RHP professionals perform lead in water testing and create mitigation action plans to minimize exposures at commercial buildings, industrial facilities, residential homes, schools and day cares.

Drinking water supplied in lead pipes can be hazardous to your health. If the water supply to a building or home passes through lead pipes or an illegal lead solder to joint pipes, the lead can dissolve into the drinking water. Lead is a dangerous metal that has been shown to cause serious injury if it is allowed to build up in the body.

Consulting on Safe Drinking Water Act / U.S. EPA's Lead and Copper Rule

The EPA’s Lead and Copper rule requires a system to monitor drinking water at commercial taps such as drinking fountains. If lead concentrations exceed an action level of 15ppb or copper concentrations exceed an action level of 1.3ppm in more than 10% of taps sampled, the system must undertake a number of additional actions to control corrosion. If the action level for lead is exceeded, the system must also inform the public about steps they should take to protect their health and may have to replace lead service lines under their control.

The Safe Drinking Water Act (SDWA) was established to protect the quality of drinking water in the U.S. This law focuses on all waters actually or potentially designed for drinking use, whether from above ground or underground sources.

Testing Well Water

The Environmental Protection Agency (EPA) recommends testing well water at least once a year for bacteria and nitrate. Additionally, the EPA recommends testing your well water for other contaminants including volatile organic chemicals (VOCs), pesticides, radium and other contaminants.

Lead in Water Testing for Illinois Department of Public Health (IDPH) Requirements

To protect Illinois children from possible exposure to lead in drinking water, the Illinois Public Act (99-0922) requires schools to sample for lead contamination in water. The Act requires the oldest school buildings, those built before January 1, 1987, to have completed water testing by the end of 2017. Schools built between January 2, 1987 and January 1, 2000 must have completed testing by the end of 2018. The Act requires parents and guardians of students be notified of lead results greater than or equal to 5 parts per billion (ppb). 

RHP experts will come to your commercial and residential day care to take samples, bring the samples to an accredited laboratory for testing, and provide a report of the findings. Should the test results show the lead in water is 2.01ppd or higher, RHP can design a written mitigation plan to submit to your DCFS representative and assist with mitigation strategies.

Illinois legislation requires lead testing of water for all day care centers, day care homes, and group day care homes that serve children ages birth to 6 years old that were constructed on or before January 1, 2000.
