In EPA's 2023–2026 UCMR 5 testing, COACHELLA VWD: COVE COMMUNITY measured lithium at up to 17.7 µg/L, which EPA counts as above its health reference level of 10 µg/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.
