Need proof of when my dad worked on camp lejeune during the years of the water contamination. He worked with an electrical company doing contract work all around the base.

Question

[Moderation edit] 
 My dad [ Charles Dean Thomas.] worked with an electrical company named Big John Electric Company from 6/25/79 till 8/29/08. I have contacted the electrical company who says they didn't keep their records back then on the computer and so have no records of those contracts. 
 I know he worked on the base for many years but I have no record

 Thank you for posting your question on History Hub! 
 
 According to the Naval Facilities Engineering Command, contract records are temporary records and are disposed of in accordance with the U.S. Navy's Records Schedule. Typically, contract records relating to Facilities Engineering Command are disposed of six years after completion of the contract. For retention periods for Navy Records please reference the Department of the Navy Records Management Program: Records Management Manual SECNAV M-5210.1. 
 
 We hope this assists you with your research!
