KSingh Awarded Janesville Landfill Project

K. Singh & Associates, Inc. (KSA) was retained by the City of Janesville to provide environmental sampling, analysis, management, and reporting for four landfills throughout the city. Each site requires monitoring for groundwater quality while two also call for surface scan monitoring to determine if methane is being contained. The liquid monitoring scope includes groundwater, leachate, lysimeter, gradient control, gas condensate, and surface water.

Details of the sites consist of:

Closed Demolition Landfill/Compost Site | The 10-acre landfill operated for 11-years in the 1980’s and early 1990’s and accepted brush, wood wasted, and miscellaneous construction materials. The landfill has five monitoring wells and one non-potable private well that are sampled.

Clean Fill Site | This 10-acre landfill opened in 1992 and accepts brush, wood wastes, and construction materials. This site also has five monitoring wells that are sampled on an annual basis, of which two are shared with the Closed Demolition Landfill/Compost Site.

Rock County / City of Janesville Sanitary Landfill | This site includes a 45-acre solid waste landfill that operated for about 11-years, closing in 2006. Thirteen monitoring wells are sampled on a semi-annual basis with additional parameters collected annually. Other sampling includes one grab sample from a lift station, quarterly measurements of leachate pumped from the lysimeters, and gas condensate sampling from a drip leg. The project also involves quarterly surface scan monitoring.

New Expansion Sanitary Landfill | This landfill began in 2005 and consists of 38-acres that have been broken into five phases. Three phases are currently constructed and contain a leachate collection system. Landfill gas is also collected in two of the phases. Twelve monitoring wells are sampled on a semi-annual basis with additional parameters collected annually. Leachate samples are collected from three on-site and one off-site manholes on a semi-annual basis. Surface water runoff monitoring is also required from the sedimentation basis. The project also involves quarterly surface scan monitoring.
