Living lightly--Halley research station

.
In Madison, erosion from construction sites is responsible for 19% of the phosphorus in our lakes.  Construction is a major cause of Madison's poor air quality.

Nationwide, a recent study shows the industry causes $14.7 billion in economic damage a year.*  Those costs are paid by all of us.

So there's a need to find greener construction techniques--to build and live lightly on the land.


Halley VI Research Station in Antarctica is a striking example of what's possible.  The buildings were built from prefabricated modules, placed on legs above the ice.

On January 29, temperatures reached 54 F, with rainfall of 1.84 inches. Findorff Contruction wasn't prepared for the rain.
 
There was a sediment spill to Lake Mendota.

View from the lake. 

A gap in the silt fence along the lakeshore, plus construction dirt spilling over into the lake.

Photos were taken on a Saturday, when temperatures were about 38 degrees.  I wanted to see if there was enough meltwater to cause erosion of sediment into the lake. Water erosion wasn't evident.

But when snow was cleared, a lot of dirt got mixed with the snow, which was dumped outside the sediment fence.  So some dirt is getting into the lake.
