The inorganic chemistry lab performs a wide variety
of analysis used in water quality and wastewater monitoring. Tests
are performed using both automated and non automated analytical
methods. Analyses performed in this lab are used for diagnostic
water quality studies, verification of wastewater treatment plant
permit requirements, landfill assessments and air pollution studies.
Chlorophyll, alkalinity and total suspended solids are examples
of non automated tests, which are used in long term water quality
studies. Biological oxygen demand and total suspended solids are
key parameters used in the Department oversite of wastewater treatment
This lab uses automated colorimetric and ion chromatographic techniques
to support many of the Department's long term monitoring studies.
Since Vermont's economy has a large agricultural component, monitoring
our waterways for nitrates, nitrites and phosphorus is critical.
These three nutrients are huge components of agricultural runoff
and can spell disaster for aquatic ecosystems if they are present
in high concentrations.
