Are We Running Out of Water?
The World Wildlife Fund (WWF) reports some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion people find water-scarce at least one month of the year. Why are we running out of water? There is an abundance of water, however, the problem is having access to a supply of potable water, or water that is fit for consumption. Even in countries with adequate water resources, water scarcity is still not uncommon. Water shortages can be caused by collapsed infrastructure, failed distribution systems, pollution, poor management, or other economical factors.

The Flint, Michigan Water Crisis: Seven Years Later
The Flint water crisis began with an overzealous emphasis on the economy. In 2014, declaring a financial emergency, Flint, Michigan Governor Rick Snyder appointed a state of emergency manager to take control of Flint’s finances. The emergency manager was given authority for all things financial. Those outside the water industry may be ignorant to the ramifications of prioritizing the economy over water quality. However, failure to take the necessary actions to ensure acceptable water quality and safety is indefensible.

Investing in the Security of Our Public Water Infrastructure
Have you thought about where your water comes from? What would do without it? You turn the tap and there is fresh, clean, potable water. The only time it may enter your mind is during the inconvenience of a water shortage, with limited lawn watering and car washing, or the occasional boil water advisory. But what happens if the water is gone, or contaminated? You could use a UV water treatment system to disinfect the water coming into your home, but what if the water never reaches the system? As you’re reading through this article, pause and think about life without clean water.

Reducing Lead Exposure Through Drinking Water
There is no safe level of lead in drinking water, but a zero goal, though laudable, is at present an unattainable goal. The policing of lead in drinking water is generally in the hands of the local utility company until testing reveals lead levels higher than 15 ppb (parts per billion) in 10% of the samples collected in the distribution system. This means the action level for remedial action is 15 ppb. The frequency and number of samples collected is determined by the service population of the utility, history of analysis results, and the success of remedial measures, if they prove to be required. Remedial measures may be avoided by implementing some measures as ongoing treatment regimens, whether there is a problem or not. The chief remedial or preventive actions involve implementing and maintaining a corrosion control program to prevent leaching of regulated metals, such as lead and copper, into the product.

UV Disinfection In Wastewater Treatment
An ultraviolet (UV) disinfection system is an effective way to remove microbial contamination in wastewater. The UV disinfection system is part of the tertiary treatment of wastewater and normally follows a filtration process. In the system, microbes are exposed to UV light that destroys their DNA. Destroying these microbes disinfects the water. UV disinfection systems are used in many different applications ranging from the purification of drinking water to wastewater treatment. We will be focusing specifically on wastewater treatment. UV disinfection is a safe and cost-effective wastewater treatment application.
