Action plan
What to do with this Cucamonga Valley Water District notice
These steps are drawn from the public filing facts above. They describe the public record; your own letter is the source of truth for the deadlines, offers, and information that apply to you. No step here assumes that Cucamonga Valley Water District offers monitoring, credit protection, or compensation.
Save your letter and its key dates
Keep the original notice, envelope, and any emails together in a safe place. Note every date the letter lists, such as the incident date, any enrollment deadline, or a response cutoff. For context, The public filing reports an incident date of August 15, 2024, and a public notice was reported on June 30, 2025. The dates printed on your own letter are the ones that apply to you.
Review the information categories involved
The public filing identifies name, service address, social security number, driver's license number, financial account information, billing history, account number, and contact information as information that may be involved. Compare this with the data section of your own letter and note exactly which of your information is listed. Because the identified categories may include sensitive details, take the protective steps below seriously.
Verify any monitoring offer before enrolling
Your own letter, not the public filing, will state whether free credit or identity monitoring is offered to you, what it covers, and its enrollment deadline. Before using any link, phone number, or enrollment code in the notice, confirm the letter is genuine by contacting the company through a website or statement you already trust.
Protect your accounts and credit
Because the filing identifies information that may include sensitive details, consider placing a free security freeze with each major credit bureau and watch relevant financial and account activity for anything unfamiliar. A freeze is free and does not affect your existing accounts.
