H
hydrology - the study of water and how it moves and is distributed in the environment
L
legacy pollutant - chemical introduced to the environment in the past which may be banned from production in present day, but still persists in the environment because of its stable characteristics
M

P
persistent - description of a chemical that does not break down in the environment over extended periods of time through normal chemical, biological, and physical processes and so remains a potential threat to human health and the environment
