We have seen this trend where nitrates are in water. This is not a once-off test. This is not like going out and taking a water sample and testing it in a laboratory and saying, "There is a high level of nitrates here." We have seen this trend over the years and we can correlate those trends back to activities that happened in the catchment and contributed to the water quality. That is essentially what EPA reports have been saying for the past 25 years or so.
