A new study released on June 17, 2015 by the Northeast-Midwest Institute and the U.S. Geological Survey found that current water quality monitoring in the Lake Erie drainage basin is inadequate for evaluating agricultural management practices for improving the health of Lake Erie.
For example, in Indiana the age of consent for sex is 16, but there is a close in age exception that makes it legal for a person younger than 18 but above 16 to still be able to have sex with a 14 year old without being guilty of a crime.
The federal law establishes the age of 12 as the minimum age of consent, while the age at which there are no restrictions for consensual sexual activities is 18 (sex with someone 12-18 is not illegal per se, but can still be open to prosecution under certain circumstances).
