Checking Public Drinking Water Records for a Mobile Home Community: Scope and Limits

Published September 9, 2026

Research question

What can federal public drinking water records show when researching a mobile home community's water system?

This review is limited to regulated public water systems in the published data. Its unit of analysis is a system record, monitoring entry, or enforcement field. The distinction matters because a public program record may describe a system, geography, rule, survey population, or administrative process rather than a particular home.

Finding

The sources can support a carefully dated statement about what the publisher records and how it defines the measure. They do not, by themselves, establish a home's condition, legal status, value, eligibility, compliance, or future outcome.

That boundary is the main result of this review. A public page is useful when the research question matches its universe and unit. A local decision needs the controlling property record and, when appropriate, review by a qualified professional or public authority.

Method

We opened the four official pages listed below on September 9, 2026. For each page, we recorded the agency, page title, direct URL, publication or revision date when shown, geographic coverage, record unit, definitions, and warnings. We then compared those fields with the research question before drafting the finding.

We did not estimate a new total, inspect a home, identify a resident, interpret a contract, or decide whether a property meets a requirement. No private property files or MobileHomeBiz analytics were used.

Reproduction steps

Start with the primary program page and write down the program name exactly. Follow the publisher's links to definitions or technical material. Save the access date and any displayed release, effective, or map date. If the source provides a table filter, map layer, downloadable file, or record identifier, preserve the selection in words rather than relying only on a screenshot.

Next, create one source-log row for each statement you plan to publish. Copy the unit and universe from the documentation. Keep missing, suppressed, preliminary, and not-applicable values in their original state. Do not convert them to zero. A second reviewer should be able to reach the same source and explain why it fits the question.

If two pages use different periods, geographies, or definitions, report them separately. Do not calculate a difference or trend until those fields match. Record any judgment or inference in a separate note so it cannot be mistaken for agency language.

Scope and inference limits

This brief covers only the cited public pages as they appeared on the access date. Agency pages, downloadable files, maps, and regulations can change. An access date does not replace the source's own effective or reference date.

Administrative records reflect program rules and participation. Survey estimates may include sampling, weighting, imputation, revision, and disclosure limits. Map products depend on scale, layer, effective panel, and location accuracy. Regulations define requirements within their stated applicability but do not document field conditions at a particular home.

The public evidence cannot verify title, ownership, installation quality, utilities, structural condition, environmental exposure, insurance coverage, loan eligibility, resident circumstances, or compliance at a named property. It cannot prove causation or predict an individual result.

A responsible local follow-up

For a property-specific question, match the public source with the relevant permit, title, installation label, survey, inspection, utility record, map determination, service report, contract, or agency response. Record where the public evidence ends and the local evidence begins.

If the records conflict, check identifiers, dates, geography, definitions, and version history before assuming one is wrong. Route legal, engineering, environmental, appraisal, lending, insurance, tax, and safety conclusions to qualified reviewers.
