Drinking Water Results for Academic Buildings

 

The values in the results table have the units of parts of lead per billion parts of water (ppb). This is equivalent to micrograms of lead per liter of drinking water (ug/l).

Avocet, the independent testing laboratory used for testing, reports results in milligrams of lead per liter of water (mg/l). Milligrams per liter are equivalent to parts per million (ppm).

There are 1000 parts per billion in one part per million. The first result received for the fifth floor of Arntzen is shown below in different units which all represent the same concentration of lead in the water:

0.028 mg/l
0.028 ppm
28 ug/l
