WOODBURY - The last week of the New York state legislative session is underway in Albany.

Still unresolved is a proposal to legalize marijuana for medical purposes and a series of bills targeting the heroin epidemic. A proposal to protect Long Island's drinking water got a lot of attention Monday.

After a four-hour bus ride to the state Capitol, a group of Long Island environmental activists urged state legislators to pass a bill they say is crucial for protecting the drinking water and waterways around the Island. The bill would require the state Department of Environmental Conservation to regulate and monitor how much fertilizer and pesticides can be used.

Among the the opponents of the bill are Long Island farmers, who are afraid the state will impose what they consider unfair limits on fertilizers that they say will hurt their industry. While it is expected to pass in the state Assembly, the bill faces a tougher battle in the Senate.

Senate co-leader Dean Skelos (R-Rockville Centre) was non-committal about its chances of passage.

As for the biggest issue on the agenda, medical marijuana, legislative leaders and Gov. Andrew Cuomo are continuing to try and work out differences in their proposals.
