Methodology & Data Quality

How CleanBlock documents cleanup activity, protects privacy, and turns community action into useful environmental information.

Version 1.0Updated August 17, 2026

CleanBlock is designed to document litter that people actually remove from their communities.

A cleanup is more useful when we know not only that litter was removed, but also what was removed, approximately how much, and where the cleanup occurred.

This information can help communities understand litter patterns over time, document volunteer impact, identify common types of waste, support cleanup planning, and create a clearer record of environmental stewardship.

CleanBlock is not designed to track people's movements. Location information is used to document where litter was removed.

Depending on the cleanup type, CleanBlock may record:

  • number of litter pieces removed
  • litter item or category
  • bags collected
  • time volunteered
  • estimated or measured weight
  • before and after photos
  • cleanup municipality
  • county and state geography derived from the cleanup location
  • cleanup type
  • hazards or large items when reported

Users are not required to provide every possible field for every cleanup. Different cleanup types collect different levels of detail.

Personal Impact vs Geographic Impact

Personal impact answers: Who did the cleanup?

Geographic impact answers: Where was the litter removed?

Example

A volunteer lives in Agawam, Massachusetts. They remove:

  • 100 pieces in Agawam
  • 200 pieces in West Springfield

Personal impact: 300 pieces

Geographic impact:

Agawam = 100 pieces

West Springfield = 200 pieces

The cleanup is attributed to where the litter was actually removed, not where the volunteer lives.

What CleanBlock Data Does Not Automatically Mean

  • More pieces removed does not necessarily mean an area has more litter overall.
  • Fewer pieces removed does not necessarily mean an area is cleaner.
  • Volunteer participation varies by location.
  • Not every piece of litter is documented.
  • User-entered information can contain mistakes.
  • Estimated weights are estimates.
  • Community cleanup data is not automatically equivalent to a controlled scientific sampling study.
  • CleanBlock should not be used alone to make conclusions beyond what the data supports.

Transparency Statement

CleanBlock's goal is to make community environmental action easier to document without overstating what the data means.

When data is confirmed, estimated, unresolved, historical, or excluded from a statistic, CleanBlock should say so.

Transparency is more valuable than making the numbers look larger.

Safety & Liability Agreement

Safety Comes First — Always

No cleanup, badge, score, streak, statistic, or community contribution is worth risking your safety. When in doubt, leave the item alone and report it.

Who these rules are for: These rules are for general community participants. If you are a trained, authorized, and equipped professional (such as a hazmat worker, medical waste handler, or law enforcement), follow your training and applicable laws for your work.

Do not touch — leave it and report it: Do not pick up, touch, or closely inspect any of these:

  • Needles, syringes, or any medical sharp
  • Suspected drugs or drug paraphernalia
  • Chemicals or unknown liquids and substances
  • Biological or medical waste
  • Weapons or ammunition
  • Dead animals
  • Items near active homeless encampments
  • Anything that looks, feels, or smells unsafe
  • Anything you cannot clearly identify

If you see one of these items:

  1. Leave it exactly where it is.
  2. Keep other people and animals away when you can do so safely.
  3. Report it through the app or to your local authority.

Do not touch or closely inspect an item just to figure out what it is. If you are unsure, treat it as hazardous and report it.

No credit for risk: CleanBlock Civic will never ask you to pick up a hazardous item to complete a cleanup, earn a badge, increase a score, or add to community statistics. There is no reward for taking a risk.

Trained professionals only: Only people who are trained, authorized, and equipped for a specific type of hazardous material should handle or dispose of it — and only by following applicable laws, regulations, and accepted safety procedures. CleanBlock Civic does not train or certify anyone for this work.

Your responsibility: You participate voluntarily and at your own risk. You are responsible for your own safety, including wearing gloves and visible clothing, working in safe conditions, and following local laws. Do not enter private property without permission. Contact local authorities (police, city services, or 911 in an emergency) for dangerous, illegal, or hazardous situations.

Liability waiver: CleanBlock Civic, its organizers, administrators, and partners are not liable for injuries, accidents, illnesses, property damage, or legal consequences arising from your participation.

CleanBlock documents environmental impact, not just participation. Cleanup counts, locations, weights, and community statistics follow documented data-quality rules.
