This risk is in addition to those cancer cases that would normally occur in an unexposed population of one million people. Note, this is different from an annual cancer risk which does not assume a lifetime exposure.

  • "Bad" ozone occurs in the earth's lower atmosphere and is the primary constituent of smog. Sunlight and hot weather cause harmful concentrations of ozone in the air, causing high levels in the summer.
  • "Good" ozone occurs naturally in the stratosphere, approximately 10 to 30 miles above the earth's surface, and forms a layer that protects life on earth from the sun's harmful rays.

The size of particles is directly linked to their potential for causing health problems. Unless otherwise specified, the measure of particulate matter refers to particles both greater than and less than 10 micrometers in diameter. Particles that are 10 micrometers in diameter or smaller (PM10) generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects. 

PARTICULATE MATTER 10 - "Particulate matter" is also known as particle pollution or PM. PM10 refers particularly to particles that are 10 micrometers in diameter or smaller (PM10). Particles of this size generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects. See also Particulate Matter.

PERCENTILE-One approach for grouping numbers. To create a percentile, the whole group of numbers is divided into 100 smaller groups with an equal number of items in each group. For example, if there are 100 numbers, each group has only 1 number in it. Another example is if there are 300 numbers, each group as 3 numbers in it. A particular percentile, for example the 5th percentile, means 5% of the numbers are below it and the remaining 95% of the numbers are above it. 

PERINATAL PERIOD- The perinatal period commences at 28 completed weeks of gestation and ends seven completed days after birth.

PUBLIC WATER USE INDEX (%)-Population served by public water systems divided by county population (Census 2000 estimate) multiplied by 100. This measure is available only by county. It estimates the percentage of the county population served by public water systems. Note, that some water systems (for example, those in Milwaukee county) serve populations of neighboring counties. This is therefore a very rough estimate. 

PUBLIC WATER SYSTEM-A system that provides piped water for human consumption to at least 15 service connections or regularly serves at least 25 individuals.
