Riverdale City Water System
EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Utah Department of Environmental Quality, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2019 - March 2019), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
- Weber County County, Utah
- Serves: 8,500
- Data available: 2012—2017
- Source: Purchased surface water
Legal ≠ Safe
EWG Health Guidelines fill the gap in outdated government standards.
The federal government’s legal limits are not health-protective. The EPA has not set a new tap water standard in almost 20 years, and some standards are more than 40 years old.
NitratePotential Effect: cancer5x EWG'S HEALTH GUIDELINE
Nitrate, a fertilizer chemical, frequently contaminates drinking water due to agricultural and urban runoff, and discharges from municipal wastewater treatment plants and septic tanks. Excessive nitrate in water can cause oxygen deprivation in infants and increase the risk of cancer. Click here to read more about nitrate.
Nitrate was found at 5 times above EWG's Health Guideline.
EWG Health Guideline
ppm = parts per million
The EWG Health Guideline of 0.14 ppm for nitrate was defined by EWG . This health guideline protects against cancer and harm to fetal growth and development.

Radium, combined (-226 & -228)Potential Effect: cancer9x EWG'S HEALTH GUIDELINE
Radium, combined (-226 & -228)more about
Radium is a radioactive element that causes bone cancer and other cancers. It can occur naturally in groundwater, and oil and gas extraction activities such as hydraulic fracturing can elevate concentrations.
Radium, combined (-226 & -228) was found at 9 times above EWG's Health Guideline.
EWG Health Guideline
pCi/L = picocuries per liter
Health RisksEWG applied the health guideline of 0.05 pCi/L, defined by the California Office of Environmental Health Hazard Assessment as a public health goal for radium-226, to radium-226 and radium-228 combined. This health guideline protects against cancer.
Includes chemicals detected in 2015-2017 for which annual utility averages exceeded an EWG-selected health guideline established by a federal or state public health authority; radiological contaminants detected between 2012 and 2017.
Di(2-ethylhexyl) phthalatemore about
Di(2-ethylhexyl) phthalate, or DEHP, is a softener added to PVC plastics. Phthalates are hormone disruptors that target the male reproductive system.
How your levels compare
EWG Health Guideline
ppb = parts per billion
The EWG Health Guideline of 3 ppb for di(2-ethylhexyl) phthalate was defined by the Environmental Protection Agency as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.
Runoff & Sprawl
Includes chemicals detected in 2015-2017 for which annual utility averages were lower than an EWG-selected health guideline established by a federal or state public health authori.
