# Abstract A study of analytes for ground water monitoring was conducted at 10 municipal solid waste landfills in northern New South Wales (NSW), Australia. From literature review, analytes were proposed and then approved by the NSW Environment Protection Authority (EPA) for initial ground water and leachate monitoring. Eight rounds of initial baseline monito ring using traditional geochemical analytes were co nducted in uncontaminated ground water at a new, li ned landfill. Four rounds of initial assessment monitor ing were conducted at nine unlined or only partiall y lined old landfills. Analytes for the old landfil ls were selected with a health risk emphasis because groundwater may already be contaminated. At the old landfill sites, analytes with values ind icating contamination were often limited to one particular analytical group, although the analytical g roup represented differed from site to site. As a result , the most environmentally responsible suite of ana lytes for baseline monitoring is the traditional ge ochemical approach; free carbon dioxide for landfill gas; and organics in the form of volatile organic compounds for old landfills, but benzene, toluene, ethylbenz ene, and xylene when wells are close to a new landfill. The current Subtitle D (U.S. EPA 1991) analytes pro ved inadequate. They would not have detected the majority of contaminants or contaminant indicators at the old landfills, i.e., organic nitrogen, ammon ia, nitrate, iron, and manganese. After completion of initial monitoring at each site , reduced lists of analytes for ongoing monitoring were proposed and approved by the NSW EPA. The list s were based on literature evidence, contaminants, an d contaminant indicators found in ground water at the old landfills, and in some cases leachate versus ground water concentrations. For the new landfill, the principle of limited analytes representing a br oad range of analytical groups was used to assure precautionary environmental outcomes. At present-da y costs, cost savings for analyses alone at the newlandfill are ÄD251, 160 over the 70-year life of the landfill. Get PDF (812K) (/doi/10.1111/j.1745-6592.2003.tb00677.x/pdf)
