Water here is one authority but not one water. Truckee Meadows Water Authority is community-owned and supplies 475,000+ residents of Reno, Sparks and Washoe County from the Truckee River system (https://tmwa.com/), and it publishes quality by neighbourhood rather than by city: Central and Southeast Reno measured 62 mg/L (3.6 gpg) hardness in Q1 2026 while Southwest Reno measured 238 mg/L (13 gpg) - so we ask for the street, not the metro. Underneath, four USDA-NRCS series carry the slab story: the Reno series on alluvial fans with a duripan at 50-100 cm and low saturated hydraulic conductivity; the Washoe series on terraces with 35-50% rock fragments; the Truckee series on poorly drained flood-plain ground with a seasonal water table at 50-100 cm; and the Flex series, very shallow to weathered volcanic bedrock, on the hills of northwest Reno. We are an independent matching service, never a contractor - we do not install, inspect or guarantee any floor.
