Water Quality Reports (CCR)

Iowa Regional Utilities Association (IRUA) believes every member should be able to see where their water comes from and how it performed over the past year. That’s why IRUA publishes yearly water quality reports, also known as Consumer Confidence Reports, for the water systems it serves. This page explains what the reports cover, which systems they include, how to read one, and where to find IRUA’s service line inventories. The reports themselves are listed below.

Why IRUA Shares These Reports

IRUA is a private, not-for-profit association owned by its members. Property owners who receive service are part-owners, and IRUA provides drinking water to its members at cost. Sharing clear, yearly information about your water is part of that relationship. The reports are one more way IRUA keeps members informed and prepared, so you never have to wonder where your water comes from.

What Is a Consumer Confidence Report?

A Consumer Confidence Report, often shortened to CCR, is IRUA’s yearly report on drinking water quality. It’s written for members and gives you a clear, organized look at your water. Each report includes:

Your water sources: A description of the suppliers and plants that provide water to that system.
Results tables: A summary of the water quality testing results from the past year.
Contact information: Who to call with questions about the report.
How to get involved: Information about IRUA’s monthly Board of Directors meetings and how members can address the Board.

Reports are published once a year. Each one covers the previous calendar year, so the reports published in 2026 share data from 2025. When you open a report, check the reporting year first so you know which period it describes.

Which Systems the Reports Cover

IRUA serves a large area, and not every part of it gets water from the same place. That’s why there is more than one report. Look for the report that matches the system serving your property:

IRUA’s main system: Covers water IRUA purchases from regional suppliers, including Newton and Marshalltown, and water produced at IRUA’s own reverse-osmosis treatment plant near Waverly.
Attica/Pershing: This system buys bulk water from Marion County Rural Water, which is supplied by Knoxville Water Works.
Southshore Heights: This system buys its water from Knoxville Water Works.

For the main system, each supplier draws from its own source. Newton’s supply comes from a Jordan well and 21 shallow alluvial wells along the South Skunk River, and it is softened before it reaches IRUA. Marshalltown’s supply comes from the Mississippian aquifer and is softened using a lime soda-ash process. At Waverly, IRUA produces its own supply using reverse osmosis. IRUA’s rural water service delivers treated, softened water at about 6 to 8 grains of hardness.

How to Read Your Report

Water quality reports include some technical terms, but you don’t need a science background to understand them. Here’s a simple way to work through yours:

Confirm the system and year. Make sure the report matches the system that serves your property, and note the calendar year it covers.
Start with the source. Read the section that describes where the water comes from. It tells you which supplier or plant provides water to your system.
Review the results tables. Take the tables one row at a time. Each row covers a single item that was measured during the year.
Read the notes alongside the tables. Any written explanations that go with a table can help you understand the numbers.
Keep it for reference. Save a copy of your report so you can compare it with next year’s edition when it’s published.
Write down your questions. If a term or abbreviation is unfamiliar, make a note of it. We’re happy to walk you through it.

Questions about the main system’s report can go to Mike Wildung, IRUA’s Operations and Distribution Manager, at 641-792-7011. For more about where IRUA’s water comes from and how it’s treated, visit the Water Quality page.

Lead Service Line Inventory

Alongside the yearly reports, IRUA publishes service line inventories, sometimes called lead and copper service line inventories. Here’s what you need to know:

What a service line is: A service line is the pipe that connects a property to the water system. On IRUA’s system, the property owner installs and maintains the service line from the meter pit.
What the inventory is: The inventory lists what service lines are made of. It’s a record of materials, not a water test result.
Which inventories are available: Inventories are posted for Attica/Pershing, Dows, IRUA’s main system, and South Shore.

If the inventory lists your service line as UN or UB, you can help IRUA complete its records by sharing the actual material of your line. Contact IRUA and we’ll show you how to submit that information. Your information helps keep the records accurate and complete.
