We meet requirements set out by the EPA. Some policies customers should be aware of would be that we complete a chain of custody upon sample drop off and adhere to sampling hold times as well as sample preservation requirements. It may be useful to review our hold times, which indicate how long we have to analyze a sample from the time it is taken, and sampling requirements, such as the correct sample bottle, temperature requirements, and preservatives. We can provide this information in a chart. There may be other policies to review as well, which we can discuss during the consultation process.
