The plan is an innovative solution that will remove the primary source of lead within Denver Water’s system, while avoiding the use of orthophosphate that can further exacerbate nutrient pollution problems in rivers, streams, and oceans.
Wildfire is a natural part of many ecosystems, but recently these fires have become more severe, burning more acres and causing destruction in the western parts of the United States. Recently, U.S. EPA researchers have begun to look at the impact of these fires on our water supply, the natural resource we depend on for drinking, irrigation, fishing, and recreation.
Harmful algal blooms are a significant concern for many communities across the U.S. These blooms occur when cyanobacteria grow out of control in fresh and marine waters, often because of excess phosphorus and nitrogen from stormwater runoff and other sources such as fertilizers entering the water.
While septic systems are a viable and undeniably popular choice for wastewater treatment, they are ultimately only as reliable as their upkeep. Can we trust the technology and the human element to protect our waterways from pollution, or is it time to search for better solutions?

The gas detection camera technique has a wide range of potential uses in the petrochemical industry, all of which have positive benefits for the owner of the plant. It is an accepted Alternate Work Practice in the Method 21 leak detection procedure and has clear time and cost benefits over the conventional VOC meter or sniffer method. Although limited to a certain extent by environmental conditions, the camera has proven many times that it can identify leaks at some distance thereby reducing the cost of surveys by removing the requirement to provide access to every potential leak path.
More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but some volcanic islands — like Grenada and St. Lucia — are well forested and provide significant water catchment to support spring water and surface water. But, as populations, agriculture, and industry grow, desalination is becoming more attractive as a water source throughout the entire region.
The nexus of operations and asset management is coming as the water industry continues its digital transformation. Ongoing asset performance management informed by near-real-time data empowers a streamlined view of which assets are nearing the end of their useful lives, and which are operating at optimal efficiency. Read more to see how better data leads to better asset management for utilities of any size.
While more prevalent in certain states, 1,4-dioxane has been detected in the groundwater sources of public water systems across the country. This synthetic chemical has been deemed hazardous to humans by the U.S. EPA and could potentially impact tens of millions of people. The upside is that municipalities have options to address the contaminant. Using a trusted partner can allow them to optimize technologies and process flow to achieve the best results at the lowest cost.
Effective control of the microbiological environment in water distribution systems is one of the biggest keys to providing a healthy product. When it comes to processes for achieving this, the U.S. can some take lessons from Europe, where utilities are more likely to monitor temperature. Advanced flow metering technology that incorporates temperature monitoring provides a significant tool for utilities without the need for additional instruments.
In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.
Water utilities must protect the public health by producing a final product that meets all regulatory requirements. In addition, the water must be pleasing to the customer, with no taste or odor issues. And finally, utilities must stay abreast of emerging contaminants, health advisories, and new regulations. It’s a constant challenge to shoulder these responsibilities while staying within tight budgets. Utilities need a technology that helps them achieve multiple goals cost-effectively.
When drinking water leaves a treatment plant through giant pipes, with the help of huge pumps, the pressure can exceed 200 psi. The high pressure is a necessity because water must travel a long distance in some cases. Water towers scattered throughout the distribution system aid in the process so it can reach all utility customers. The problem is that not all distribution points in a water system are created equal.
Economist Harold Pollack's New York Times article suggesting priorities for your philanthropic work was a fun read for those of us who would love to imagine what we would do with $131 billion. Unlike Pollack, I'm not going to tell you how to give away your money — you earned it, it's yours, and you can do what you want with it.
Large-scale water-reuse treatment plants have had sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in those same locations.
The purpose of source water monitoring is to enable drinking water treatment facilities to identify changes in water quality, implement treatment strategies based on the characteristics of the water, optimize the treatment processes, and take preventative actions to protect the source water from intentional and accidental contamination.
Microbiological contamination is at the top of the CDMO threat list. A CDMO needs to have clearly defined procedures and allow client access to data.
Due to the dynamics of liquids and gases flowing through elbows, valves, pumps, and other pipeline structures, every flow-meter methodology has its own design limitations. Unlike Venturi meters, pitot tubes, orifice plates, and other devices, V-Cone meters provide highly accurate and reliable readings with minimal straight-pipe length restrictions and virtually no maintenance, in pipe sizes up to 120”.
As our ability to measure contaminants at ever smaller concentrations improves, “emerging contaminants” are on the rise. Per the U.S. Environmental Protection Agency (EPA), emerging contaminants are chemicals or materials characterized by a perceived, potential, or real threat to human health or the environment.
Electromagnetic meters (mag meters) are well established in terms of highly accurate performance for a variety of municipal and industrial water applications. Differences in their construction formats, however, dictate how easy they can be to install, maintain, and calibrate. Compare these three options to see the value of full-profile-insertion (FPI) mag meters and their associated advantages in real-world use.
An increase in extreme weather events combined with stricter regulatory requirements is making it more difficult than ever for municipalities to keep pace at their wastewater operations. As a result, asset management has been thrust into the spotlight.
Proficiency Testing (PT) is the name used by the International Standards Organization for a procedure also known as “inter-laboratory study” or “external quality assessment” or “ring test”. Proficiency testing, in simple terms, comprises a sample sent to a group of laboratories for measurement. The labs know what might be in the sample, but they don’t know exactly what is there or the concentration. Their results are compared with the known or true value and the lab is assigned a “Z” score to show how closely their result came to the target.
The business of water and wastewater is critical, but expertise in this area is finite — thus the trend towards outsourcing water operations, particularly in the industrial market. Whether it's securing and optimizing water use, running treatment equipment, sustainably releasing or reusing the water, capturing energy from it, or all of the above, it's often a wise business move to turn to experts. In this Water Talk interview, Miles Sherman, Regional Vice President of Services with Suez Water Technologies and Solutions, discusses the capabilities and benefits offered through this type of outsourcing, the various service models that exist, and the drivers that will continue to broaden the trend.
Using on-site sodium hypochlorite generation technology to make oxidant for water and wastewater treatment is cost-effective, safe, and environmentally responsible. But, as with any piece of equipment, choosing the right one and caring for it properly impacts both life cycle costs and effectiveness.
