WATER
QUALITY REPORT
2023

OGDEN CITY 2022 WATER QUALITY REPORT
Ogden City is pleased to present to you this year’s Annual Drinking Water
Quality Report, also known as the Consumer Confidence Report. The purpose
of this report is to inform you of the quality of water and services we deliver to
you every day. The City's goal is to provide you with a safe and dependable
supply of drinking water. The City wants you to understand the efforts made
to continually improve the water treatment process and protect our water
resources. Ogden City is committed to ensuring the quality of your water.
WHERE DOES MY WATER COME FROM?
Ogden City customers receive water from three main sources: groundwater
from wells, surface water drawn from Pineview Reservoir and Wheeler Creek,
and treated water purchased from Weber Basin Water Conservancy District
(WBWCD). WBWCD's water is a combination of treated ground and surface
water from wells and the Weber River.
DRINKING WATER SOURCE PROTECTION PLANS
Ogden City has completed a Drinking Water Source Protection Plan (DWSPP)
for each of its water sources. Each DWSPP identifies the area from which each
water source receives water. The DWSPP assesses potential contamination
threats to the sources within these areas. The DWSPP outlines management
programs to help limit existing and future potential sources of contamination.
Report illegal dumping of oil, fuel, paint & other hazardous materials into
the storm system to: Ogden City Operations 1-801-629-8271
(After hours, call 911)
Vehicles should be washed at a commercial car wash. Vehicles can be
washed on the lawn with biodegradable soap to reduce wash water flows
to the storm drain system.
Recycle Oil - pour waste oil into an unbreakable container (plastic milk
jug), seal and label. Call 1-801-399-8803. Recycling used oil could reduce
national petroleum imports by 25.5 million barrels per year! Do not mix
other materials with oil.
OUR CURRENT STORM WATER MANAGEMENT PROGRAM CONSISTS OF
THE FOLLOWING SIX CONTROL MEASURES:
•Public education and outreach
•Public participation/involvement
•Illicit discharge detection and elimination
•Construction site runoff control
•Post-construction runoff control
•Pollution prevention/good housekeeping
WHERE TO TAKE HAZARDOUS HOUSEHOLD WASTE
There is a household hazardous waste facility located at the Weber
County Solid Waste Facility at 867 West Wilson Lane. Oil, antifreeze, and
paint are accepted. Weber County homeowners can bring their household
hazardous waste to the facility. Call 1-801-399-8803 for more information.
Storm water flows through storm drains directly to local creeks and rivers with NO TREATMENT.
Transportation of Hazardous Materials Along Roadways —
Accidents along highways and other major roads could lead to spills of
hazardous materials and lead to contamination.
Industrial, Commercial, Automotive, Marine, and Equipment Maintenance –
Companies store and use various products and materials that can
contaminate water sources. These contaminants may include acids,
solvents, oils, gasoline, diesel fuel, etc.
Rural Residential Areas – Failing household septic systems can discharge
bacteria and viral pathogens directly into the ground. Fuels, fertilizers, and
pesticides that are used and stored in residential areas are also discharge
risks. These discharges may eventually enter water sources.
Agricultural Activities - Runoff containing fertilizers, herbicides, and
pesticides, applied to croplands, could enter water sources. Runoff
containing bacteria and viruses from animal wastes, from pastures or
animal farms, also has the potential to enter water sources.
Mineral Production - Tunnels or stripped land from mining operations could
lead to higher acidity and/or sediment loads in water sources.
Camping Areas and Other Recreational Activities - Camping wastes from
and fuels used for recreational vehicles have the potential to spill and
contaminate water sources.
Sewage Treatment Facilities - Untreated sewage could discharge directly
into water sources during emergency conditions.
Underground Fuel Storage – Leaking fuel from underground storage tanks
may enter groundwater and eventually reach surface water sources.
A copy of these plans is available for purchase from the
utility billing office. The State Division of Drinking Water
also has copies on file. Possible sources of contamination
are listed below:
STORM WATER POLLUTION PREVENTION: IT IS UP TO US!
Storm water flows through storm drains directly to local creeks and rivers
with NO TREATMENT. Natural and chemical contaminants introduced by
humans can negatively affect water quality.
What are some types of contaminants that might reach our rivers and
streams?
Contaminants resulting from unwise landscaping practices, such
as over applying or overwatering, might include dirt, leaves, grass
clippings, fertilizers, herbicides, and pesticides.
Chemicals from household products from washing your car, painting,
or household cleaners.
Toxins such as oil or antifreeze that may leak from your car.
Did you know that one pint of oil can produce a one-acre slick on a water
surface and can contaminate 250,000 gallons of water?
WHAT CAN YOU DO TO PREVENT STORM WATER POLLUTION?
•Never use the gutter or storm drain system for disposal of household
hazardous waste. If you wouldn’t drink it, don’t dump it.
•Store toxic products and chemicals indoors or in a shed or storage
cabinet.
