Swimming Pool Regulations: Both Sides of the Cyanuric Acid Stabilizer Debate

The Model Aquatic Health Code is published, but many in industry and public health think that the code did not set the correct limits for cyanuric acid. Some believe it is too restrictive and others believe it is not restrictive enough. This presentation is intended to provide you with the information you need to join the debate in the Conference of the Model Aquatic Health Code to help provide reasonable limits for cyanuric acid that are protective of public health.

Nitrates in Rural Groundwater Not From Farming; An Unexpected Finding Based on Forensic Geochemistry

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.

Innovative Methods to Control, Investigate, and Monitor for Legionella: A Panel Discussion

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.

Identification and Implementation of Effective Educational Campaigns for Private Well Testing

Why don’t many private well owners test their wells? The results from a nationwide evaluation of private well owner outreach programs will be shared. A number of successful approaches will be discussed to provide the audience with an assessment of the criteria used to evaluate how and when each approach should be used as part of a private well testing educational campaign. Attendees will leave with a roadmap for how to create a successful private well testing program.
