Laboratory

The Laboratory has two equally important responsibilities.  First, the Laboratory must prove to State and Federal agencies that the clean water discharged into the Little Conewago Creek and the biosolids that become agricultural soil amendments meet or exceed all regulatory levels.  The testing includes intensive quality control and internal monitoring.  We must be able to prove that the “numbers” are honest and trustworthy.  The second responsibility of the Laboratory is to monitor the treatment process and give information to the operators.  This enables them to effectively and efficiently control the process.

The Laboratory is accredited by the State and must conform to Chapter 252 regulations.  Chapter 252 (Environmental Laboratory Accreditation) was established in 2006 “to protect the public health, safety, welfare and the environment by ensuring the accuracy, precision, and reliability of data generated by environmental laboratories” (Section 252.2).  The Laboratory is also involved with troubleshooting the processes, researching and /or improving methodologies, and assist in the data management system.

Here is a list of some analyses performed:
