Impact assessment of the Lawrence waste water treatment plant on the Wakarusa River: follow-up assessment.
This two-year study continues the chemical and biological monitoring of the Wakarusa River that we performed in 2013-2015 prior to the City of Lawrence’s new wastewater treatment plant (WWTP) coming into operation in 2018. That 2013-2015 baseline study fulfilled a pre-discharge monitoring requirement for the discharge permit that the City obtained from the Kansas Department of Environment and Health. The two study sites are located upstream and downstream of the WWTP discharge. To determine if discharge is affecting the Wakarusa River, we repeat the study at the same sites, using the same methods, to compare the downstream site to the upstream site which serves as a control site since the previous study showed no biological or chemical differences between the two sites.
