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 2022, staff collected and analyzed Cary's drinking water
approximately 100,000 times for many substances such as
radioactive, biological, inorganic, volatile organic, or synthetic
organic substances. The table below shows only those substances
that were detected in the water. Unless otherwise noted, the data
presented in the table below is from testing performed from
Jan. 1–Dec. 31, 2022. 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.
