any of the NATMAP products except NATMAP soilscapes.
SOILSERIES leacs provides information on the shrink-swell and corrosivity
of the soil to Fe and Zn. This data set is being used by most major water
companies for the prediction of the corrosion rates on their pipes. It

SHRINK_SWELL
6
Shrink-swell class, Clayden and Hollis (1984, 33-35), Hollis (1991,
unpubl), Jones and Hollis (1996, unpubl)
CORR_FE
4
Corrosivity code for Fe, Jarvis and Hedges (1994). If there is a
* in this field, this indicates that there is likely to be a trace of sulphate present.
If, on further investigation there is no sulphate, the class should be 1 lower.
Conversely, if there is plenty of sulphate, add one to this class.
