Sec. 8.
(a) The district may conduct any investigation of the quality of the surface and groundwaters within the district that the district determines to be necessary and appropriate to determine whether those waters are contaminated or polluted.(b) The district may expend available funds to perform any investigation investigation, cleanup, abatement, or remedial work required under the circumstances that, in the determination of the board of directors, is required by the magnitude of the endeavor or the urgency
of prompt action needed to prevent, abate, or contain any threatened or existing contamination of, or pollution to, the surface or groundwaters of the district. This action may be taken in default of, or in addition to, remedial work by the person causing the contamination or pollution, or other persons. The district may perform the work itself, by contract, or by or in cooperation with another governmental agency.
(c) If, pursuant to subdivision (b), any contamination or pollution is investigated, cleaned up, or contained, the effects of the contamination or pollution abated, or in the case of threatened contamination or pollution, other necessary remedial action is taken, the person causing or threatening to cause that contamination or pollution shall be liable to the district to the extent of the reasonable costs actually incurred in
investigating, cleaning
up, or containing the contamination or pollution, abating the effects of the contamination or pollution, or taking other remedial action. The amount of those costs, together with court costs and reasonable attorney’s fees, shall be recoverable in a civil action by, and paid to, the district. In this action, the necessity for the investigation, cleanup, containment, abatement, or remedial work, and the reasonableness of the costs incurred therewith, shall be presumed, and the defendant shall have the burden of proving that the work was not necessary, and the costs not reasonable.
(d) The remedies provided under this section are in addition to all other legal or equitable remedies available to the district under statute or common law, including declaratory relief regarding liability for the district’s future
costs.
