Regulatory agencies collect many samples and much data on potentially polluting sites, sometimes not knowing which samples, data, and reports could become part of a legal or quasi-legal proceeding.  Phoslab Environmental Services follows precise measures set forth by governing agencies for legal custody of sample and data procedures.

For purposes of litigation, regulatory agencies must be able to prove the legal integrity of all samples and data introduced as evidence. This means it is necessary to have an accurate written record to track the possession, handling, and location of samples and data from collection through reporting. Verification of who has possessed the samples and data and where the samples have been is easier if you follow chain-of-custody procedures.

Many times there is no way to know in advance which samples and data may be involved in litigation, you should always follow chain-of-custody procedures whenever samples and data are collected, transferred, stored, analyzed, or destroyed.  A secure chain of custody, combined with the use of proper analytical methods and techniques provided by Phoslab Environmental Services, is necessary for a legally defensible reporting of samples.
