[edit] History
In 1608 the area was settled by Massawomecks and Susquehannocks.[1] The first European to see the area was John Smith in 1608 when he traveled up the Chesapeake Bay from Jamestown.[1] In 1652, the English and Susquehannocks signed a treaty at what is now Annapolis for the area now called Harford County.[1] Harford County was formed on March 22, 1774 from the eastern part of Baltimore County with a population of 13,000 people. On March 22, 1775, Harford County hosted the signers of the Bush Declaration, a precursor document to the American Revolution.[1] On January 22, 1782, Bel Air became the county seat.[1] Havre de Grace, a city incorporated in 1785 within Harford County, was once under consideration to be the capital of the United States rather than Washington, D.C.[1] It was favored for its strategic location at the top of the Chesapeake Bay; this location would facilitate trade while being secure in time of war. Today, the waterways around Havre de Grace have become adversely affected by silt runoff, which is one of the primary environmental issues of Harford County. While today the site is a Maryland National Guard military reservation, the land was used as the Havre de Grace Racetrack where racehorse Man o' War ran in 1919 and 1920.
In 2011 the Office of National Drug Control Policy deemed Harford County a designated High Intensity Drug Trafficking Area. The county was named for Henry Harford (ca. 1759–1834), the illegitimate son of Frederick Calvert, 6th Baron Baltimore. Henry Harford was born to Calvert's mistress, Hester Whelan, whose residence still stands as part of a private residence on Jarretsville Pike, in Phoenix, Maryland. Harford served as the last Proprietary Governor of Maryland but, because of his illegitimacy, did not inherit his father's title.[1] There are 79 properties and districts listed on the National Register in the county, including one National Historic Landmark called Sion Hill. [edit] Environmental historyHarford County has environmental issues in three major areas: land use, water pollution/urban runoff, and soil contamination/groundwater contamination. As the county sits at the headwaters of the Chesapeake Bay along the Susquehanna River, it plays a key role in controlling sediment and fertilizer runoff into the bay as well as fostering submerged aquatic vegetation (SAV) regrowth. The county has had to balance the needs of land owners to practice agriculture and/or pave land (creating impervious surfaces) with effects of runoff into the bay. Harford County has been burdened by soil contamination and groundwater contamination since the creation of the Aberdeen Proving Ground in 1917. The military installation performs research for the U.S. Army, including weapons testing, and has released various chemical agents into soil and groundwater, including mustard gas and perchlorate. The bordering towns of Aberdeen, Edgewood and Joppatowne have been affected by this contamination. Aberdeen Proving Ground contains three Superfund priority sites . Groundwater contamination by MTBE, a mandatory gasoline additive, has also affected Fallston. Harford County also faces controversy from residents living near Scarboro Landfill and Harford Waste Disposal Center, the only municipal landfill. The landfill, approved to triple in size in 2007, is the subject of complaints by neighbors of operating violations, such as large areas of open trash and blown litter; leachate breaks which contaminate area residential wells and flow into Deer Creek, a tributary of the Susquehanna River; and increased health problems.
