PW Landfill and Piedmont Environmental Council Win Environmental Awards



The 2013 Virginia Governor’s Environmental Excellence Awards were announced on April 10, 2013, at the Environment Virginia Symposium in Lexington, VA. Among the nine Gold Medal Winners were two wonderful local organizations: Prince William County’s Solid Waste Division for its Sustainability Program and the Piedmont Environmental Council for its Land Conservation Program.

Prince William County’s Sustainability Program at the landfill encompasses recycling, groundwater protection, storm water management, erosion control, air quality monitory, alternative energy generation, material reuse and habitat development. As a part of its community outreach efforts, the landfill facilities have been opened to citizens, school groups, bird watchers, business groups and professional organizations. The Solid Waste Division shares credit for the program’s success with county management support, a strong working relationship with regulatory agencies, and community involvement and pride. Tom Smith, chief of the County’s Solid Waste Division, said, “Prince William County recognizes the importance of protecting the health, safety, and environment of the community we serve. I’m very proud of what the County has accomplished with regards to environmental sustainability.”

In 2012 the landfill was designated an “Audubon at Home” wildlife sanctuary. According to the Prince William Conservation Alliance, who organizes the annual Nokesville Christmas Bird Count, the Prince William County Landfill has the largest numbers of Bald Eagles in the county. On Christmas day 2012 the Birders counted 10 adults and 10 immature Bald Eagles, along with many gulls including 650 Ring-billed Gulls and three Great Black-backed Gulls.

The life expectancy of the landfill has been prolonged to 2065 through expanding recycling and composting in the county. The landfill is targeting to achieve 40% recycling countywide by 2015. The landfill is built as a series of cells that include liners of plastic membranes and watertight geo-synthetic clay liner fabric on the bottom along with a leachate collection system. At the end of each day, earth covers the trash deposited in the cell, to keep animals away and improve aesthetics. When a cell if full, it is capped to prevent (or at least limit) the rain that percolates through the landfill and covered in soil.

The PW Landfill has 48 groundwater monitoring wells, and 78 landfill gas extraction wells. Landfill gas is generated during the natural process of bacterial decomposition of organic material contained in the trash buried in the landfill. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide with varying amounts of nitrogen, oxygen, water vapor, sulfur, and other contaminants. The gases produced within the landfill are either collected and flared off or used to produce heat and electricity. The landfill gas cannot be allowed to build up in the landfill because of the risk of explosion. More than 7 million tons of trash buried at the landfill. That trash currently generates 2,700 standard cubic feet per minute of landfill gas and will increase. Flaring the gas releases greenhouse gases to no purpose.

In 1998 the County formed a partnership with Fortistar to install a landfill gas collection system and a 1.9 MW energy recover facility which is a two engine turbine that burns the gas to make electricity that is sold to NOVEC, the local electric cooperative. The 1.9 MW energy recovery system is currently operational, but the amount of landfill gas generated has increased from 1600 scfm in 1999, to the current amount of 2600 scfm, and is utilizing less than 25% of the currently available landfill gas for energy recovery. Three (3) additional turbine engines are scheduled to be installed by August 2013 to produce additional 4.8 MW of electricity. Additional gas will be available even after the new engines are installed and will provide landfill gas to heat the Fleet Maintenance Building and provide fuel to the Animal Shelter through a new gas pipeline. The landfill is moving forward to develop plans to create an “ECO Park” at the landfill.

The Piedmont Environmental Council (PEC) located in Warrenton received their award for their land conservation work combining public and private initiatives with market-based solutions to achieve regional conservation goals. Heather Richards, accepted the award on behalf of the Piedmont Environmental Council and said, “We are honored to be recognized for over 40 years of work in preserving the scenic, cultural, and natural resources of the Piedmont. The need for land conservation remains strong throughout our region and all of Virginia, and we look forward to continuing our partnership with landowners and the community to protect the landscape that makes this place special to us all.”

PEC staff work with landowners bringing a holistic approach to land conservation. They see the decisions of individual landowners to protect their land in a larger, collective context. PEC reaches out to landowners to raise the idea of land conservation and meeting with those who are interested in conserving their land bringing experience and knowledge to help the landowners through the process. As an accredited land trust, they also hold conservation easements directly. PEC currently holds 47 easements -- protecting over 6,600 acres in our region.

