Oil and Grease: Past, Present, and Future(?)
Oil and grease is a conventional pollutant that must be monitored for NPDES compliance. There will be a brief recap of the history of Oil and Grease analysis as well
as its inclusion in the “Method Defined Parameter” category. This will be followed by tracing the evolution of instrumentation for the automation of this analysis.

Current AOAC Community Quality Control Initiatives for Water Analysis
The current requirements for water analyses under the Clean Water Act regulations, 40 CFR Part 136, have limited quality control limits specified. The Water and
Wastewater Community has drafted Quality Control measures for the inorganic analyses and are preparing QC controls for microbiological and organic analyses.

Microbiological Quality Control of Water
Quality Control (QC) testing can help identify problem areas such as degraded media or improper training of technicians. The safety of water is paramount to public
health, so quality control is necessary when testing drinking water, public or manufacturing waste water, and environmental water. There are a number of regulatory
agencies and organizations that have set forth guidelines and methods for water testing. QC methods include both presence/absence testing and quantitative testing; a
variety of commercial test kits and controls are available in the marketplace.

One-Step Extraction and Concentration for Identifying Pharmaceuticals and Personal Care Products in Water
Over the last decade the use of Pharmaceuticals and Personal Care Products (PPCPs) has doubled in the United States. As a result, PPCPs have entered the
environment through both human activity and as by-products from manufacturing, agricultural activities, medical use and veterinarian facilities. PPCPs are usually
introduced into the environment through the disposal of unused medications into sewer systems and trash. PPCPs tend to be water soluble and do not evaporate under
normal temperatures, which is why they end up in soil and water. The full effects of PPCPs on the environment are not fully understood and there is concern about
the potential threat they pose to the food chain. Because of the high solubility of most PPCPs, aquatic organisms are most vulner-able. The classes of pharmaceuticals
found in these organisms have been linked to slow growth in frogs and the increased feminization of exposed fish. The scope of human exposure to PPCPs from the
environment is complicated and increased monitoring is occurring to determine the effect on humans of long-term, low-level exposure to PPCPs.
Due to their persistent nature and toxicity, monitoring water sources for PPCPs is a growing priority for both government agencies and consumers. The talk outlines
the fully automated, sample-to-vial extraction and concentration of water matrices for the detection of these compounds in one rapid and efficient process.

An Improved Method for the Determination of Haloacetic acids and Dalapon in Water
EPA Method 552.1 describes an anion exchange solid-phase extraction followed by methylation and GC-ECD detection for the determination of haloacetic acids and
Dalapon in drinking water. In this study, a silica based quaternary amine cartridge with chloride counter ions was used as the anion exchange sorbent. Quaternary
amine is always charged, so sorbent conditioning with acid and base is unnecessary. Acidifying with sulfuric acid is unnecessary and counterproductive as the sulfate
ions will compete with target ions on the sorbent. With this optimized procedure, less solvent and reagent was used and the total analysis time was reduced by 40
minutes per sample when compared with the original EPA method.
