Surveys were carried out in East Java, Indonesia, to determine the nitrate concentrations of (a) household well waters in selected settlements, (b) certain other waters, and (c) selected soil profiles. Nitrate concentrations in the well waters ranged from zero to 304 mg/ L, with marked differences between regions and between wells within a given settlement. The patterns of nitrate concentrations within villages as well as in and around rice fields appear to exclude the application of nitrogen fertilisers to rice fields as a significant cause of the nitrate observed in well water. Of all the nitrate sources considered, the main ones are likely to be food and feed brought from outside into villages, and which, after ingestion, are excreted in a localized way inside them, giving rise to large spatial variation in nitrate concentrations.
