(ii)any rock or stratum containing or likely to contain water (whether dispersed or in natural cavities),
(iii)any peat, moss, sand, gravel, silt or other material that flows or is likely to flow when wet; and
(b)take such steps as may be necessary for the purpose of substantiating any such information which comes into their possession (whether in consequence of the discharge of the duty imposed on them by the foregoing sub-paragraph or not).
