The owner or manager of a water supply system that is operated by a volunteer shall maintain a record of each volunteer operator showing the name of the volunteer, contact information for the volunteer, and the time period for which the volunteer is responsible for operating the water supply system.
(b) An owner, agent, manager, operator, or other person in charge of a water supply system that furnishes water for public or private use may not knowingly furnish contaminated drinking water to a person or allow the appliances of the water supply system to become unsanitary.

(f) A public drinking water supply may not be connected to a sprinkling, condensing, cooling, plumbing, or other system unless the connection is designed to ensure against a backflow or siphonage of sewage or contaminated water into the drinking water supply.
(g) On discovery of a connection in violation of Subsection (e) or (f), the local health authority shall give written notice to the owner or agent maintaining the condition. The owner or agent shall make the necessary corrections to eliminate the condition.

(2) an act of terrorism against the public water supply or wastewater system;
(3) an unauthorized attempt to probe for or gain access to proprietary information that supports the key activities of the public water supply or wastewater system;
(4) a theft of property that supports the key activities of the public water supply or wastewater system; or
(5) a natural disaster, accident, or act that results in damage to the public water supply or wastewater system.
