Mission Statement
The Oneida Nation Utilities Department provides safe drinking water and environmentally safe wastewater treatment for the Oneida Nation.
Annual Water Reports
Site 1 & 2 2025 | Ridgeland 2025 | Sandhill 2025 | Hillside 2025 |
Each year, the Oneida Water Utility provides its customers with an annual Water Quality Report to provide you a snapshot of Oneida’s drinking water quality and letting you know how the Utility works to stay in compliance with drinking water standards. The Oneida Water Utility is part of the Oneida Division of Public Works. The same team who works on your drinking water also works with the Oneida Wastewater Facility. The Oneida Utilities Team provides safe drinking water and environmentally safe wastewater treatment for the Oneida Nation’s citizens and utility customers through routine testing, maintenance, environmental advocacy and continuous education.
WHERE DOES OUR WATER COME FROM
Ground water is pumped up to a pump house where it is treated with chlorine. The chlorine disinfects the water from various viruses and bacteria that may be in the ground water – the chlorine protects against microbial contamination of the drinking water and keeps the drinking water clear. Chlorine levels are monitored daily and tested weekly to ensure healthy treatment of the water.
HEALTH INFORMATION
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800) 426-4791.
DETECTED CONTAMINANTS
Your water was tested for many contaminants last year. Most water monitoring testing occurs every three (3) years, except for annual reporting for nitrates and trihalomethanes, monthly reporting for total coliform bacteria, and weekly residual chlorine reporting. This report lists only those contaminants which were detected in your water and have enforceable standards assigned to them. Enforceable standards consider safe levels for human consumption for various contaminants; the standards could be in the form of either a Health Advisory Level (HAL) or a Secondary Maximum Contaminant Level (SMCL), or both. Health Advisory Levels identify at which concentration levels contaminants in drinking water present health risks. Secondary Maximum Contaminant Levels are levels that do not present health concerns but may pose aesthetic problems such as objectionable taste, odor or color.
The reports listed above contain tables that list contaminants which were detected in your water and that have either a Health Advisory Level (HAL) or a Secondary Maximum Contaminant Level (SMCL), or both. Test results that were “negative” or showed “no detected levels” of contaminants are not reported in these tables. If the contaminant was not monitored last year, but was detected within the past 5 years, it will appear in the tables on the next page along with the sample date.

Public Notice
Public Notice of Monitoring Violation
Lead and Copper Monitoring Violation – Annual Notice
Public Water System Site 1 – Oneida Nation
PWSID: 055295703
Violation Information
- Violation Type: Lead and Copper Monitoring Violation
- Violation Period: January 1, 2024 – June 30, 2024
- Date of Distribution: October 10, 2025
IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Lead and Copper Monitoring Requirements Not Met for January–June 2024
Our water system is required to monitor drinking water for lead and copper on a regular schedule to ensure your water meets federal and state drinking water standards. During the January through June 2024 monitoring period, we did collect lead and copper samples; however, the results were received after the required monitoring window had closed. Because the results were not submitted within the required timeframe, the monitoring period is considered a violation.
What Should I Do?
- You do not need to use an alternative water supply (such as bottled water).
- This is not an emergency. If there had been an immediate risk to public health, you would have been notified right away.
- There is no evidence at this time that your water is unsafe.
What Happened? What is Being Done?
Lead and copper monitoring is required to protect public health, especially for vulnerable populations such as children and pregnant women. The required lead and copper samples were not collected during the January–June 2024 monitoring period.
To correct this issue, we have:
• Updated and submitted our lead and copper sampling plan to the Wisconsin DNR.
• Completed monitoring during the 2025 monitoring period.
• Strengthened internal tracking and scheduling to ensure all future monitoring deadlines are met.
• Provided additional staff training and implemented compliance calendar reminders.
We are committed to meeting all future monitoring and reporting requirements to ensure safe drinking water for our community.
Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
