All About Water Q&A

What common contaminants should I be aware of in drinking water?

Common contaminants include bacteria (like E.coli), nitrates, lead, arsenic, volatile organic compounds (VOCs), and naturally occurring minerals such as radon and uranium. The EPA sets maximum contaminant levels (MCLs) for many of these substances to protect public health.

Does the City of Warrenville meet all IEPA drinking water testing and regulations?

Yes, the City complies with all testing requirements and regulations set forth by the Illinois Environmental Protection Agency (IEPA). This is based on analysis of the existing data and reports on the quality of drinking water and monitoring procedures in Warrenville indicates that the City of Warrenville complies with all testing requirements and regulations set forth by the Illinois Environmental Protection Agency (IEPA). 

What should I do during a boil-water advisory?

During a boil-water advisory, you should boil your tap water at a rolling boil for at least one minute to kill harmful bacteria and viruses before using it for drinking or cooking purposes. 

Is the water hard in Warrenville?

Yes. Warrenville’s municipal water system relies on wells drilled into this aquifer. The City has four main wells that extract groundwater for public use. The hardness level of the water from these wells is reported to be between 24-26 grains per gallon. This level indicates a significant concentration of hardness minerals.

Do I need a water softener?

 Installing a water softener is highly recommended. These systems work by replacing calcium and magnesium ions with sodium ions, effectively reducing hardness levels. 

What are the benefits of a water softener?

 Installing a water softener offers significant benefits by:

  • Improving skin condition
  • Enhancing cleaning efficiency 
  • Saving money on soaps and detergents
  • Prolonging appliance life through reduced wear from mineral build-up
  • Increasing energy efficiency for heating systems
  • Providing better tasting drinking water that encourages hydration habits
  • Simplifying household cleaning tasks

Why does the City flush the fire hydrants?

Flushing is a part of routine maintenance, and removes rust or metal particles from the hydrant, which can cause corrosion. Hydrant flushing is an important maintenance activity that supports both public health and safety by ensuring high-quality drinking water and reliable fire protection services. 

What is the City's water treatment process?

Warrenville residences receive water from shallow underground wells, which have iron removal systems. The City uses blended phosphates for corrosion control, chlorine for disinfection, and fluoride for dental health.

How do I know if my tap water is safe to drink?

You can determine if your tap water is safe by reviewing your annual Consumer Confidence Report (CCR) provided by the City of Warrenville. 

What is the Consumer Confidence Report (CCR)?

It is annual document that provides essential information about the quality of drinking water supplied by community water systems in the United States. The U.S. Environmental Protection Agency (EPA) mandates that every community water supplier provide this yearly.

What do I check if I have low water pressure?

  1. Check for multiple fixtures running
  2. Inspect main shutoff valve
  3. Look for leaks
  4. Investigate clogged pipes
  5. If you have a water softener, try bypassing the softener

What should I do if I have a rotten egg smell in my water?

The most common odor associated with hot water is a “rotten egg” smell, which is primarily caused by the presence of hydrogen sulfide gas. Below, we will explore the causes of these odors, how they develop, and what you can do to eliminate them.

1. Understanding the source of odors

The foul smell in your hot water typically originates from two main sources:

  • Sulfate-reducing bacteria: These bacteria thrive in warm environments, such as those found in stagnant water heaters. When the water heater remains idle for extended periods, these bacteria can reproduce and produce hydrogen sulfide gas as a by-product, leading to that characteristic rotten egg smell.
  • Deteriorating anode rods: Most traditional tank-type water heaters contain a sacrificial anode rod made of magnesium or aluminum. Over time, this rod corrodes to protect the tank from rusting. However, when it deteriorates too much, it can also contribute to foul odors by reacting with sulfate ions in the water.

2. Identifying the problem

To determine if the odor is coming specifically from your hot water supply:

  • Run both hot and cold taps in your home.
  • If only the hot water has an odor while the cold does not, then the issue lies within your hot water heater.

3. Common causes of hot water odors

  • Bacterial growth: Bacteria can flourish in stagnant conditions within your water heater.
  • Sediment build-up: Hard water can lead to sediment accumulation at the bottom of your tank, providing a breeding ground for bacteria.
  • Chemical reactions: The interaction between certain minerals (like sulfates) and metals (from corroded anode rods) can also produce unpleasant smells.

DIY solutions for eliminating odors

If you find that your hot water smells bad, here are some steps you can take:

1. Flush your water heater:

  • Drain and refill your tank to remove sediment and bacteria.
  • This process involves connecting a garden hose to the drain valve and letting it run until clear.

2. Sanitize with bleach or hydrogen peroxide:

  • After flushing, consider adding bleach or hydrogen peroxide into the tank to kill any remaining bacteria.
  • Allow it to sit for 30 minutes before draining again.

3. Check and replace anode rods:

  • Inspect your anode rod; if it’s significantly corroded, replace it with a new one made of aluminum or zinc instead of magnesium to reduce odors.

4. Increase water temperature:

  • Raising the temperature setting on your heater (to about 140°F) can help minimize bacterial growth but be cautious about scalding risks.
