Groundwater Quality · Website information
Editorial and Sources
Authorship, AI assistance, research methods, publication dates, corrections, and the boundaries of this restored edition.
Two clearly identified kinds of material
The archive preserves the original groundwater-quality.org portal, including historical Friends of Groundwater and World Water Quality Alliance references. The new Articles collection is an additional explanatory edition. It is not represented as new work commissioned, reviewed, or endorsed by those original organizations.
Authorship and assistance
“Groundwater Quality Editorial Desk” is an organizational byline for the new restoration-era guides. These guides were prepared with AI assistance and desk research. It is not the identity of a licensed water professional or a claim of independent expert peer review. No named scientist’s approval, interview, field campaign, or laboratory experiment is claimed.
Research method
We frame a narrow question for each guide, consult linked primary research or official public-health and environmental guidance, separate reported findings from interpretation, and identify the limitations that affect application. Numerical examples and project workflows are hypothetical unless explicitly attributed to a source. They are included to explain reasoning, not as invented field observations.
Source selection
Sources include original research papers and official resources from organizations such as USGS, WHO, CDC, EPA, and relevant public agencies. Authority alone does not make every source applicable to every place. Geographic coverage, sampling stage, analytical method, publication date, scenario, and local law are part of the interpretation. Historical assessments are identified by their date.
Water-safety boundaries
Articles do not certify supplies, diagnose exposure or disease, design treatment, or replace local professional assessment. Regional predictions do not establish an individual well’s chemistry. Household water-use decisions should be discussed with the responsible authority and qualified professionals. The new guides deliberately avoid chemical disinfection recipes and unsupported removal guarantees.
Dates and updates
The collection was prepared and reviewed on 14 November 2026. It is available for advance reading with staggered planned publication dates. Pages label those dates as planned until reached, rather than pretending that preparation happened earlier. Review dates are separate from publication dates. A future revision should identify substantive changes and update the review date after the work is actually done.
Images
Each new article has a different representative photograph. Source captions link to USGS, US government, or Unsplash resources. Images are optimized and served locally. Photographs do not establish a contaminant result and are not presented as fieldwork by this editorial desk. Historic figures retain their source context.
Corrections
A useful correction identifies the page, exact statement, proposed correction, primary supporting evidence, and date checked. The current response-channel status is shown on Contact. No active address has been verified from the restored source. Claims about new contact services should only be added after the operator verifies them.
Limits of review
This is a desk-based educational publication with no original dataset and no independent clinical, engineering, or regulatory review. Sources may be revised after the stated review date. Check the current original document before using a fact for a consequential decision.
