The WaterTreatmentChemicals.net editorial team takes 4 kinds of messages: corrections, suggestions, quote requests and press or partnership questions. Which channel fits which message, and what makes a correction quick to check?
The site is an independent reference that sells no chemical and organizes its pages in 16 chemical families. Every page answers one question set about water treatment chemicals dosed in industrial, municipal and utility systems.
Every value on this site is checked against primary sources (NSF listings, AWWA, CEN, EPA, eCFR, the Federal Register, EUR-Lex, ECHA, WHO and PubChem); see our methodology and fact-checking process.
How Do I Contact the WaterTreatmentChemicals.net Editorial Team?#
Contact the WaterTreatmentChemicals.net editorial team through the form on this page, which asks for an email address, a topic and the message. Email sent to editorial@watertreatmentchemicals.net reaches the same team.
The 4 message types and where each one goes are listed below.
| Message type | Channel | What to include | What happens |
|---|---|---|---|
| Correction | contact form, correction topic | page URL and section; value as printed; primary source with section or edition and date; jurisdiction | checked against the issuing primary source; an accepted correction is made on the page with a dated note |
| Suggestion (source, chemical, rule change, topic) | contact form, suggestion topic | the source link or instrument; the chemical's water-treatment use; the system | reviewed against the site's scope; publication is not promised |
| Quote request (program or chemical) | the program quote or chemical quote button below | system, size, location, problem; or chemical, grade, NSF/ANSI/CAN 60 need, volume, packaging, country | passed to independent providers and suppliers |
| Press or partnership | contact form, press or partnership topic | outlet or company, subject | answered under the editorial policy; no paid placement in editorial content |
Footnote: No reply time is promised for any message type.
Form submissions are kept for 24 months, as the privacy policy sets out.
How Do I Report an Error or Request a Correction?#
Report an error through the contact form with the correction topic: name the page, quote the value as printed and give the primary source that shows the correct value. What makes a correction report quick to check?
What should a correction report include?#
A correction report should include 5 items, and a report with all 5 is the quickest to check. The 5 items are listed below.
- Name the page URL and the section heading.
- Quote the value, date or citation as printed on the page.
- Give the primary source: issuer, instrument or standard with its section or edition, and the date you read it.
- State the jurisdiction (US federal, a US State, Canada, EU, WHO or another country), because limits differ by jurisdiction.
- Send it from an email address that can receive a question about the source.
Citations in the site's own form are easiest to check, such as "40 CFR 141.80(c) as amended by LCRI, 2024-10-30" for the US lead action level of 0.010 mg/L (10 µg/L), "ANSI/AWWA B403-24" or "NSF listings, 2026-10-21".
Which primary sources is a correction verified against?#
A correction is checked against the primary source that issued the value, never against a secondary website. Vendor brochures and encyclopedias can point to an error; only the issuing body settles it.
The 10 primary sources and what each one settles are compared in the table below.
| Primary source | Issuer | What it settles | Example as cited on the site | Where the site covers it |
|---|---|---|---|---|
| NSF/ANSI/CAN 60 listings | NSF International | product-specific maximum use levels (MUL), as product, total across all application points | "NSF listings, 2026-10-21" | NSF/ANSI/CAN 60 |
| AWWA B-series standards | American Water Works Association | product specifications and current editions; 49 standards from B100-25 to B703-24 | "ANSI/AWWA B403-24" (aluminum sulfate) | AWWA B-series standards |
| EN standards (CEN/TC 164, WG 9) | European Committee for Standardization | European purity specifications for drinking-water treatment chemicals, by full edition | "EN 878:2016" (aluminum sulfate) | EN standards for drinking water treatment chemicals |
| EPA guidance and profiles | US Environmental Protection Agency | supply-chain and program facts; 47 water treatment chemical supply chain profiles, 36 of them used in water treatment | "EPA Water Treatment Chemical Supply Chain Profiles, updated 2026-06-30" | the pages each profile concerns |
| eCFR | US Office of the Federal Register (codified text) | current US federal limits with section | "40 CFR 141.80(c) as amended by LCRI, 2024-10-30" | water treatment regulations and standards |
| Federal Register | US Office of the Federal Register | proposed versus final rules and their dates | "perchlorate: proposed rule only, 2026-01-06" | the pages each rule concerns |
| EUR-Lex | Publications Office of the EU | EU acts by number and article | "Directive (EU) 2020/2184, Article 12 (treatment chemicals)" | EU Drinking Water Directive 2020/2184 |
| ECHA (CLP and C&L Inventory) | European Chemicals Agency | GHS classification, labelled "harmonised (CLP Annex VI)" or "notified (ECHA C&L)" | "sodium hypochlorite, harmonised (CLP Annex VI): H314, H318, H400, H410" | each chemical's own page |
| WHO Guidelines for Drinking-water Quality | World Health Organization | international guideline values by current edition | "fourth edition incorporating the first, second and third addenda, 17 June 2026" | WHO Guidelines for Drinking-water Quality |
| PubChem | US National Library of Medicine (NCBI) | chemical identity: CAS number, formula, molar mass | "aluminum sulfate CAS 10043-01-3 (10043-67-1 is potassium alum)" | each chemical's own page |
How each value is sourced and checked before publication is set out in our methodology and fact-checking process.
