Today, there is legislation to eliminate combined sewer overflows. Heavy fines are levied by the EPA against communities that violate this law. The EPA has been reasonable with enforcement because the costs are great--not to mention that it will take time to expand the infrastructure. However, as municipalities and utilities have learned, eliminating overflow events is a must.

Fluid Samplers: Vacuum vs. Peristaltic   Water & Wastes Digest September 2003   Tim Gregorski
A fluid sampler is essentially a smart pump that takes a liquid sample from a source and deposits it into one or several containers for inspection. Fluid can either be pulled up the intake hose, or pushed from the source. Two types of samplers are typically used, vacuum/compressor and peristaltic. When choosing a sampler, correct analysis of your application is vital.

In 1957 The Dow Chemical Corp. addressed the negatives of using bromine by creating a brominated ion exchange resin, which opened up the use of bromine in offshore water treatment applications.2 Today, polybromide resin is used in many offshore water treatment systems. The fact that bromine can be added to water that previously has been chlorinated makes polybromide resin a practical solution to accommodate the multiple sources of water in offshore applications.

Montgomery County Works With EPA To Upgrade Infrastructure   Water & Wastes Digest May 2003
More and more communities face the dual problem of aging infrastructure and overdevelopment due to population growth. Under the Federal Clean Water Act (CWA), EPA is keeping a vigilant eye on the problem. When a community does not meet CWA regulations for sewage overflow, EPA works with that community through long-term loans and expertise to develop a solution. Such is the case in Montgomery County, Ohio.

Chemical Tank Cleaning Eliminates Town's Chlorine Demand   Water & Wastes Digest May 2003   Ulrich Reimann-Philipp, Ph.D.
Finished water quality often declines in storage facilities.

Chlorine Residual Boosting in Distribution Water: Problems with Chlorine Application and Disinfection Byproducts - Part 1   Water Engineering & Management April 2003   Shin-ichi Tokuno
Previous research on the boosting of chlorine residual1 included how to increase low levels of chlorine disinfectants (free and combined chlorine) in the distribution system. Simple bench tests using a pocket photometer showed that there are no problems in boosting the low level of chlorine residual when boosting the same disinfectant to the water (e.g., free chlorine to free chlorine, or chloramine to chloramine). In the boosted chlorine residual, there is no significant instability in decay or dissipation during the time needed (72 hours) after boosting for the small utility distributors.

In the Field: Stormwater Treatment at a New Continental Airport Terminal   Water Engineering & Management March 2003
Airports potentially can generate enormous amounts of polluted stormwater runoff. In addition to hydrocarbons such as oil and fuel from cars, trucks and planes, winter weather brings added sand and salt to the roadways. Expanding the terminal area for Continental's new Global Gateway at Newark Liberty International Airport in late 2001 included increasing the paved areas around the terminal to accommodate the new taxiways and roadways. The system demonstrates the effectiveness of applying stormwater treatment technology to an already congested area where competition for space is fierce.

A big player for L.A. water   Roads & Bridges March 2003
The California Department of Transportation (Caltrans) builds and maintains some of the world's busiest highways, including the extensive Southern California freeway system. I-210 is one of these roads. In L.A.'s arid climate, rainfall events are infrequent but often intense, and the runoff is usually packed with all kinds of pollutants and trash. Caltrans engineers began looking at flow-based treatment devices, which accept a flow of water, put it through a treatment process, then release the water to continue its journey downstream.

Arsenic Treatment Options for the Southwest   Water Quality Products February 2003   Arizona Water Quality Association
While high concentrations of arsenic are found mostly in the Western region of the United States, parts of the Midwest and New England show levels of arsenic that exceed the newly approved U.S. Environmental Protection Agency (EPA) standard of 10 parts per billion (ppb). Individuals not willing to wait for their water system's compliance with the arsenic standard currently are looking for treatment systems to use in their homes. POU and even point-of-entry (POE) treatment systems are an attractive solution for these individuals. The process should begin with a basic understanding of arsenic contamination and the element's chemistry, a complete water quality analysis of the application-specific water and the knowledge of available technologies.

Integrated Technology Simplifies Dewatering Process at Two Municipal STPs   Water & Wastes Digest February 2003   Robert W. Mau, USFilter
The borough of West Mifflin, Penn., is a community located about nine miles southeast of downtown Pittsburgh. For years, the West Mifflin Sanitary Sewer Municipal Authority (WMSSMA) hauled liquid from its New England STP (a 1.2 mgd plant) to the Thompson Run facility (a 4.5 mgd plant), where it was processed on a belt press for dewatering. However, the hauling and associated labor proved very costly, and it was not always easy to coordinate dewatering schedules for both plants. Additionally in the late 1990s, the WMSSMA faced a requirement to achieve higher cake solids and provide odor control that would respect nearby homes and businesses. Moreover, space constraints and staffing reductions necessitated a simple-to-operate installation.

Impact of Mixing Chlorine and Chlorine Dioxide on Total Trihalomethane Formation - Part 1   Water Engineering & Management August 2002   Douglas Rittmann, Ph.D., P.E., and Anthony Tarquin, Ph.D., P.E.
Two rules in 1986 amendments to the Safe Drinking Water Act are challenging many water utilities to meet stricter water quality requirements. The Surface Water Treatment Rule (SWTR)2 and the Disinfection?Disinfection By-Products (D-DBP) Rule3, are requiring utilities to implement more advanced technologies in water treatment. The Surface Water Treatment Rule emphasizes the need for utilities to meet minimum levels of disinfection for surface waters, whereas the Disinfection/Disinfection By-Products Rule limits the disinfectant byproducts. Therefore, utilities will have to implement a treatment approach that balances the benefits of disinfection against disinfection byproducts.

Effects of Recharge of Chlorinated State Water Project Waters to Groundwaters in Lancaster Area of California   Water Engineering & Management April 2002   Hisam A. Baqai, P.E., G.E.
As the population in Southern California increases, more and more demands are being put on the state’s groundwater resources, further exacerbating the overdraft problem. Many communities in Southern California are recharging their aquifers with imported surface waters to combat this problem. The major recharge normally is carried out during wet weather periods when surface water is plentiful. However, recharging these groundwater aquifers with imported surface water can create the potential for water quality degradation. The problem can start when surface water is disinfected with chlorine to prevent biofouling and remove pathogens.

Practical Engineering Combined with Sound Operations Optimizes Phosphorus Removal   Water Engineering & Management April 2002   Daniel Bolduc and James Fitch, P.E.
Built in the early 1970s, The Oakland, Maine, Wastewater Treatment Facility (WWTF) treats and discharges approximately 300,000 gallons per day (gpd) of wastewater to the Messalonskee Stream. The facility was designed as a conventional activated sludge secondary treatment system to be used principally for BOD and TSS removals. The secondary effluent enters the Messalonskee Stream upstream of several impoundments. This practice has resulted in a steady decline in the water quality of the stream as evidenced by increased algae blooms and other signs of euthophication in impoundments located downstream of the discharge.
