Well Log Requirements
The well log must include (per OAR 690-205-0210):
- Owner name, exact location (GPS, TRS, address)
- Dates of drilling and completion
- Depth and lithology (detailed formation descriptions)
- Water-bearing zones encountered
- Casing sizes, materials, and depths
- Grouting/sealing information (method, depth, materials)
- Pump test data (if conducted)
- Static water level and yield
Construction Standards (OAR 690-210)
Casing Materials
| Material | Requirement | Notes |
|---|---|---|
| Steel | New ASTM-A53, minimum Schedule 10 | Welded joints required |
| PVC | NSF-certified SCH 80 PVC 1120/1220 | Must be installed in oversize hole (no driving); solvent-welded joints |
| Fiberglass | NSF-61/ASTM D-2996 compliant | Proper joint sealing required |
Annular Seal (Grouting)
- All annular spaces must be fully grouted from bottom to land surface
- Approved methods: pressure cement grout or bentonite
- Unconsolidated sands: Full-depth borehole at least 4″ oversize to 18 ft depth, pack gravel, then grout annulus to surface
- Clay-bearing soils: Casing must extend ≥5 ft into clay (or 18 ft if clay is shallower); annulus grouted to that level
- Consolidated rock: Casing must be set ≥5 ft into sound bedrock
- Surface completion: Minimum 4-inch thick slab, 2 ft from casing, sloped to drain
Setback Requirements
| Contamination Source | Minimum Distance |
|---|---|
| Septic tanks or closed drains | 50 ft |
| Septic drainfields or sludge disposal | 100 ft |
| Residential fuel tanks | 25 ft |
| Commercial fuel tanks | 50 ft |
| Roof runoff or manure holding | 50 ft |
| Hazardous waste sites | 500 ft (with Dept. permission) |
Disinfection
- All pumping equipment, sand, gravel, and casing must be rinsed and pre-disinfected with ≥50 ppm chlorine before placement
- Upon completion, flood well with chlorine so that 25 ppm residual remains after 24 hours
- Tools and well interiors must be oil/grease-free
- After pump installation, re-discharge with chlorine before placing in service
Permits
Water Rights
Oregon differentiates exempt and permit groundwater uses (ORS 537.545):
- Exempt: Single domestic use up to 15,000 gallons/day (roughly 10 acre-ft/year); serves up to 3 homes
- Permit required: High-capacity, municipal, industrial, or irrigation wells exceeding exempt limits
- Permit applications filed with OWRD regional office (often requiring hydrogeologic report and pump test)
Special-Purpose Drilling
- Monitoring Wells: Licensed Monitoring Well Constructor required; start card ($350) and well log
- Geothermal Wells: Regulated by DOGAMI Mineral Land Reclamation permits + OWRD water-right permits
- Geotechnical Holes: Deep test holes require start card and fee; shallow soil probes exempt
Drilling Conditions by Region
Geology: Fractured volcanic and sedimentary rock (shale, basalt, sandstone)
- Typical depths: 50–300 ft
- Shallow wells encounter logjammed soils and gravels
- Casing needed to prevent caving
- Higher contamination risk (surface water intrusion)
Geology: Deep soils over basalt; gravel/sand aquifers or basalt flows
- Typical depths: 100–300 ft
- Glacial clays and dense sand/gravel (abrasive)
- Deep hood screens often needed
- Bacteria and nitrate concerns in developed areas
Geology: Columbia River Basalt flows; basin-fill sediments
- Typical depths: 300–600+ ft (some exceed 1,000 ft)
- Hard basalt requires heavy-duty HSA drilling
- Lost-circulation zones and blowouts possible
- Many artesian (pressurized) wells
- High dissolved minerals (iron, manganese, arsenic)
Geology: Fractured volcanic and metamorphic rock
- Typical depths: 200–400+ ft
- Fractured rock wells with variable yield
- Seasonal recharge variations
- High rainfall, shallow water tables
Special Zones & Requirements
Arsenic Advisory Areas
Certain regions have naturally high arsenic in groundwater. Notable hotspots:
- Sweet Home/Linn County: ~25% of wells above 10 ppb EPA limit
- Tualatin Basin (NW Portland metro): Elevated arsenic in some wells
- Cottage Grove/Creswell (Lane County): Known arsenic occurrences
- Eastern Oregon (Ontario area): Arid basins with arsenic
Ensure tight seals and proper disinfection. Recommend arsenic testing to homeowners in these areas.
Nitrate-Contaminated Areas
- Lower Umatilla Basin (Morrow/Umatilla counties): Designated Groundwater Management Area since 1990
- Irrigated farmland and livestock areas (Klamath Basin, Mid/Blue Mountains)
- Recommend annual nitrate testing for wells in agricultural regions
Wellhead Protection Areas
Wellhead Protection Areas around public supply wells have restricted land use. Consult Oregon Health Authority's Source Water Protection maps and county plans when siting wells near municipalities or known pollutant sources.
