Editorial standards

We would rather say less and be right. Every guide and tool on Septic & Well Guide follows these rules.

Sources we use

We rely on the U.S. Environmental Protection Agency (SepticSmart, private wells, and drinking water standards), the U.S. Geological Survey, the CDC, and land-grant university extension services such as Penn State Extension. Where rules differ by state, we say so and point you to your state or local health department.

We cite the primary source whenever one exists: the statute, the agency page, the court rule, or the extension publication. News articles and industry groups are used only for context and are labeled as such. Each guide lists its sources at the bottom with links.

What we will not do

• We do not invent statistics, testimonials, reviews, expert quotes, or credentials.
• We do not present estimates as measurements. Where a number is a rule of thumb or a model, the page says so and explains the math.
• We do not accept payment to include, rank, or recommend anything in our guides.
• We never ask readers to click ads, and ads are always labeled “Advertisement.”

Tools and data

The pumping calculator uses the sludge-and-scum accumulation estimate published by Penn State Extension and shows EPA’s general guidance alongside it. The well test reader uses EPA’s National Primary Drinking Water Regulations and secondary standards. Each tool explains its assumptions on the page.

Review and updates

Each guide shows the date it was last reviewed. We re-check sources when we learn a rule has changed and at least once a year. When a change matters to readers, we note it on the page.

Corrections

If you find a mistake, use the contact form and include the page and a source. Confirmed errors are fixed promptly, and substantive corrections are noted on the page with the date.

Limits

Septic and well rules are set by states and local health departments and vary widely. This site is general information, not engineering, legal, or medical advice. Never enter a septic tank: the gases inside can kill. For a failing system, contaminated water, or health symptoms, contact a licensed professional or your local health department.
