Information About Your Drinking Water
The sources of drinking water (both tap water and bottled water) include
rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels
over the surface of the land or through the ground, it dissolves naturally
occurring minerals and, in some cases, radioactive material, and can pick up
substances resulting from the presence of animals or from human activity.
Drinking water, including bottled water, may reasonably be expected to
contain at least small amounts of some contaminants. The presence of
contaminants does not necessarily indicate that water poses a health risk.
More information about contaminants and potential health effects can be
obtained by calling the USEPA’s Safe Drinking Water Hotline, 1-800-426-
4791.
Natural Contaminants Present in Source Water
Prior to Treatment May Include:
Microbial Contaminants: Such as virus and bacteria, that may come from
sewage treatment plants, septic systems, agricultural livestock operations
and wildlife.
Inorganic Contaminants: Such as salts and metals, that can be naturally
occuring or result from urban stormwater runoff, industrial or domestic
wastewater discharges, oil and gas production, mining or farming.
Pesticides and Herbicides: That may come from a variety of sources such
as agriculture, urban stormwater runoff, and residential uses.
Radioactive contaminants: Can be naturally occuring or be the result of oil
and gas production and mining activities.
Organic Chemical Contaminants: Including synthetic and volatile organic
chemicals, that are byproducts of industrial processes and petroleum
production, and can also come from gasoline stations, urban stormwater
runoff, agricultural application and septic systems.
What Is In My Drinking Water?
Your drinking water is tested by certified professional water system operators
and certified laboratories to ensure its safety. The City of Glendora routinely
tests drinking water from its wells and distribution system pipes for bacterial
and chemical contaminants. The chart in this report shows the average and
range of concentrations of the constituents tested in your drinking water
during year 2024 or from the most recent test. The State allows the City to
monitor for some contaminants less than once per year because the
concentrations of these contaminants do not change frequently. Some of our
data, although representative, are more than one year old. The chart lists all
the contaminants detected in your drinking water that have federal and
state drinking water standards. Detected unregulated contaminants of
interest are also included.
