Frequently Asked Questions About Water in Northwest Arkansas

Test your water. That is genuinely the whole answer. Symptoms point at possibilities — orange staining suggests iron, scale suggests hardness — but the things that matter most for health are invisible, and the things that look alarming are sometimes harmless. Testing settles it.

The in-home water test is free. Where your situation calls for certified laboratory analysis — bacteria, nitrate, lead, arsenic or PFAS, none of which can be measured reliably in a kitchen — we will explain what that involves and what it costs before anything is sent to a lab. Nothing gets charged without you agreeing to it first.

Benton, Washington, Madison and Carroll counties, including Fayetteville, Springdale, Rogers, Bentonville, Bella Vista, Siloam Springs and the rural areas between. See service areas.

We will tell you what your results support, which is sometimes a system and sometimes nothing. No same-day pricing, nothing to sign during the visit, and no electrolysis demonstrations.

It depends entirely on your source. Ozark groundwater dissolves minerals from limestone and private wells here frequently test hard. Treated surface water originating in Beaver Lake, which supplies much of the Fayetteville-Springdale-Rogers-Bentonville corridor, generally behaves differently. We will not quote you a regional average, because the number that matters is yours.

Public water systems in Arkansas are regulated and monitored, and are required to meet federal and state standards. Your utility publishes an annual Consumer Confidence Report showing what was found. Filtering treated municipal water is usually a choice about taste and preference rather than safety.

A private well is not monitored by anyone. No agency tests it and no annual report arrives. Annual testing for total coliform bacteria and nitrate is the widely recommended baseline.

Karst is landscape formed in soluble rock — limestone, in the Ozarks — where water carves fractures, conduits and caves. It matters because water can travel through karst quickly, with less natural filtration than a sandy aquifer provides, so surface contamination can reach groundwater faster. It is a good reason to test a well rather than assume it.

Search for your utility’s name plus ‘Consumer Confidence Report’ or ‘annual water quality report’. Every community water system publishes one each year. We are glad to look yours up.

A softener removes hardness minerals by ion exchange — it addresses scale, lathering and spotting. A filter removes or adsorbs other things — sediment, chlorine, iron, taste and odour. They do different jobs and many properties need both.

They control scale, in suitable water. They do not remove hardness, so your hardness test reads the same, soap does not lather better, and water does not feel soft. They are a legitimate technology sold under a misleading name. See salt-free water conditioning.

Where the problem shows up decides it. Kitchen-tap complaints are far cheaper to solve at the kitchen tap. Shower, laundry and appliance problems need point-of-entry treatment.

It varies enormously by equipment type, water quality and maintenance, and we will not quote a lifespan for a product we have not specified against your results. Each service page sets out typical replacement intervals for consumables.

We can fit a filter certified under NSF/ANSI 53 or 58 for lead reduction at the tap you drink from. Note that lead usually enters from your own plumbing rather than the supply, which is why point-of-use treatment is the standard approach. See lead in drinking water.

Certain reverse osmosis systems and carbon blocks are certified for PFOA and PFOS reduction. We will show you the certification for a specific model rather than making a general claim. See PFAS in drinking water.

For bacteria, yes — a rolling boil for one minute is the standard recommendation. For nitrate, lead, arsenic and PFAS, boiling makes it worse, because water evaporates and the contaminant concentrates. Knowing which problem you have matters.

No. A softener is designed for hardness. It does not address bacteria, nitrate, arsenic, lead, PFAS or chlorine.

We cannot tell you that, and you should be cautious of any water company that does. Hard water leaves soap residue on skin, which is established chemistry, and many people report a difference after softening. Anything about a medical condition belongs with your doctor.

Every service page explains the factors that genuinely move the price, and we will give you a figure once we have seen your test results and your utility space.

NWA Water Pros specifies and supplies your system. Installation is performed by an independent licensed plumbing contractor.

Yes, routinely, including brands we do not sell. See water system maintenance.

It depends on the component and your water. Sediment cartridges can run one to twelve months, point-of-use carbon six to twelve, whole-house media three to five years, UV lamps annually without exception. Each service page carries a schedule.
