Notes

This test was carried out on Tuesday. The previous tests had only been carried out the previous Friday, ie 4 days before. But the Friday test had been carried out after a period of dry weather. Because there had been very heavy rain on the Saturday and some rain on the Sunday, another test was carried out to see if the results would be better because of the extra flow. I was expecting the ammonia to be better, but in fact it was the worst it has been for some time. However, the phosphate was a better result.
