Nr 256 (VI) Borehole at Antwerp, april 1945.
British army borehole to obtain washing water.
Abandoned whithout yield test, owing to high
salinity, and tubes withdrawn.
Surface level about 7 m (nota: 2 m??)
Rest water level 8 feet (2.4 m) below surface.

Salinity figures as milligrams of NaC1 per litre.
0.00 - 2.4 m - 32 Probably water Subsequent tests of shallow
2.4 - 3.96 m - 31 used for holes showed a salinity
3.96 - 5.48 m - 51 drilling between 5 - 7 metres of
5.48 - 7.0 m - 30 510 mg NaC1 per litre
10.06 m - 58
11.58 m - 620
11.58 - 13.10 m - 8.700
19.20 m - 10.250
Subsequently a series of shallow holes were sunk, each 24'(7.3 m) deep 4m
apart. Average yield was 300 gals (1.4 m 3) hour each. Water was taken by
screening and sand packing between 8'(2.4 m) and 23'(7.0 m).Diameter 10
inches (25 cms). Salinity 510 mg NaC1/litre. (Numerotatie bijgevoegd door
