Couple things:

1. According to the CR article the problem is not as much arsenic that naturally occurs in the soil as it is human arsenic pollution which accumulates in soil and water:

Though arsenic can enter soil or water due to weathering of arsenic-containing minerals in the earth, humans are more to blame than Mother Nature for arsenic contamination in the U.S. today, according to the federal Agency for Toxic Substances and Disease Registry. The U.S. is the world’s leading user of arsenic, and since 1910 about 1.6 million tons have been used for agricultural and industrial purposes, about half of it only since the mid-1960s. Residues from the decades of use of lead-arsenate insecticides linger in agricultural soil today, even though their use was banned in the 1980
Being in the soil doesn't mean it's natural, and being organic doesn't mean it's free of pollution.

2. The Consumer Reports article also says this:

Though brown rice has nutritional advantages over white rice, it is not surprising that it might have higher levels of arsenic, which concentrates in the outer layers of a grain. The process of polishing rice to produce white rice removes those surface layers, slightly reducing the total arsenic and inorganic arsenic in the grain.

In brown rice, only the hull is removed. Arsenic concentrations found in the bran that is removed during the milling process to produce white rice can be 10 to 20 times higher than levels found in bulk rice grain.
There's no citation for that fact but it certainly sounds like arsenic levels will be higher in brown rice, and the chart included with the CR article seems to bear that out.