•Take unwanted hazardous materials and containers to the household
hazardous waste disposal facility.
•Do not wash tools and equipment in driveways, gutters or drainage
ways. Wash over grassed or soil areas where wash water will not
reach the street.
•Inspect and maintain vehicles to reduce leakage of fluids.
•Reduce automotive emissions through regular maintenance and by
limiting vehicle usage.
•Clean up spills with kitty litter or absorbent material and let dry. Dispose
of cleanup as solid waste.
CONTAMINANTS THAT MAY BE PRESENT IN SOURCE WATER INCLUDE:
Microbes - Microbial contaminants (viruses, bacteria, etc.) that may come
from sewage treatment plants, septic systems, agricultural livestock
operations, and wildlife.
Metals - Inorganic contaminants (salts, metals, etc.) that can be naturally
occurring or result from urban storm water runoff, industrial or domestic
wastewater discharges, oil and gas production, mining, or farming.
Chemicals - Pesticides and herbicides that may come from a variety of
sources such as agriculture, urban storm water runoff, and residential uses.
Organics - Organic chemical contaminants (synthetic and volatile organic
chemicals) that are byproducts of industrial processes and petroleum
production. Organic chemicals can also originate from gas stations, urban
storm water runoff, and septic systems.
Radiological - Radioactive contaminants that can be naturally occurring or be
the result of oil and gas production and mining activities. In order to ensure
that tap water is safe to drink, EPA prescribes regulations that limit the
amount of certain contaminants in water provided by public water systems.
FDA regulations also establish limits for contaminants in bottled water, which
must provide the same protection for public health.
“AS A CERTIFIED MICROBIOLOGICAL LABORATORY, OUR MISSION IS TO ENSURE THAT OUR CUSTOMERS
RECEIVE THE HIGHEST QUALITY OF ACCURACY AND SERVICE”.
Ogden City has surveyed many industrial, commercial, and
institutional facilities in its service area for cross-connections. The
City reduces the likelihood of cross-contamination by requiring
water customers to install backflow assemblies on these
cross-connections. Ogden City requires all water customers to
have their backflow assemblies tested annually by a certified
backflow tester. This assures the assembly is providing maximum
protection.
If you have any questions regarding cross-connections, please
contact us at 801-629-8384 or 801-629-8317. For more
information regarding cross-connections, please visit the Ogden
City website http://www.ogdenwater.com/WaterQuality
Backflow preventers are designed to prevent undesired
liquid from flowing backwards into your/our drinking water.
Example of Backsiphonage due to a break in the water main.
LEAD IN DRINKING WATER
Elevated levels of lead can cause serious health problems, especially for
pregnant women and young children. Lead in drinking water generally comes
from materials and components associated with service lines and home
plumbing. Ogden City is responsible for providing high quality drinking water,
but cannot control the variety of materials used in private plumbing
components.
When water has been sitting for several hours, residents can minimize the
potential for lead exposure by flushing their tap for thirty seconds to two
minutes before using water for drinking or cooking. There are independent
laboratories that can test home drinking water (for a fee).
Information regarding lead in drinking water, testing methods, and steps that
homeowners can take to minimize lead exposure can be found through the Safe
Drinking Water Hotline [phone] or at http://www.epa.gov/safewater/lead.
DO I NEED TO TAKE SPECIAL PRECAUTIONS?
Some people may be especially vulnerable to contaminants in drinking water.
Immunocompromised people undergoing chemotherapy, people who have
undergone organ transplants, people with HIV/AIDS or other immune system
disorders, elderly people, and infants can be particularly at risk from infections.
These people should seek advice about drinking water from their health care
providers.
CONTAMINATION FROM CROSS-CONNECTIONS
Unprotected cross-connections are a major concern and can contaminate
drinking water distribution lines. A cross-connection is any point where a
drinking water line connects to a system containing chemicals or water
sources of questionable quality (i.e. air-conditioning, fire sprinklers, irrigation
systems, etc.).
Cross-contamination occurs in two main ways:
1.Cross-contamination can occur when system equipment (booster pumps,
boilers, etc.) increases private water system pressure to higher than that
of the City's water supply line. This situation is known as backpressure.
2.Cross-contamination can also occur when the pressure in the City’s water
supply line drops. This can occur due to a water main break or heavy water
demand. The drop in pressure can cause contaminants to be siphoned
from the private plumbing system into the City’s water supply. This
situation is known as backsiphonage.
Outside water taps and garden hoses are the most common residential cross
-connections. The garden hose creates a hazard when submerged in a
swimming pool or when attached to a chemical sprayer for weed killing or
fertilization. Fertilizers, cesspools, or garden chemicals can contaminate
garden hoses that are left lying on the ground. Improperly installed valves in
your toilet can also be a source of cross-contamination.
Cross-connections jeopardize culinary water supplies unless appropriate
valves are installed on them. These special valves are called backflow
prevention assemblies. These assemblies must be regularly tested and
maintained.
