Determine the volume (m3) of fractured bedrock that can potentially be contaminated with one drum of dnalp (205 l). assume the fracture porosity ranges from 0.001 to 0.01. also assume dnapl will occupy 20% of fracture space.

Mexico has a host of environmental problems, including significant chemicalpollution  from factory discharges and waste dumping, but the main threat to itsbiodiversity  probably stems from  deforestation  and other natural habitat losses. forest habitat is lost for a number of reasons
