TRIANGLE AREA WATER SUPPLY MONITORING PROJECT <br /> INTERLOCAL AGREEMENT <br /> ATTACHMENT A <br /> SUMMARY OF TRIANGLE AREA WATER SUPPLY MONITORING PROJECT <br /> PARTNERSHIP,AUGUST 1988—JUNE 2017 <br /> Due to reliance on surface water for water supply and the potential impact of growth on the <br /> quality of the region's water supply sources, local governments in the region recognize that <br /> water quality monitoring is crucial to the protection of the Triangle Area's surface water <br /> resources. In 1988, a number of local governments in the six-county region, with assistance from <br /> the Triangle J Council of Governments, formed the Triangle Area Water Supply Monitoring <br /> Project to systematically evaluate the quality of several water supply sources in the region. With <br /> assistance from the US Geological Survey (USGS), the Project has collected and analyzed water <br /> quality samples from reservoirs and streams and collected continuous discharge record from <br /> streams in the study area for nearly 30 years. These data, along with data collected by the North <br /> Carolina Division of Water Resources (DWR) and with data collected as part of a program of the <br /> USGS, the US Army Corps of Engineers, and the City of Durham, form a long-term <br /> comprehensive database on the quality of many of the area's water supply reservoirs and rivers, <br /> and selected tributaries to those water supplies. <br /> In the last 30 years, concerns about water quality of the area's water supplies and the impact of <br /> development on reservoir eutrophication and contaminant concentrations have remained <br /> prominent, although specific concerns have changed. Monitoring initially focused on <br /> determining the occurrence of synthetic organic compounds in the water column and bed <br /> sediments; later monitoring and interpretive efforts focused on nutrient and sediment loads and <br /> trends. Issues such as the occurrence of disinfection by-products, microbial pathogens, and <br /> pharmaceutical and personal care products have also been addressed. <br /> Throughout the history of the Project, the local government partnership has leveraged its local <br /> contributions with a major cost share match through a Joint Funding Agreement with the US <br /> Geological Survey. Phase I of the Project began with the execution of an interlocal agreement on <br /> August 18, 1988. At that time, the local government partners consisted of Chatham County, <br /> Orange County, the Town of Apex, the Town of Carrboro, the Town of Cary, the Town of <br /> Chapel Hill, the City of Durham, the Town of Hillsborough, the Town of Pittsboro, the City of <br /> Raleigh, the City of Sanford, and the Town of Smithfield. Phase I concluded in June 30, 1991. <br /> Phase II of the Project began on July 1, 1991 with the execution of an amendment to the original <br /> interlocal agreement. At that time, the local government partners consisted of Chatham County, <br /> Orange County, the Town of Apex, the Town of Carrboro, the Town of Cary, the Town of <br /> Chapel Hill, the City of Durham, the Town of Hillsborough, the City of Raleigh, the City of <br /> Sanford, and the Town of Smithfield. The Town of Pittsboro had left the Project after Phase I. <br /> Phase II concluded in June 30, 1995. <br />
