On Jan. 1, 2020, we began a new six-month compliance sampling monitoring period in University Park. Compliance samples allow us to measure lead levels in water that has sat stagnant in customers’ pipes for six or more hours and is therefore at a higher risk for lead exposure.
In January, we collected 58 compliance samples from University Park homes and businesses – well above the 40 required by regulation for the entire six-month period – so we could better understand the chemistry in customers’ pipes and track our treatment’s progress.
Moving forward, on an ongoing monthly basis, we will collect additional compliance samples from homes within our existing sampling pool. To keep the public and other stakeholders informed of our progress, all results will be shared on this page by the 10th of each month.
Customers can call 877.987.2782 at any time to request water sampling.
As agreed to with the State, water sampling in University Park is currently suspended due to COVID-19 and medical and government recommendations. We will continue to provide updates as we learn more.
March Data Update
Updated on 04/10/2020
Overall water quality in University Park has improved, but data continue to show that it is critical that impacted customers regularly use their water to fully resolve this situation.
About 62 percent of all compliance-sampled homes are at or below the Environmental Protection Agency’s threshold for lead, 15 micrograms per liter (ug/L), as of March 2020. According to the EPA’s Lead and Copper Rule that regulates drinking water, the treatment is considered effective when 90 percent of sample locations meet that threshold.

The data demonstrate that overall lead levels have improved, but elevated lead levels remain in some homes. Lead concentrations continue to show some variability, which is to be expected as the piping continues to adjust to the treatment.

To help resolve this situation, customers under the advisory should run cold tap water from their kitchen faucets an extra 30 minutes every day, in addition to their regular water use. This will allow us to work together toward the solution and speed up the treatment process.
Water use moves the treatment through the system so it can establish a protective layer inside customers’ home plumbing. The protective layer will stop lead inside customers’ internal plumbing from interacting with water flowing into their homes.
In the same way that painting a room at home sometimes requires several coats of paint, the treatment requires more water flow to fully coat the home’s pipes.
It is important to note that by the end of 2019, 100 percent of samples that were collected from University Park homes after running the tap water for two to three minutes had nearly non-detectable lead levels. This validates that, in addition to helping the treatment work, running the tap water is highly effective at reducing potential lead exposure.
We thank our customers for their continued patience and cooperation.
