What we know

Alliance Environmental Group, LLC, a California-based provider of environmental and construction support services, publicly reported a data security incident on September 15, 2026.

The compromised information includes Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, and Telephone Number.

If you received a notification from Alliance Environmental Group, it is crucial to take immediate steps. We recommend carefully reviewing your bank statements, credit card accounts, and explanations of benefits for any suspicious activity.

Under California law, companies like Alliance Environmental Group have a legal duty to protect the sensitive personal information they collect. This includes implementing reasonable security measures to prevent unauthorized access.

Receiving a breach notification may establish your standing to pursue legal action.

Affected individuals are not required to demonstrate actual financial losses to explore their legal options. The increased risk of future harm from having sensitive data exposed can be a sufficient basis for legal claims.
