• A contracted water sampler will arrive at the given location on the scheduled time to perform sample collection.
• Prior to the scheduled visit, you must not use the water in your home for at least SIX (6) hours. This allows the water to stagnate in the plumbing system of your home. Do not flush the toilet or get a quick drink of water during this time. Please refrain from using your shower, dishwasher, washer for clothes, automatic ice machine, and yard irrigation system, as well as anything else that may use water.
• We recommend filling a pitcher with water prior to stagnation to use during this period of no water usage.
• If you live in a multi-unit building, it is not necessary to restrict the use of water in other units of your building. Simply ensure you do not use the water in your unit.
• If you accidentally use water, please call (312) 744-8190.
• If you need to reschedule for a different time, please use the website at least 8 hours prior to your visit.
