Nitrate at Colonial Manor Water System

Florida · system FL6510355 · serves 1,794 people · purchased water

This system purchases its water; the band reflects the supplier's most recent reported result within a rolling three-year window. The three-year range below is the supplier's, not this system's own sampling. The water comes from Pcud-Pasco County Regional Pws (FL6511361).

A single reading is not a complete account of what a household drinks, so the three-year range and the number of tests behind it are shown too — a reading backed by many tests over three years is a fuller picture than one from a single sample.

Where this ranks

The water this system purchases sits in the top 20% nationally. Systems reporting less serve about 80% of everyone on NitrateSmart's tracked supply; the other about 20% are on systems reporting the same or more. That compares what systems reported, not what comes out of any one tap.

What "Human impact likely" means

Nitrate here is low, but a little above natural background[1] — enough to suggest that fertilizer, manure, a septic system, or wastewater has reached the source. This is a statement about where the nitrate came from, not about harm.

The bands describe how strongly human activity, read from nitrate, has marked a water source — they are not a safety verdict. More on what the numbers mean and where nitrate comes from.
