Testing for Lead & Copper in Drinking Water

The NJ Safe Drinking Water Act requires the NJ Department of Environmental Protection to regulate water provided by Public Water Systems. Schools K-12 including daycare and early learning facilities are required to test lead and copper levels periodically. Lead and copper contamination can occur from the use of lead and copper piping, lead-based solder, brass and chrome-plated faucets and pipe fittings. 

Action levels, as defined by the NJDEP, express a health or physical hazard. They indicate the level of a toxic substance or activity that requires medical surveillance, increased industrial hygiene monitoring, or biological monitoring. If the concentration of lead exceeds the action level of 15 parts per billion or exceeds a copper concentration of 1300 parts per billion, the facility must undertake additional actions to control corrosion and contamination. Of course, any level of contamination is considered to be a hazard.

iATL performs high quality analysis of metals in drinking water through US EPA 200.9 method of Atomic Absorption Spectroscopy (AAS). For more information about NJ drinking water requirements for your organization, please visit: NJ.gov 


Suggested Sampling Instructions:

  1. Water must be settled and unused at your facility for a minimum of 8 hours before taking the samples.
  2. Fill one 250 ml water bottle at each drinking water station in your facility. Water bottles may be provided by iATL at a small cost. Please refer to official state sampling requirements on whether one or two draws are to be taken at each station.
  3. Label each bottle with the station that the sample was taken from and log it on the Chain of Custody form.
  4. Once the samples are taken at each station, seal the bottles well and reinforce the bottle caps with tape to ensure there will be no leaks in transit. 
  5. Please place all paperwork in a sealed Ziploc bag to keep forms out of harm’s way!
  6. Package and ship the samples to us or drop them off at our laboratory at 9000 Commerce Parkway B, Mt. Laurel, NJ 08054 for analysis and reporting.
  7. Results of the sample analysis will be available via email or through iTRACC on our iATL website.
