A. 
A well site inspection report must be filed with San Juan County health and community services (H&CS) prior to drilling all new wells. This report may be completed by the well driller, a certified designer, licensed engineer, or H&CS. This report will include a plot plan on a consistent and standard scale indicating: parcel number, well i.d. number, well location coordinates, property lines and easements, existing and proposed buildings, marine shorelines, bodies of fresh water (including seasonal streams), existing and proposed roads and driveways, existing and proposed septic systems, any potential or existing source of contamination, and adjacent public and private water sources.
B. 
Well siting on lots utilizing an on-site sewage disposal system (OSS) shall contain a plot plan signed by the licensed well driller and an engineer or certified septic designer showing the proposed location of the OSS and well.
C. 
Well siting must meet the following criteria, or comply with the variance procedures in subsection (D) of this section:
1. 
Wells shall be located at least 100 feet from a drainfield and 1,000 feet from a solid waste landfill. Wells shall be located at least 100 feet from a septic tank and components, unless additional surface seal (double seal) or other H&CS approved mitigation is used.
2. 
Wells shall be located at least 100 feet from the neighboring property line, except:
a. 
Nothing herein shall prevent a well from being located within 100 feet of the neighboring property line provided the neighboring property owner has signed and recorded a sanitary covenant restricting the placement of any potential sources of contamination within 100 feet of said well; or
b. 
H&CS may grant a variance to allow a well to be located no less than 50 feet from the property line. Said variance must be granted prior to drilling the well. The variance must be supported by a vulnerability assessment. Variance requests and vulnerability assessments must be submitted by a qualified water system designer, well driller, or engineer and contain proposed mitigation measures.
3. 
Wells completed with six feet or more of impermeable material between the surface and water table must have a 100-foot sanitary setback, unless a variance is supported by a vulnerability assessment. A variance may be granted for no less than a 50-foot radius.
4. 
Wells completed with less than six feet of impermeable material must have a 100-foot sanitary setback. A variance to setback requirements may be issued by the Department of Ecology.
5. 
Shallow wells and springs must have a 100-foot sanitary setback and submit an inventory of all potential sources of contamination within 600 feet.
6. 
If the sanitary setback affects an adjacent property, the owner must obtain a sanitary easement, recorded with the auditor's office, prior to well construction.
D. 
If the siting requirements cannot be met the applicant must submit a vulnerability assessment by a qualified water system designer, well driller, or engineer, with proposed mitigation measures.
E. 
Failure to meet siting requirements will result in denial of any County permits requiring demonstration of potable water.

A. 
A well site investigation report must be filed with the department prior to drilling a new community water system well. The report may be completed by the well driller, a certified designer, licensed engineer, or the department. This report will include a plot plan on a consistent and standard scale indicating: parcel number, well i.d. number, well location coordinates, property lines and easements, existing and proposed buildings, marine shorelines, bodies of fresh water (including seasonal streams), existing and proposed roads and driveways, existing and proposed septic systems, any potential or existing source of contamination, and adjacent public and private water sources.
B. 
Well siting must meet the criteria as outlined in Chapter 246-290 WAC (Group A systems) or Chapter 246-291 WAC (Group B systems).
(Ord. 10-2001 § 5)
Well construction or modification must comply with standards in Chapter 173-160 WAC, Minimum Standards for Construction and Maintenance of Wells, and meet the standards below:
A. 
All wells shall have a permanent identifying tag attached with a unique number that conforms with Department of Ecology requirements. This number shall be recorded on the water well report.
B. 
All wells shall be equipped with a functioning water meter.
C. 
Shallow wells and springs must be constructed according to the standards in EPA Manual of Individual and Non-Public Water Supply Systems and Chapter 173-160 WAC, Minimum Standards for Construction and Maintenance of Wells.
D. 
In areas where seawater intrusion is indicated no well drilling activity shall go deeper than the fresh groundwater layer. Where these activities encounter potential seawater intrusion, the driller must construct the well to minimize the impact or decommission the well.
(Formerly 13.06.120; Ord. 14-1996; Ord. 14-2000 § 4; Ord. 10-2001 § 6; Ord. 20-2007 § 4; Ord. 22-2013 § 5)
No new well shall be constructed within the service area of an existing public water system without written notice to the system purveyor. Well construction must comply with covenants and restrictions, and/or provisions of the approved water system's plan or design.
New development inside a Group A service area or an urban growth area may not develop a new well to serve existing or proposed lots if the designated service provider has the willingness and capacity to serve. This provision is subject to the water system's capacity to provide timely and reasonable service based on their water system plan, or within 120 days, but does not limit the right of the purveyor to require conditions and payment of fees and costs associated with new service connection.
