Water and Wastewater Systems Sector

Welcome to another insightful week of Chem-Sect. This week, I will be discussing the Water and Wastewater Systems Sector and and how it is associated with it and how it is an integral part of our environment.

Overview of this Sector
Did you know that there are approximately 153,000 public drinking water systems and more than 16,000 publicly owned wastewater treatment systems in the United States? If you said, “yes,” then you are correct. Fact. More than 80% of the U.S. population receives their drinkable water from these water systems. Additionally, approximately 75% of the U.S. population has its sanitary sewerage treated by these wastewater systems.
 
Consuming safe drinking water is paramount to everyone. Fresh, clean, and healthy water is a prerequisite for protecting public health and the well-being of a community. It is also important that properly treated wastewater is vital in preventing diseases as well as protecting the environment. In doing so, it ensures that the supply of drinking water and wastewater treatment services remain essential to everyday life and to our Nation’s economy.
 
Water Facts

· It takes approximately 33 ounces of water to create a single sheet of paper.

· It takes about the same amount of water to irrigate one calorie worth of food
· While 71% of our earth is blanketed with water, approximately 3.5% is fresh water
· Of that fresh water, only about 25% is accessible – simply put, only 0.75% of the world’s water is fresh and accessible for use.
 
The Safe Drinking Water Act (SDWA) The SDWA requires the Environmental Protection Agency (EPA) to establish and enforce standards that public drinking water systems must follow. The EPA delegates primary enforcement responsibility (primacy) for public water systems to states and Indian Tribes if they meet certain requirements. Primary standards and treatment techniques by the EPA protect public health by regulating the levels of contaminants in drinking water through drinking water regulations.

Water in the Environment

The importance of water to ecosystems, living resources, and human welfare is widely appreciated. However, much is yet to be understood about the impacts of human activities on water quality and its global distribution. There is a continuous need to develop appropriate, efficient, and sustainable approaches like technology to maintain water quantity and quality for the environment.

At the same time, water ecosystems must also meet the needs for food security and sanitation as population grows. Another important factor is to understand the relationship between energy consumption and food production as it relates to environmental water quantity and quality.

Common Questions
Here are just a few of the most commonly asked questions about your drinking water…

Q. Is bottled water safer than tap water?
A. It depends. According to the EPA, bottled water is not necessarily safer than your tap water. However, some bottled water is treated more than tap water while some is treated less or not treated at all. Bottled water costs much more than tap water based on a per-gallon ratio. The EPA sets the standards for drinking water provided by public water systems. Bottled water and tap water are both safe to drink if they meet these EPA standards.

Q. How long can bottled water be stored?
A. Currently, the FDA has not established a shelf life for bottled water. However, it can be stored indefinitely if it is kept in the proper environment – in a dry place out of direct sunlight, stored at room temperature or cooler, and kept away from toxic chemicals such as cleaning agents, solvents, and gasoline.
 
Q. How much does it cost to treat and deliver drinking water?
A. It costs less for our drinking water than it does for most other goods and services such as cable television, telephone service, and electricity.  On average, tap water costs are slightly more than $2 per 1,000 gallons although the costs tend to be lower for large water systems.
 
Q. Can I tell if my drinking water is okay by just looking at it, tasting it, or smelling it?
A. No. None of the chemicals or microbes that could make you sick can be seen, tasted, or smelled.