I know PEC through their Sustainable Habitat Program. PEC works with landowners throughout the region on land management strategies to improve wildlife habitat and water quality. PEC works to educate all types of landowners about our region’s crucial ecosystems and the small and large steps we can all take to protect our wildlife corridors and watershed. PEC staff stays up to date with local, state and federal policy regarding land conservation. This year, PEC played a major role in writing and introducing a bill in the Virginia General Assembly, HB 1398, which protects and expands the tools available for helping landowners conserve their land in perpetuity. The bill passed with board bi-partisan support.

Virginia Extension -Help and Information for Private Well Owners


I spoke with Erin James Ling who is the coordinator of both the Virginia Household Water Quality Program, VAHWQP, and the Virginia Master Well Owners Network, VAMWON, as part of her job in the Biological Systems Engineering department at Virginia Tech. Erin works under Dr. Brian Benham, who re-launched the Virginia Household Water Quality Program in 2007 with a National Institute for Food and Agriculture, NIFA, grant. The VAHWQP uses the grant to sponsor and subsidize drinking water clinics held throughout the state where homeowners can get their well water analyzed for 14 chemical and bacteriological contaminants and cost only $49 (there are locations where the cost of the analysis is fully underwritten by the county extension office). The program consists of two meetings- one to get instructions and test kits, and the other a month later to get results and provide interpretation and recommendations. Samples are dropped off at the Virginia Cooperative Extension Office sponsoring the program and driven to Virginia Tech for analysis. The NIFA grant and trained extension volunteers have allowed Virginia to hold and subsidize the cost of the analysis for the water clinics in a dozen or more counties each year. 

Erin joined the program in 2008 as the coordinator of the programs (which is about half her job) and with additional funding for 2013 will be able to devote more of her time to developing and expanding the programs. The focus has been primarily on training extension agents and running the water clinics, but Erin want to move the program beyond that in the future. Since its inception in 1989 drinking water clinics have been conducted in 87 counties across the state analyzing 16,000 water samples. Since the re-launch of the program in 2008 3,000 household samples have been analyzed and results confidentially returned to participants. The program retains the analytical data on a county by county basis, but all identifying information like address or well owner are not kept with the data. The county water analysis data and questionnaire information is only accumulated to develop a statistical database on groundwater and household water quality by county and may someday be one of the more detailed private water supply quality databases in the nation- a database that can be mined for patterns in water quality, geology and well systems. In addition, the demographic information could help to develop better messaging to reach more well owners more effectively.

The Virginia Cooperative Extension was set up to meet the needs of rural landowners and brings the university knowledge and reliable information resources to rural people through the extension agents. As the rural population has changed, the services offered by the extension programs have evolved beyond the farm agents (like Kimbel, Hank Kimbel of Green Acres) to master gardeners, and protection of groundwater and health of Virginia private well owners. Erin with a master’s degree in Environmental Pollution Control and a second master’s degree in Rural Sociology is uniquely qualified to develop programs to build awareness of the risks and responsibilities of private water well ownership and develop programs to communicate technical information to the public.  The Household Water Quality Program and VAMWON program provide information, education, and tools that you can use to improve the quality of your life, help you determine if you need a water treatment system and if needed what system is right for you. The VAMWON consists of Extension agentsand screened volunteers trained in the proper design, management, andmaintenance of private water supply systems (springs, wells, and cisterns).VAMWON trained extension agents organize and conduct the county-based drinking water clinics and serve as a local resource for clientele with household water quality concerns. The schedule of water clinics for 2013 is available at this link.

The programs Erin coordinates are linking rural health with water quality information. She plans to expand the VAMWON program to increase capacity and reach and include septic systems. Maintaining septic systems and Alternative on-site sewage systems is really important to health. Household wastewater is loaded with disease-causing bacteria and viruses, as well as high levels of nitrogen and phosphorus. If a septic system is well-maintained and working properly, it will remove most of these pollutants. Insufficiently treated sewage from septic systems can cause groundwater contamination that can result in contamination of private water wells which can spread disease and impact household health. Understanding and maintaining your septic system and well and regularly testing your well water quality are the best way to protect the quality of your drinking water and the health of your family.
