A district may sue and recover the amount of any district expenditures under Section 60224 from the person or persons responsible for the contaminants causing the expenditures. In proceeding under any state or federal law, a district may recover those expenses from responsible persons and governmental insurance funds. In any action the district, if successful, may recover reasonable attorney’s fees and court costs, as determined by the court. The right or power to recover damages shall not be deemed an adequate remedy at law precluding use of injunctive relief under this section or any other provision of this division or any other statute. In any action for injunctive relief relating to contaminants, no bond shall be required of a district as a condition to granting a preliminary injunction.
