Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper.
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.
Sediment or cloudy water
Found: Manganese
What removes it: Oxidation filter.
Radium and uranium
Found: Radium (combined 226 + 228), Radium-228
What removes it: Reverse osmosis.
