# What does the Contamination-page show?

The Contamination page shows you what is being contaminated, how much it amounts to, and which tenants are involved.

Here, you can:

- view the **contamination rate** and **weight of contaminated waste**, including changes compared with the previous 90 days
- see the number of **disposals flagged for contamination** and how many **tenants with reported contamination** there were during the period
- track **contamination over time**, shown as the proportion of disposals flagged for contamination, either over the past 12 months or since tracking began
- view an exportable table showing **contamination by tenant**—including the number of contaminated disposals, the weight of contaminated waste, and the contamination rate
- see how much of the **sorting rate has been lost due to contamination**: sorted waste streams that have been marked as contaminated and therefore recorded as residual waste, reducing the building’s overall sorting rate
- see how many percentage points the sorting rate could increase by if contamination were eliminated

The Contamination page is the place to go when you want to identify specific tenants who need follow-up or understand how much contamination is actually costing you in terms of your sorting rate.
