(1)Where it appears to a river purification authority that any poisonous, noxious or polluting matter or any solid waste matter is likely to enter, or is or was present in, any controlled waters F2. . . , the authority may carry out F2. . . such operations as it considers appropriate—
(a)in a case where the matter appears likely to enter such waters, for the purpose of preventing it from doing so; and
(b)in a case where the matter appears to be or to have been present in such waters, for the purpose of removing or disposing of the matter or of remedying or mitigating any pollution caused by its presence in the waters or of restoring the waters (including the fauna and flora dependent on the aquatic environment of the waters), so far as it is reasonably practicable to do so, to the state in which they were immediately before the matter became present in the waters;

(2)Where a river purification authority carries out any operations in pursuance of this section the authority shall, subject to the following subsection, be entitled to recover the costs of doing so from any persons who caused or knowingly permitted the matter in question to be present at the place from which it was likely in the opinion of the authority to enter the controlled waters or, as the case may be, to be present in the controlled waters.
(3)No such costs shall be payable by a person—
(a)in so far as he satisfies the court in which it is sought to recover the costs that the costs were incurred unnecessarily; or
(b)for any operations in respect of water from an abandoned mine which that person permitted to reach such a place as is mentioned in the preceding subsection or to enter the controlled waters.
