The Senior Environment Corps (SEC) program engages volunteers mostly aged 55 and over. SEC volunteers are engaged in numerous activities from water quality monitoring, stream habitat assessment, storm-drain stenciling, environmental education, community gardening, wildlife surveying, marking abandoned oil and gas wells, and cleaning up parks and trails.
Since 1997, SEC volunteers in Pennsylvania have contributed over 2,000,000 hours, and their contribution is estimated to be of value to the state at over $3 million per year. Coming into 2014, SEC volunteers are active in 20 counties across Pennsylvania, and will soon be expanding into to more areas.
