Potable Water Reuse – Navigating the Analytical Requirements for Monitoring

In the last dozen years, potable water reuse, including direct potable reuse (DPR) has become much more important across the US. The challenges associated with potable reuse are not just the need for more complex treatment processes than conventional water treatment plants, but also include the development of monitoring plans that reflect a myriad of different state requirements.  Equally important is the challenge of accurate and precise analytical results for drinking water regulated analytes and process performance indicators or specific sewage derived contaminants.  This becomes particularly important when the matrices are not typical “drinking water” (e.g. wastewater effluent or partially treated water). To demonstrate adequate treatment, it is necessary to have accurate analyses in both finished water and these more complex matrices.

This webinar will review the general types of monitoring required for potable reuse and more specifically address the analytical methods that are available to meet the data quality objectives, focusing on the drinking water regulated constituents requiring monitoring under the Safe Drinking Water Act. For these constituents, the methods in finished water are mandated, but those methods are not designed for the more complex reuse methods, so alternative analytical approaches are required.
