The EnviroScape model effectively communicates the shared responsibility for the environment, specifically water quality, to people of all ages. The three-dimensional EnviroScape nonpoint source model focuses on problems caused by nonpoint source pollution and how some of those problems can be mitigated. LDEQâs NPS group usually visits classrooms throughout the year for in-person demonstrations. However, the onset of the COVID-19 pandemic has resulted in the postponement or cancellation of many outreach events.
