Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper.
EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Shakopee’s water between Jan 2025 and Aug 2025. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFBS4.7 pptFound in 4 of 26 samples · highest resultNo federal limit in force for this one
- Lithium21.7 ppbFound in 23 of 26 samples · highest resultAbove EPA’s health reference level of 10 ppb (a guide, not a legal limit)
Source: EPA UCMR 5 occurrence data. The highest single result is shown; one high sample doesn’t mean every glass is that high.
What you can do
Nothing here is an emergency notice: if the district has a violation, it must tell customers directly. If you’d like to lower these at your tap, these are the treatments that remove them, and the catalog shows the models certified for each. Ranking is by certified removal; commissions never change the order.
Lead
Found: Copper, Lead
What removes it: Reverse osmosis or Certified carbon block or RO.
PFAS ("forever chemicals")
Found: PFOA (a PFAS), PFOS (a PFAS)
What removes it: Reverse osmosis.
Radium and uranium
Found: Radium (combined 226 + 228)
What removes it: Reverse osmosis.
