Denitrification in‐situ of groundwaters with solid carbon matter
Abstract
We propose a denitrification process of in‐situ treatment. The system has a central drilling from which water is partly pumped out and distributed, the other part is sent in reactors filled up with a mixture of straw and maërl and then reinjected in aquiferous through the soil. Five series of experimentation in‐situ have been made. A fall down of the nitrates in aquiferous from 10 to 20 mg.l−1 has been shown very quickly. The water which goes out from reactors contains organic matter, nitrite and micro‐organisms but is completely purified by going through the soil. So, the drilling water presents a chemical and biological quality compatible with drinkability norms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
