Research on Road Salt

One major challenge we faced when starting the KARS project was collecting and sharing web resources for our research. The solution we found was Diigoan impressive and very useful site which compiles links to be shared and stored for an individual or among a group.

Diigo is a Great tool for collecting, storing and sharing links on the web.

Diigo is useful in many ways  such as holding onto important info/ websites that you know you will need again. It also can be used in other ways, from storing personal stuff to working to sharing work with your coworkers, and Diigo has been helping us out a lot. We as a class couldn’t find the links that we found the day before, so now when ever we need that link again we put it in our Diigo account. We now know that we can store our links in Diigo.

Here are some current articles that we came across online and stored in Diigo.

1)  Rivers in wintry cities remain salty year-round | Great Lakes Echo

The article is basically about how the salt continues to affect road side streams  and rivers. the salt can also spread into the groundwater areas and the aquifer. The road salt stays there for years and years maybe decades, until it’s properly removed or diluted. Road side streams also hold plenty of wild animals that live there that could get contaminated and can have birth defects such as bent tails.

2) Road Salt’s Damaging Effects Prompt Tech Alternatives : Discovery News

This article describes the technology of how salt is spread on the roads and how it hurts the environment. 22 billion tons of road salt is used nationwide each year and it doesn’t disappear. Minneapolis-St. Paul about 260 pounds of road salt is used per person each winter season. which means every year about 852.8 million pounds of road salt are used each year for the area of Minneapolis-St. Paul. In that state, they are now using salt trucks equipped with computers that can sense weather conditions, road surface temperatures and more, thus calculating the optimum amount of salt that is needed on the roads. Such technology can save both money on salt, as well as limit the effects that salt has on local water systems.

3) What Happens to All the Salt We Dump On the Roads? | Surprising Science

Recent studies have shown that road salt remains in groundwater for decades and affects everyone who draws drinking water from that local area, including humans and wildlife. Salt on the roads also attracts wildlife to the roads because they like to lick the salt. For  many reasons, environmental agencies are encouraging governments to try new alternatives to salt for de-icing.  Over the past few years, beet juice, sugarcane molasses and cheese brine, among other substances, have been mixed in with salt to lower the total chloride load on the environment.