What happens after a correction is accepted?#
An accepted correction is made on the page itself: the value is replaced with the one the primary source states, the source and date are cited, and a dated correction note records what changed. A newer official source beats the published value, and every page stating the old value is corrected.
Corrections are never traded for placement. The full rules are in our editorial policy on corrections.
Can I Suggest a Source, a Chemical or a Topic?#
Suggestions are welcome inside the site's scope: chemicals and media that a water-treatment operator, engineer or utility doses or specifies in an industrial, municipal or utility system. A suggested chemical may already have a page. Check the water treatment chemical database first.
The 4 suggestion types the editorial team reviews are listed below.
- Primary sources: a newer NSF listing, AWWA or EN edition, eCFR text or EUR-Lex act.
- Chemicals and media with a real water-treatment role.
- Rule changes: a Federal Register proposal, final rule or compliance date.
- Topics in a covered system, such as boiler, cooling-tower, membrane or wastewater treatment.
Pool, spa, pond, aquarium and household water topics are out of scope. Publication of a suggestion is not promised.
Rule and listing changes reported this way feed water treatment chemicals news and the pages they affect.
How Do I Request a Program Quote or a Chemical Quote?#
Request a program quote or a chemical quote with the two quote buttons below, because providers and suppliers need system and chemical details. WaterTreatmentChemicals.net sells no chemical and runs no treatment program: quote requests go to independent providers and suppliers.
A program quote covers a whole treatment program, such as a boiler, cooling-tower or wastewater program. A chemical quote covers supply of one chemical by grade, volume and delivery country. How supplier types differ is explained under water treatment chemical suppliers and manufacturers.
Press, Advertising and Partnership Inquiries#
Press, advertising and partnership inquiries use the contact form with the press or partnership topic, and none of them buys a place in editorial content. Rankings and comparisons on the site are never paid, and any paid listing is marked sponsored. Market figures always name their publisher and year.
The rules on independence apply to every inquiry and are set out in the editorial policy on independence and lead partners.
What Can the Editorial Team Not Answer by Message?#
The editorial team does not answer 4 kinds of messages: chemical emergencies and exposures, out-of-scope uses, purchase or program requests, and requests for a named expert opinion.
Is this contact form for chemical emergencies or exposures?#
No: for a chemical release or exposure, call emergency services or poison control and follow section 4 of the product's safety data sheet (SDS). The form reaches the editorial team, not a response service.
Are pool, spa, household and other non-plant questions answered?#
No: pool, spa, hot-tub, pond and aquarium chemistry, household and emergency water treatment, and medical, food, cosmetic and agricultural uses are outside the site's scope. The same chemical in an industrial, municipal or utility system is in scope.
Does WaterTreatmentChemicals.net sell chemicals or run treatment programs?#
No: the site sells no chemical and runs no program, and quote requests go to independent providers and suppliers. It gives no site-specific engineering or compliance sign-off. Comparing providers is explained under how to choose a program provider.
Who writes the pages on WaterTreatmentChemicals.net?#
Every page is published under the byline WaterTreatmentChemicals.net Editorial Team, and every value is checked against its primary source before publication. No page is signed by a named individual. Who runs the site is described on about WaterTreatmentChemicals.net.
