Local pages for the water around you.

Why we build a page per town rather than one page per state

Two properties fifteen miles apart can need completely different equipment. They may be fed by different utilities, from different reservoirs or aquifers, treated with chlorine in one case and chloramine in the other, and built in eras with entirely different plumbing.

A single page covering a whole state cannot carry any of that. It ends up describing water in general, which helps nobody decide anything. So each area page names the utility, its source water, the treatment method, the reported hardness, and any contaminants of note, with the report each figure came from and the year it covers.

Where we do not hold a sourced figure for a town, the page says so rather than guessing. An unsourced number on a page like this is worse than a blank, because it looks like information.

How to read what is on an area page

Figures published by a utility describe the water in its distribution system, usually as an average or a range across many sampling points. Your own tap can differ, and for lead it almost certainly does, because lead is picked up from the service line and interior plumbing rather than carried from the treatment plant.

So treat the local page as the starting point for the right questions rather than as a measurement of your kitchen. Our guide to reading a water quality report explains which rows matter and how to find the report for your own address.

Coverage

We work across four states. Our area list currently holds 113 municipalities with a population of 50,000 or more, drawn from Vintage 2024 (POPESTIMATE2024) of the Census sub-county population estimates. Smaller towns are served too, and they are reached through the nearest listed area.

States not yet published

Contractor registration has to be in place, and displayed, before a company advertises home improvement services into these states. New Jersey, Pennsylvania, and Connecticut each require a registration number on advertising, and work in the five New York City boroughs additionally requires a city licence, as do several New York counties.

We do not publish local pages for a state until those details are on file, because the page itself would be the advertisement. The following states are prepared and waiting on that step.

• New Jersey. 39 areas prepared.
• Pennsylvania. 17 areas prepared.
• Connecticut. 19 areas prepared.
• New York. 38 areas prepared.

Current registration status is published on our licensing page. If you are in one of these states and want to talk in the meantime, the form on this page reaches us either way.

What we cover in every area

Residential and commercial water testing, filter and softener installation, well water treatment, repair of any brand, and scheduled filter replacement. The installation pages set out what each job involves and what has to be in place first.

Equipment choice follows the water rather than the postcode, so the filter comparison and the water problems pages apply everywhere we work.

Why some towns have a page and others do not

Two conditions have to be met before a local page appears, and both are deliberate.

The first is licensing. A local service page is an advertisement, and New Jersey, Pennsylvania, and Connecticut each require a home improvement contractor registration number to appear in advertising. New York licenses at city and county level instead, so work in the five boroughs needs a New York City licence and several counties run their own. We do not publish into a state before that registration is on file.

The second is research. A page is only built once we hold at least three separately sourced facts about that town's water, each with a publisher and a year. That threshold exists because a page carrying a place name and nothing else local is worthless to you and is exactly the pattern search engines penalise. If we have nothing true and specific to say about your town's water yet, we would rather have no page than a padded one.

The practical effect is that coverage fills in town by town as the research is done, rather than appearing all at once. Areas without a page are still served. They are simply not written up yet.

What a finished area page contains

The utility that supplies the town, with a link to its current annual report. The source water, whether that is a named reservoir, a river, or an aquifer. The disinfectant, because chlorine and chloramine need different filter media and getting that wrong is a common reason a filter disappoints. Reported hardness, which decides whether softening is worth discussing at all.

Then the local specifics: any contaminant of note with its reported level and the year, the position on lead service lines including whether the municipality publishes an inventory, and any local programme such as a free test kit or a funded replacement scheme. Every figure carries the publisher and the year it refers to.

If your town is not listed

The list covers municipalities of 50,000 people or more, which is a threshold for building pages rather than a boundary for doing work. Smaller towns sit inside the same counties, are often served by the same utilities, and are reached through the nearest listed area.

If you cannot find your town, use the closest one on the list or send us your address through the form. We will tell you whether we cover it before anything else is discussed, because there is no point working through your water if we cannot reach you.

Sources we use for local water data

Utility Consumer Confidence Reports, the EPA Safe Drinking Water Information System, EPA UCMR 5 monitoring data, the state environmental and health departments for New Jersey, Pennsylvania, Connecticut, and New York, the New York City Department of Environmental Protection annual report, and municipal lead service line inventories.

Population and geography come from the Census Bureau sub-county population estimates and the Census Gazetteer. Every figure on an area page carries its publisher and year, and utility reports are normally published by July 1 each year for the preceding calendar year.
