ELGIN, Elgin's water system, serves 113,911 people. 1 other system also serves parts of Elgin. Each system's results are listed under its own name, never added to ELGIN's. Water quality testing is conducted regularly and reported to the EPA. The latest sample on file for ELGIN is from Aug 2024.
In EPA's 2023โ2026 UCMR 5 testing, ELGIN measured lithium at up to 19.3 ยตg/L, which EPA counts as above its health reference level of 10 ยตg/L. That level is a screening value EPA uses to decide what to study further, not a legal limit, and this result does not change this page's water-quality summary.
