(1) In this section: (a) “Private water supply” means a well that is used as a water supply for humans or a well that is constructed by drilling and is used as a water supply for livestock, as defined in s. 95.80 (1) (b), or poultry. (b) “Regulated activity” means an activity for which the department may issue an order under chs. 285 or 289 to 299 or this chapter, if the activity is conducted in violation of chs. 285 or 289 to 299 or this chapter or in violation of licenses, permits or special orders issued or rules promulgated under chs. 285 or 289 to 299 or this chapter. (2) (a) Except as provided under par. (b), if the department finds that a regulated activity has caused a private water supply to become contaminated, polluted or unfit for consumption by humans, livestock or poultry, the department may conduct a hearing on the matter. The department shall conduct a hearing on the matter upon request of the owner or operator of the regulated activity. At the close of the hearing, or at any time if no hearing is held, the department may order the owner or operator of the regulated activity to treat the water to render it fit for consumption by humans, livestock and poultry, repair the private water supply or replace the private water supply and to reimburse the town, village or city for the cost of providing water under sub. (4). (b) If the department finds that a regulated activity caused a private water supply to become contaminated, polluted or unfit for consumption by humans, livestock or poultry, and if the regulated activity is an approved facility, as defined in s. 289.01 (3), the department may conduct a hearing under s. 292.31 (3) (f). If the damage to the private water supply is caused by an occurrence not anticipated in the plan of operation which poses a substantial hazard to public health or welfare, the department may expend moneys in the environmental fund that are available for environmental repair to treat the water to render it drinkable, or to repair or replace the private water supply, and to reimburse the town, village or city for the cost of providing water under sub. (4). If the damage to the private water supply is not caused by an occurrence not anticipated in the plan of operation, if the damage does not pose a substantial hazard to public health or welfare, or if moneys in the environmental fund that may be used for environmental repair are insufficient, the department may order the owner or operator of the regulated activity to treat the water to render it fit for consumption by humans, livestock and poultry, or to repair or replace the private water supply, and to reimburse the town, village or city for the cost of providing water under sub. (4). (3) In any action brought by the department of justice under s. 299.95, if the court finds that a regulated activity owned or operated by the defendant has caused a private water supply to become contaminated, polluted or unfit for consumption by humans, livestock or poultry, the court may order the defendant to treat the water to render it fit for consumption by humans, livestock and poultry, repair the private water supply or replace the private water supply and to reimburse the town, village or city for the cost of providing water under sub. (4). (4) (a) The owner of land where the private water supply is located may submit the following information to the town, village or city where the private water supply is located: 1. Documentation from an action under sub. (2) or (3) showing that the department or the department of justice is seeking to obtain treatment, repair or replacement of the damaged private water supply. 2. A declaration of the need for an immediate alternative source of water. (b) A person who submits information under par. (a) may file a claim with the town, village or city where the private water supply is located. The town, village or city shall supply necessary amounts of water to replace that water formerly obtained from the damaged private water supply. Responsibility to supply water commences at the time the claim is filed. Responsibility to supply water ends upon notification to the town, village or city that an order under sub. (2) or (3) has been complied with or upon a finding that the regulated activity is not the cause of the damage. (c) If the department or the court does not find that the regulated activity is the cause of the damage to a private water supply, reimbursement to the town, village or city for the costs of supplying water under par. (b), if any, is the responsibility of the person who filed the claim. The town, city or village may assess the owner of the property where the private water supply is located for the costs of supplying water under this subsection by a special assessment under s. 66.0703.
