to get worried?
