It is a degredation product of TCA with fate and transport preperties similar to vinyl chloride and the dichloroethanes, but it is not a carcinogen. Therefore cleanup decisions appropriate for volatile organics will also address this <br />Dibenzofuran. acenaphthylene and phenathrene have no values listed under groundwater standards and do not have surface water standards. They are low molecular weight PAH compounds, therefore cleanup decsisions addressing low molecular weight PAHs will also address these compounds. <br />NL = compound is not listed in the standard <br />NV = compound is listed. but no value is given. <br />a : site specific information on hardness. pH. or temperature is required to calculate some of the standards. Therefore, the actual cleanup level may turn out to be lower for compounds marked with an <br />b : value is calculated using temperature and pH. <br />c : value is calculated using hardness. <br />d : TPH compounds include: 4-isopropyltoluene, 2-methylnaphthalene, 4-methylphenol, n-butylbenzene. n-propylbenzene. sec-butylbenzene. 1.2,4-trimethylbenzene. and 1.3.5-trimethylbenzene. All of these compounds are constituents of petroleum hydrocarbon fuels and solvents, and will be summed and evaluated against the TPH MTCA Method A <br />e : PQLs shown are for Method 8240 which was replaced by Method 8260. <br />f N-nitrosodiphenylamine analysis will include 1.2-diphenyinydrazine and diphenylamine because the chromaticrits of these compounds cannot be separated. For this reason, 1,2-diphenvlhydrazine and diphenylamne have been removed from this and other tables. <br />g Area background concentrations will be determined during the 3-year Evaluation Monitoring period. At the closure of Evaluation Monitoring. revised cleanup levels will be set at area background if higher than PQL or higher than the most stringent of groundwater (drinking water) and surface water standards. <br />h : Metals are dissolved unless otherwise noted Federal Drinking MCLs for metals are total. <br />rw�.ccEv,cwDocmw,n•Tabk�2 Compliance Monitoring and Contingency Plan <br />FINAL - March 2001 Page 2 of 2 Table 2 <br />
