Description
DESCRIPTION (provided by applicant): New and improved technologies are needed for monitoring perchlorate contamination in groundwater. TDA Research Inc. proposes a new portable sensor platform for in-the-field monitoring of the perchlorate anion, ClO4-, for which the recommended remediation goal is less than 3.6 parts-per-billion (3.6 ppb) in water. Perchlorate is a toxic anion that interferes with the uptake of iodide (a necessary element in thyroid hormones) by the thyroid. This inhibition decreases theproduction of thyroid hormones; thus, exposure to perchlorate needs to be avoided by the developing fetus as well as by infants and children. Perchlorate is highly water soluble, stable, and difficult to detect by chemical or instrumental means. It can betransported by groundwater over long distances, leading to extensive and persistent contamination. Both drinking water sources and food supplies can be contaminated by perchlorate. Therefore, detecting and quantifying perchlorate is a priority for saf
