A primary reason to drink healthy organic coffee instead of regular coffee is to avoid unwanted contaminants such as pesticide or herbicide residues or chemicals from synthetic fertilizers.

Just what is in non organic coffee?
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
One of the most complete analyses of contaminants in coffee comes from the Australia New Zealand Food Standards authority.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
. Their study, Survey of Chemical Contaminants and Residues in Espresso, Instant and Ground Coffee is informative albeit somewhat lengthy. Here are some of the high points and our comments.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
This survey considered a range of chemical contaminants thought to be present in coffee. The range of chemicals analysed in this survey included metals, acrylamide, furan, polycyclic aromatic hydrocarbons (PAHs), ochratoxin A , and a range of pesticide residues.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
Using state of the art technology scientists tested 164 samples of espresso, ground coffee and instant coffee purchased from stores in Melbourne and Sydney, Australia. The authors also compare their results to testing done in other nations.

It is important to note that some of the things they tested for are produced in processing of coffee and are therefore found in both non organic and organic coffee.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
Toxins from fungi are caused by improper storage of coffee beans and are also found in both non organic and organic coffee.

And if the water you are using contains things like arsenic, don’t blame it on the coffee.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
That having been said here are some of the results of what is in non organic coffee. These are chemicals found on non organic coffee.

Although pesticide residues, beryllium, mercury and ochratoxin A (fungal toxin) were not found these have been discovered in other testing of non-organic coffee including in previous testing in New Zealand.

Roast Your Coffee to Be Safe
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
Even if you are drinking regular coffee that originally has pesticide contamination you are better off with roasted coffee than green coffee.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
It turns out that roasting degrades pesticides. NCBI reports a study from Japan about pesticides in coffee beans during the roasting process
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
In Japan, maximum residue limits for pesticides (MRL) in coffee are set on green coffee beans, but not roasted coffee beans, although roasted beans are actually used to prepare coffee for drinking.

Little is known about the behavior of pesticides during the roasting process. In the present study, we examined the changes in the concentration of pesticide (organochlorine: γ-BHC, chlordane and heptachlor) residues in coffee beans during the roasting process.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
We prepared green coffee beans spiked with these pesticides (0.2 and 1.0 μg/g), and the residue levels in the beans were measured before and after the roasting process.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
We determined the residual rate after the roasting process. γ-BHC was not detectable at all, and more than 90% of chlordane was lost after the roasting (3.1 and 5.1% of chlordane remained in the beans spiked with 0.2 and 1.0 μg/g of chlordane, respectively).
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
A low level of heptachlor (0.72%) was left in the coffee beans spiked with 1 μg/g of heptachlor. Disappearance of γ-BHC during the roasting process may be due to the high vapor pressure of γ-BHC, while chlordane has a lower vapor pressure.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
We also examined the behavior of piperonyl butoxide and atrazine during the roasting process. Piperonyl butoxide behaved similarly to chlordane, but atrazine disappeared after the roasting process, because it is unstable to heat.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
Your best bet if you want to avoid consuming pesticides with your coffee is to drink only organic coffee.
http://buyorganiccoffee.org/1878/what-is-in-non-organic-coffee/
However, it is reassuring that roasting tends to degrade these chemicals.
