The San Antonio Chapter has Expanded its Public Education

The ABPA-SA Chapter has been trying for many years to develop a public education program that would be understood by most of the citizens in our community. The members became aware of the difficulty of being able to relay information about the hazards of cross connections and the need for backflow preventers on the irrigation systems owned by many of the households in today’s municipalities. One of the members at a monthly meeting said, “If you folks come up with an idea, I can build it”. The discussion immediately started with a list of the many hazards present in a residential irrigation system. The list included hazards such as insecticides, herbicides, fertilizers, and pet and rodent excretions. The stage was now set to try and create a model that would relay this basic information to the public in a simple and easy to understand manner that was almost instantaneous, since most people will not spend more than a few seconds looking at a model.

Sewer Workers May Face Ebola Threat

Researchers say sewer workers operating near a hospital treating Ebola patients may be at risk of picking up the virus, which can cause a fast-acting and often fatal disease.

A study published in this month’s edition of Water Environment Research, the journal of the Water Environment Federation, examined guidance from the World Health Organization and the Centers for Disease Control and Prevention on how to dispose of waste from Ebola patients.

There is no research on whether the guidance from these groups ensures safety for wastewater workers, particularly if they inhale fumes in the sewer system, the study says.

“Current World Health Organization and Centers for Disease Control and Prevention guidance for the disposal of liquid waste from patients undergoing treatment for Ebola virus disease at hospitals in the U.S. is to manage patient excreta as ordinary wastewater without pretreatment,” the study said.

What Causes Contamination Through Cross-Connections to Occur?

Under intended flow conditions, distribution systems are pressurized to deliver finished water from the treatment plant to the customer. However, two situations can cause the direction of flow to reverse: pressure in the distribution system can drop due to various conditions or an external system connected to the distribution system may operate at a higher pressure than the distribution system. These differences in pressure can cause contaminants to be drawn or forced into the distribution system. Contamination introduced due to backflow into the distribution system may then flow freely into other customer connections. The following conditions must be present for contamination to occur through cross-connections.

Twelve States Earn Failing Grades for Lead In School Drinking Water

A new report shines a light on lead-contamination of drinking water in schools, highlighting how poor policymaking at the state and federal level poses a threat to children in various states.

The report released last month by the Environment America Research & Policy Center reviewed policies in 15 states for how well they protect children from lead contamination of drinking water at schools.

California, Connecticut, Georgia, Florida, Maryland, Maine, Pennsylvania, Ohio, Oregon, Texas, Washington, and Wisconsin all earned "F" grades.

Illinois and Massachusetts earned “D” grades.

Spinning Biogas Into Gold With Combined Heat And Power

Glen Illyn, IL, is a fairly typical American suburb, with 27,000 residents living about 40 minutes from the bright lights of Chicago.

The local wastewater treatment plant, the Glenbard Wastewater Authority’s Advanced Wastewater Treatment Facility, is typical as well. It has a normal daily design flow of 16 MGD and peak design flow of 47 MGD. Its advanced treatment includes primary screenings; grit removal; primary clarification; high-purity, oxygen-activated sludge; clarification; tertiary treatment; and UV disinfection.

But in one key way, Glenbard is different than many other wastewater treatment plants around the country. It had grown interested in resource recovery and utilizing the influent it treated to help power and fund its operations and that interest has blossomed into an estimated $200,000 saving in annual energy costs.
