PLEASE READ CAREFULLY
LEAD AND COPPER SAMPLING REQUIREMENTS
- Samples MUST be collected at different locations, unless a system does not have enough different sites to fulfill their sampling requirement
- Samples MUST be collected from sites where water may be consumed (drinking fountains, kitchen sinks, bathroom sinks, break rooms, etc.)
- ALL samples MUST have a minimum 6-hour stand time (water must sit in the pipes for a minimum of 6 hours before sample is collected). NOTE: If you need to collect multiple samples from a location (i.e. you do not have enough different sites), DO NOT COLLECT SAMPLES ONE AFTER THE OTHER- THERE MUST BE AT LEAST 6 HOURS STAND TIME BETWEEN SAMPLES COLLECTED AT THE SAME SITE.
- Lead and copper samples are 1 ST DRAW samples. DO NOT run the water before collecting the sample. Collect the “1 st draw” of water when you turn on the faucet.
- DO NOT COLLECT samples from vacant apartments, trailers, etc.
- Samples MUST be collected during the months of JUNE, JULY, AUGUST or SEPTEMBER if you are on an annual or 3-year monitoring schedule, unless you have an approved modified schedule.
