| Microbiology Lab
This is where we test for coliform bacteria. We use the membrane filtration method.
The bacteria is collected by filtering a sample of your water through a filter
with tiny pores. The filter is then placed in a petri dish that gives coliform
bacteria the nutrients they need to grow. If the bacteria is present a colony
will form on the filter within 24 hours. Inorganics
Lab This is where we test for a large number of common contaminants
such as nitrate, nitrite and lead. We employ a variety of techniques such as ion
chromatography, atomic absorption spectroscopy and wet chemistry.
Ion Chromatography This is where we test for
ions such as nitrate and nitrite. A sample is injected into the instrument where
the ions are separated and measured individually. Wet
Chemistry This is where we use "classical methods" to test
for things like pH and hardness. We employ a variety of techniques including spectroscopy,
Ion selective electrodes and extractions. Atomic absorption
This is where we test for metals such as lead and copper. We use two types of
atomic absorption spectroscopy, flame and graphite furnace, depending on what
metals we are testing for. Organics
lab This is where we test for organic chemicals that exist in drinking
water. These chemicals include the Volatile Organic Compounds, pesticides and
herbicides. We use several Gas Chromatography systems and several High Performance
Liquid Chromatography methods to test for these chemicals. |
