Local water dashboard
Official source aggregationRegional hardness evidence, possible serving systems, EPA compliance history, and the measurements that are—and are not—available for Clark County.
Your tap water
Match the utility name to your water bill. These results describe the utility’s water, not a test at your home. A ZIP can include several water systems.
280 ppm average
Utility-reported hardness as CaCO₃ · 2026 published summary
Reported average: 280 ppm (16.4 GPG).
The utility summary reports an average of 280 ppm. A range is not provided. This applies to Las Vegas Valley Water District, not every provider with a Las Vegas mailing address.

How to use regional evidence
These samples describe nearby environmental water. They cannot establish whether your tap water is soft or hard. Use a utility result or a tap test for appliance settings and treatment sizing.

Evidence-first next steps
This profile can help you ask the right question. It cannot select equipment for a property without a current result from the serving utility or the tap.
ZIP boundaries and utility service areas do not perfectly match. Verify the system on a water bill before relying on system-wide records.
Use the current Consumer Confidence Report for treated-water results and official notices.
Read Las Vegas Valley Water District’s report ↗Use a tap hardness test before sizing a softener. For health concerns, use a certified laboratory and the correct sampling protocol.

Estimates can differ across a city because monitoring locations and associated systems differ.
Frequently asked
EPA ECHO shows no active health-based violation for the associated systems in this reporting snapshot. This does not prove every contaminant is absent; federal records can lag and household plumbing can change tap conditions.
See the utility-reported ranges above and confirm which provider serves you. Values can vary within a system and over time.
Confirm hardness at your tap and consider actual scale or spotting before choosing treatment. Regional environmental values cannot determine whether you need a softener. A softener addresses hardness, not every contaminant.
