The City of Lakeland system serves 193,297 people at 5 of 15 above guideline, which is close to the county's 6.0 average. But Lakeland sits inside a county of 152 systems and 646,179 residents, much of it agricultural land where private wells are common. Polk's worst reported system reaches 9. Between city supply, small utilities and private wells, what arrives at a Lakeland tap varies more than one county number can convey.
What this does and does not mean
EWG's health guidelines are stricter than federal EPA limits, so water that exceeds them is usually still legal to serve. The dataset reports how many contaminants were detected above guideline, not which ones — the only way to know what is in the water at your tap is to test it there.
