"Contaminant"means anything that impairs the quality of groundwater to a degree that creates a potential hazard to the environment, public health, or interferes with a beneficial use.
"County hydrogeologist"means a Washington State licensed hydrogeologist that either works for or has a contract with San Juan County.
"Critical water resource area"means selected watersheds and critical aquifers where resources potentially are threatened by seawater intrusion or primary contaminants, or limited due to poor recharge. These areas may be designated by resolution by the San Juan County board of health in response to recommendations by the department of health and community services based on studies conducted by the County or state, or by petition from community groups and community water systems.
"Cross-connection"means a physical arrangement connecting a potable water supply, directly or indirectly, with an unsafe water supply or other contaminating material, and capable of contaminating the potable water system.
"gpm"means gallons per minute.
"Group A public water system"means a public water system serving 15 or more connections or an average of 25 or more people per day for 60 or more days within a calendar year.
"Group B public water system"means a public water system with (A) more than two and less than 15 connections; or (B) serving an average nonresidential population of less than 25 people per day for 60 or more days within a calendar year; or (C) any number of people for less than 60 days within a calendar year. (Note: Systems with 10 or more connections typically will become Group A water systems based on population.)
"GWI"means groundwater under the influence of surface water. Any water beneath the surface of the ground where natural conditions cannot prevent the introduction of surface water pathogens into the source at the point of withdrawal.
"Health officer"means the duly appointed San Juan County health officer, or a representative authorized and under the direct supervision of the health officer.
"Inactivation"means an existing water system that ceases operation as a public water system.
"Inadequate"means a water supply that does not meet the definition of adequacy, as defined in this section.
"Individual water system"means a water system serving no more than two single-family residences, or four or fewer residences meeting the definition under "Same farm." (Note: A water system consisting of two main residences with ADUs is not defined as a Group B water system under this provision.)
"Owner"means owner of the proposed or existing well or water system.
"Peak demand"means the amount of water needed to supply maximum demand or meet extreme conditions, in compliance with Chapter
246-290 WAC.
"Potable"means water safe for human consumption.
"ppm"means parts per million. Equal to milligrams per liter (mgl).
"Project actions"means an application for a land division, a new and/or expanding water system, and/or a certificate of water availability. Project actions do not include simple land divisions or building permit applications for structures that do not require certificates of water availability.
"Purveyor"means an agency, subdivision of the state, municipal corporation, firm, company, mutual or cooperative association, institution, partnership, or person or other entity owning or operating a public water system, or applying to create a public water system. Purveyor also means the authorized agent of these entities.
