Description:

This SBIR addresses EPA’s need for improved sampling and analysis technologies to

detect Per- and Polyfluoroalkyl Substances (PFAS). PFAS are used in firefighting sprays, at

airports, and for wild fires, and have been used in textile treatments (e.g., it is a component

in Scotchgard). It is estimated that 65 million Americans are at risk of PFAS exposure in

their drinking water. Seacoast proposes a product to reduce cost per-sample analysis by

implementing a disposable cartridge and optical detection. The cartridge will contain the

necessary chemicals to convert PFAS in a water sample to optically active species detected

using portable spectrophotometry. The cartridges are one-time-use plastic (injection

molded) components containing reagent pouches, microfluidic channels, and a reaction

chamber. The instrument will have an automated test procedure that coordinates reagent

injection and analysis using UV light activated absorbance/fluorescence allows detection

and quantification. This system combines inexpensive detectors, specialized chemistry, and

microfluidics to simplify PFAS analysis, reduce cost-per-sample, and allow portability to

remediation field-sites. Cartridges will cost under $100 per test, and high throughput,

allows lower cost per sample than traditional analysis. Annual revenues of $6M are

projected if the product is used for just 1% of the US public drinking water systems.
