In addition to the definitions in Chapter I, the following terms are defined for the purposes of this Chapter:

(a) Deficiencies means inadequacies that may be of health significance.

(b) Nonpublic water system means any water system that serves one or more dwelling units, not having an environmental health permit to operate issued by the Director or the State Department of Public Health. The system includes any collection, treatment, storage, or distribution facilities under control of the owner(s) of the system.

(c) Sell means conveyance of title to real property in exchange for the approximate fair market value of the property. Sell does not include a gift. Sell does not include a transfer between spouses. Sell does not include a transfer resulting in the addition or deletion of one or more co-owners to the title.

(d) Sanitary survey means the qualitative inspection of a water system and its physical environment to determine the quality of the water source and, to the extent possible, to uncover any condition that could potentially affect the safety or potability of that water. A sanitary survey would include an inspection of the well and storage and pressure tanks. It would also incorporate an investigation of the site location and adjacent properties in order to locate possible sources of chemical, pesticide, or sewage contamination that could pollute the water supply. A survey would also normally include a review of the results of water tests specified by the Director.

(e) Water system inspection report means the documented findings of sanitary surveys and of water quality tests to be included in the survey. The report includes a description of any identified water system deficiencies.
