BEST OF STATE
Every statistic on Blue Best's city and county pages comes from verifiable public records, utility reports, federal datasets, or our own operational records, and every page footnote links here, to the exact source.
Found an error? Email info@bluebest.com and we verify and correct within 5 business days.
Every figure on our local pages is one of: (a) public government data (Census, USGS, NOAA, EPA, state agencies); (b) utility data (municipal water reports, Rocky Mountain Power, Enbridge Gas); (c) industry standards (DOE, EPA, ASHRAE, ACCA, WQA); or (d) Blue Best's own records, labeled as such. Each city's data is researched independently for that city. (They genuinely differ: Tooele's water runs about a third as hard as Ogden's.)
Review cadence: water reports annually (CCRs publish each spring), EPA status, incentives quarterly, federal tax policy every January, Census annually.
Primary sources, each city's official water report (CCR).

Salt Lake City
One of the few Utah CCRs that publishes hardness: calculated 7.1 / 9.2 / 10.2 / 11.6 grains per gallon by treatment plant (individual sources to about 28.6). Verified June 2026. Salt Lake City Public Utilities 2025 Water Quality Report

West Valley City
Granger-Hunter Improvement District (serves most of the city). About 13 GPG district and third-party estimate; official CCR verification pending.
West Jordan
Jordan Valley Water Conservancy District supply data. About 8 GPG district estimate; city CCR verification pending.
Park City
Park City Municipal water quality reports.
Classification and impact: USGS Water Hardness Classification (soft, moderate, hard and very hard thresholds; US averages) and the Water Quality Association (scale impact on water-heater lifespan and efficiency).
City
Hardness (GPG) and source
Provo
10–15 typical. Source: Provo City 2024 Water Report.
Sandy
8–25 (zone and seasonal). Source: Sandy City system reports (third-party).
Layton and WBWCD-supplied Davis cities
10–18 (171–308 ppm). Source: Weber Basin WCD 2024 CCR (wholesale supply; city wells add variance).
Orem
5.7–9.9 ground, 7–25 surface. Source: Orem 2024 CCR hardness table (60% surface / 40% ground).
Bountiful
18–38 (well and season dependent). Source: 2024 CCR sources, 60% city wells plus Mill Creek, and field observations.
Riverton
10–15 (JVWCD) or 33–35+ (city wells). Corroborated; CCR on issuu. Source: JVWCD supply data plus corroborated well measurements.
Ogden
10–24 (seasonal and source dependent). Source: 3 source types, Ogden system plus WBWCD plus Pineview.
Tooele
8.5–18 (well dependent). Source: 12 wells and 2 springs (Tooele 2024 CCR); city-area data about 8.5, third-party up to about 18.
Grantsville
Well dependent (estimated about 10–20). Source: Grantsville City wells; third-party estimates only.
Park City
About 26 third-party (hard). Source: Park City Municipal, 8 sources (wells, spring, Spiro and Judge mine tunnels, Rockport, JSSD import) and 3 plants.
Update frequency: annually (most Utah CCRs publish May to July). Methodology note: hardness is not a federally required CCR analyte, so many Utah cities don't publish it. Our June 2026 reads of the Sandy, Bountiful, Ogden and Tooele CCRs confirmed all four are silent on hardness. Where the official report is silent, we label values as estimates and measure actual hardness at your home before recommending equipment.

NOAA station (ID)
Serves, annual heating and cooling degree days
PROVO BYU (USC00427064)
Provo and the Utah County valley. Annual heating degree days 4,968. Annual cooling degree days 1,205.
SALT LAKE CITY INTL AP (USW00024127)
Salt Lake City, and Sandy approximately (the bench runs cooler). Annual heating degree days 5,154. Annual cooling degree days 1,420.
OGDEN PIONEER P H (USC00426404)
Ogden and Weber County. Annual heating degree days 5,508. Annual cooling degree days 1,136.
TOOELE (USC00428771)
Tooele and Tooele County. Annual heating degree days 5,791. Annual cooling degree days 1,087.
KAMAS (USC00424467)
Park City area (Park City sits about 500 ft higher, so it runs colder). Annual heating degree days about 7,589. Annual cooling degree days about 193.
All values verified against NCEI normals June 2026. Layton has no in-city normals station; nearby stations bracket it at roughly 5,600 to 5,750 heating degree days.
