New Jersey is in the northeastern United States and provides its citizens with an abundant amount of water, forests and minerals for natural resources. Nearly half of the state is covered in forested regions, while every border of New Jersey, except the northern, is surrounded by water. These bodies of water include the Atlantic Ocean, the Hudson River and the Delaware River. New Jersey is also a major source of gravel, sand and clay minerals.
The Garden State is on the coastline of the Atlantic Ocean, which offers a boost in the state's economy due to the shipping trade and resort cities. The largest freshwater lake in New Jersey is Lake Hopatcong in the central region of the state; this lake acts as a water supply for Sussex County and provides chances for fishing and boating activities. Groundwater and surface water in New Jersey is monitored through the New Jersey Water Science Center, a division of the U.S. Geological Survey. This organization determines whether or not the water is contaminated. The New Jersey Water Science Center monitors over 140 surface water sites throughout the state, such as rivers and lakes, and 30 wells for groundwater.
According to the U.S. Department of Agriculture, New Jersey has over 2.1 million acres of forests, which makes up approximately 42 percent of the state's surface area. Fortunately, the state has not suffered a major loss of trees, since the majority of urban development has been in concentrated areas, such as Greater New York City, Greater Philadelphia and the Jersey Shore. New Jersey has 11 national and state forests regulated by the New Jersey Division of Parks and Forestry. Some of the largest parks in the state include the Delaware Water Gap and High Point State Park, both in the northwestern region of the state. These parks are a boon for New Jersey's tourism economy, since they offer chances for hiking, kayaking and climbing activities.
