Case Studies of a Hydrocarbon Capture Technology for Stormwater Quality Class 1 Compliance against EN BS858.1-2002 and Subsequent Field Evaluation

Abstract

Abstract:Hydrocarbon spills and management in the marine environment are of significant environmental and public health concern and the subject of many research projects. In freshwater environments the treatment and management of hydrocarbons from point and diffuse sources appears less well investigated. For hydrocarbon treatment technologies introduced into the European market, they must be tested and comply with the requirements of the European Standard EN BS858-1-2002. This Standard requires laboratory testing of full-scale models. Testing of several models of a hydrocarbon capture technology was performed in accordance with EN BS858-1:2002 at the HR Wallingford, United Kingdom (UK) and repeated at the University of South Australia (UniSA) laboratories. The results of the laboratory testing demonstrated compliance with the Standard's Class 1 criteria of less than 5 mg/L of hydrocarbons in the effluent. Field testing of several installations of the hydrocarbon capture device in Australia has also confirmed outlet concentrations conforming to the Class 1 requirement of <5 mg/L hydrocarbons.

“…The New Hampshire Department of the Environment recommends that stormwater should not be permitted to flow over the gas station refueling zones [14], presumably because the stormwater can pick up spilled fuel and then contaminate downstream water bodies. Indeed surface runoff from gas stations has been found to be contaminated by fuel constituents [15,16].…”
