LOCKPORT is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 23,100 people from groundwater.

As of August 1, 2026, its federal record holds 66 entries between 1977 and 2025, of which 1 remains open; none are health-based.

Of the 66, 51 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves synthetic organic chemicals, the Radionuclides and Revised Rad Rule, and the Total Coliform Rules.

Common questions

Is LOCKPORT required to publish a Consumer Confidence Report?

When is LOCKPORT’s next Consumer Confidence Report due?

LOCKPORT’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does LOCKPORT have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show 1 item for LOCKPORT that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
