EACH YEAR, THE STATE CERTIFIED L ABORATORY
AT THE CARY/APEX WATER TREATMENT FACILIT Y
PERFORMS EXTENSIVE TESTING TO ENSURE THE
SAFET Y OF YOUR DRINKING WATER.
In 2023, staff collected and analyzed Cary's drinking water
approximately 90,000 times for many substances such as
radioactive, biological, inorganic, volatile organic, or synthetic
organic substances. The following tables show only those
substances that were detected in the water. Unless otherwise
noted, the data presented is from testing performed from
Jan. 1–Dec. 31, 2023.
The EPA and the State allow monitoring for certain substances less
than once per year because the concentrations of these substances
are not expected to vary significantly from year to year. In these
cases, the most recent sample results are included, along with the
year in which the sample was taken. Some of the data, though
representative of the water quality, is more than one year old.
