How to collect Samples: To take your sample, run your cold tap for five to ten minutes then collect about one cup of water in a plastic baggie (double bag) or clean jar. Keep the water cool until arrival. You can collect the water anytime within one day of the nitrate analysis (if you are going to the local office right after work, you can collect the sample in the morning and keep it cool all day until you arrive).
