Water Sampling

Today Martin and I took water samples from several streams on University property. While Martin took samples which were sent off to a lab to check for nitrates, ammonia, organic matter, and phosphates, I recorded dissolved oxygen and temperature. It was quite fun!

Water samples are taken on a monthly basis, especially because of possible contamination from both agriculture and laboratory-related practices. High levels of ammonia are of particular importance as it is harmful to the many fish and plants.

It began to rain so we didn't go to all the sites, but even in the rain the grounds look beautiful.

The tools: recording devices, water sampling bottles, dissolved oxygen meter.

The next day, Martin tested one of the water samples collected close to the physics building for glycol, which is anti freeze. Several years ago there was a leak and some glycol got into the water system. Glycol isn't regularly toxic, but in water it readily breaks down and depletes the oxygen supply.

This is the glycol testing kit. Even the slightest trace of glycol (far left, or nearly clear with just a tinge of purple) is cause for concern and action.
