Sharptown is located in an agriculturally dominated portion of the Delmarva Peninsula of Maryland. Groundwater quality compliance samples have reflected elevated nitrate concentrations for years. Non-point agricultural sources were thought to be the source of the nitrates, but a detailed study as part of an updated Source Water Protection Plan assessment has now revealed a differing and surprising nitrate source interpretation, for which implementing a remedy is much more feasible.
How does a tourism-dependent community respond to an environmental pathogen found in its water? This session will introduce the basic ecology and pathogenicity of Legionella. A local engineer will share how a large hotel developed and implemented a waterborne pathogen control plan and the local health district will cover their approach to investigating single cases of Legionellosis. Detection and monitoring methods will also be addressed, including a rapid bacteria screening method which provides a means for risk assessment and outbreak mitigation without waiting for a bacterial culture.
A Minnesota study found higher levels of ammonia and total organic carbon than expected in groundwater sources. During this session, we will identify the issues ammonia can cause in water distribution systems and develop a free ammonia management, disinfection, and/or nitrification control strategy to minimize undesirable consequences caused by these contaminants.
An analysis of drinking water contamination at both the community and household level was conducted in Shatila camp, Lebanon. To ascertain the health impacts of water contamination in children under five, questionnaires were used to elicit community and household practices as well as child health indicators. Results, suggested interventions, and risk communication and targeted health education will be discussed in the context of human rights and marginalized populations.
