Boxerwood began as a private garden, with no awareness that it would one day become a public facility. Our Visitors Center septic system, installed in the 1950s for a family of five, became obsolete and inadequate and in fact might have been be leaking its waste into the groundwater. To meet the long-term demand of our growing public, Boxerwood needed far more substantial wastewater-handling capabilities.  

The solution for Boxerwood’s waste treatment system problem is NEWTS – an innovative, educational mini-ecosystem that cleans and efficiently recycles the Visitor Center’s water and waste. One-of-a-kind in our area, the Boxerwood System, is a man-made compacted wetland that is visually attractive and environmentally sound.  

Unlike chemically based systems, this System’s waste treatment takes place through a series of managed environments. From the restrooms and kitchen, the waste first travels to septic tanks, through a recirculating media-filter where helpful bacteria continue  to break down and ingest organic pollutants. Next, in the greenhouse, it goes through our Constructed Wetlands -- lined trenches where common wetland microbes, plants and animals will filter and clean the water. The water then goes through ultra-violet rays provided by the sun or a lamp when not enough natural UV rays are available. Finally, the water is given to plants that transpire the liquid through their leaves. All of this takes place in a remarkably small space.  

Added Benefits:   

bulletThe Boxerwood Nature-Emulating Wastewater Treatment System is a teaching tool demonstrating complex and delicate ecosystems and our own interdependence with plants, wildlife and watersheds. Through educational programs, the Boxerwood System is a key element toward fulfilling Boxerwood’s mission of "educating and inspiring people of all ages toward becoming successful and environmentally responsible stewards of the Earth." 
bulletIn addition to solving our problems, systems like ours could also be a major solution to the threat to water quality posed by nitrate pollution in our local and the greater Chesapeake Bay watershed.  

Nitrate pollution is the Bay’s most significant problem -- causing algal blooms, which deprive the aquatic environment of needed sunlight and dissolved oxygen, resulting in compromised aquatic plant and animal life.

Septic systems are one of the top 10 sources of groundwater contamination in 35 out of 37 states surveyed by the EPA.  They also are the second largest source of groundwater nitrate contamination in the U.S. They are the third major contaminant of groundwater in the U.S., rating higher than industrial facilities and urban runoff.

Clearly, alternatives to traditional septic systems are critical to the future of the health of the Bay, our groundwater and us. 

By responsibly addressing the leaking nitrate issue at Boxerwood, we are directly addressing a significant environmental problem and will carry awareness of this problem and a sustainable solution to our constituents.
