From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of July 25, 2011.
This week we feature another series of mystery sounds. Have a listen for about 30 seconds, and see if you can guess where these sounds were recorded. And here’s a hint: It’s certainly no WASTE of time to learn about this community water facility.
If you guessed a wastewater-treatment plant, you’re right! Conventional wastewater treatment removes solid materials, disinfects water, and removes materials that can reduce oxygen in streams receiving a plant’s discharge. As noted in the recording, some plants now are taking extra steps to reduce levels of nitrogen and phosphorus, in order to help prevent an excess of those algae-stimulating nutrients in aquatic systems. A major part of Chesapeake Bay restoration efforts, for example, is increased nutrient-removal by wastewater-treatment plants. One part of such efforts in Virginia is the Water Quality Improvement Fund, which provides money for nutrient-removal projects. By law, the fund receives 10 percent of annual general revenues in excess of appropriations, so the estimated $311-million surplus for Fiscal Year 2011 that Governor McDonnell’s office announced on July 19 will mean an estimated $32.2 million for the water-quality fun

From the Virginia Water Resources Research Center in Blacksburg, I’m Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.
Acknowledgments: Quinn Hull recorded this week's sounds, and Bobby Epperly of the Blacksburg-VPI Sanitation Authority gave the plant tour during which the sounds and his comments were recorded.
Sounds heard in the recording: Incinerator room; chlorination chamber; high-pitched screech from a pump room; grit removers; algae-scrubbers on secondary clarifiers.
