U.S. to finance NOTL bulrushes

Edgar Lemon

A Niagara-on-the-Lake scientist is capturing interest in the United States with his pioneering efforts to purify municipal sewage with bullrushes.
The U.S. Environmental Protection Agency is interested in contributing financially to Edgar Lemon's three year-old "wetlands project," EPA official Donald Brown said in an interview yesterday.
In return for the money, which could total up to $120,000 (USD), the agency wants Lemon and his assistants to continue the project for two more years so it can monitor the results. Brown, an environmental engineer at EPA's research centre in Cincinnati, Ohio, said Lemon's work could determine if wetlands can be used for treating sewage in colder climates.
Several communities are successfully using wetlands to purify sewage in the southern U.S., said Brown, "but we don't have data on cold-climate wetlands".
Brown is coming to Niagara-on-the-Lake next month to observe the project in action.
Lemon and the Friends of Fort George, a local preservation group assisting in the endeavor, are hoping their efforts will help revolutionize the way municipal sewage is treated.
The project is being conducted next to the sewage treatment plant for Niagara-on-the-Lake's old town. It uses the root bed of bulrushes to filter contaminants from sewage effluent.
Tests conducted in an Ontario government laboratory show the bulrushes are purifying the sewage enough to meet all the province's guidelines for protecting the environment.
Lemon, a retired Cornell University researcher who settled in Niagara-on-the-Lake in the mid-1980s, says he's convinced wetlands offer a less costly, more environmentally friendly way of treating sewage.
The project is already receiving financial support from the province's Ministry of Environment.
The ministry provides an annual $15,000 grant and also spends about $1,000 a week to analyze the sewage effluent in a laboratory.
John Kernahan, Niagara Region's director of public works, said recently he's also impressed enough with the project to try it on a full scale.
The Region is meeting with the province to discuss the possibility of using the bulrushes in a smaller community like Campden in Lincoln, where sewage frequently leaks into groundwater from septic tanks.
Brown said yesterday the EPA is counting on the province and Region to continue their support while his agency is involved in the project.
The agency has already applied to Washington for the grant money, said Brown, and is now awaiting final approval.
Some extra red tape is involved, he added, since the project is taking place in another country.
