SILVIS is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 7,473 people from surface water.
As of August 1, 2026, its federal record holds 48 entries between 1977 and 2026, of which 1 health-based item remains open, alongside 1 other open entry.
Of the 48, 27 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 the Public Notice Rule and Revised PN Rule, inorganic chemicals, and the Radionuclides and Revised Rad Rule.

When is SILVIS’s next Consumer Confidence Report due?
- SILVIS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does SILVIS have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 1 open health-based violation for SILVIS, alongside 1 other open item.
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.
