Water Quality Testing in Las Vegas, Nevada

It is hard, and that is the headline. SNWA reports valley water at about 280 parts per million, roughly 16 grains per gallon, among the hardest municipal supply in the country, drawn largely from Lake Mead and the Colorado River. It is disinfected with ozone and then chlorine, not chloramine, which matters when you are choosing filtration because the two need different media. Beyond hardness, the things worth testing for at the tap are lead and copper picked up from interior plumbing rather than from the supply.

Not usually for safety, since the supply is treated and monitored. Testing at the tap is worth doing for two other reasons: to size treatment equipment properly rather than guessing, and to check for lead or copper leaching from your own pipework, which the utility's testing at the plant cannot tell you. Older homes with original plumbing are where that second reason matters.

Then annual testing is genuinely important, because nobody else is doing it. Well owners should test at least once a year using a STATE-CERTIFIED LABORATORY, and more often if the property sits near a known source of concern. Bacteria, nitrates and, in some areas, PFAS are worth screening for. A result only carries weight if the sample was collected properly and analysed by a certified lab.

Properly, or the result is meaningless. Samples are collected from the tap following a defined procedure, sealed, labelled and sent to a certified laboratory that measures with equipment far more precise than a home kit. A hardware-store test strip tells you roughly whether water is hard; it does not produce a number you can act on or a result anyone else will accept.

Match treatment to the actual water rather than to a sales pitch. Hardness points to a softener or conditioner; taste and chlorine point to carbon filtration; lead or copper from interior plumbing points to point-of-use filtration or, eventually, to repiping. We interpret the report in plain language and tell you where treatment genuinely helps and where it would be money spent on a problem you do not have.

For scale, often yes, because hard water shortens the life of water heaters, fixtures and appliances across the whole house rather than at one tap. For drinking water specifically, a point-of-use reverse osmosis system does a better job than whole-house filtration at a fraction of the cost. Many households end up with both for different reasons, and we will tell you which one actually addresses what your test showed.

Nevada requires a state contractor's licence issued by the Nevada State Contractors Board, and you can verify any licence free at nvcontractorsboard.com before you hire. Active Plumbing holds licence #0047021 and has worked the valley since 1991, with a 4.9 star rating across more than 860 Google reviews. Ask for the number rather than a reassurance, and ask for proof of liability insurance at the same time.
