The Laboratory Section of Environmental Services provides the City with expertise as well as cost effective and reliable chemical and microbiological analytical services. Each laboratory is equipped with state-of-the-art analytical equipment that provides accurate results based on EPA approved methods. The mission of the Central Laboratory is to ensure the accuracy and integrity of data generated from analyses conducted on the water systems and processed discharges to the environment. Our division utilizes the most cutting edge technologies, practices, and equipment to obtain the most accurate results regarding water quality. 


The laboratory instrumentation includes:

Fourier Transform Infrared Spectrometery

Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) is used to detect trace metals in various water, and wastewater samples.

Gas Chromatography And Mass Spectroscopy

Gas Chromatography and Mass Spectroscopy (GC/MS) are utilized to detect and quantitate specific organic contaminants.

Ion -exchange -chromatography

Ion Chromatography allows our scientists to analyze multiple ion parameters on a single sample simultaneously.

General Tests include: pH, conductivity, dissolved oxygen, biological oxygen demand (BOD), chemical oxygen demand (COD), turbidity, solids, ammonia, nitrate, nitrite, cyanide, total and dissolved reactive phosphorus, oil and grease, total petroleum hydrocarbons, detergent, and hardness.

All laboratory personnel are highly trained with extensive experience in chemistry, microbiology and environmental science. Water quality analyses are performed by qualified chemists, reviewed by laboratory supervisors, and validated by a quality assurance officer to ensure the quality and consistency of our methods. In addition to our team of chemists we also have an emergency response team and water section personnel trained in proper field sampling who are responsible for the collection of water.
