An analytical chemistry investigation using a
Microwave Plasma-Atomic Emission
Spectrophotometer (MP-AES), this project aims
to improve monitoring techniques pertinent to
lead (Pb) contamination in drinking water. Some
studies have indicated that the sampling
techniques used to monitor lead may
underestimate the risk of lead contamination.
First stablishing a method of collection based on
the EPA’s, we sampled drinking water from a
number of locations. Then, by analyzing
samples with the MP-AES, we verify our
determined detection limits by comparison with
Inductively Coupled Plasma Mass Spectrometer
(ICP-MS). Preliminary results should point us to
potential changes in lab methodology. With the
goal of finding a method that would advance
MP-AES detection limits to a place of
confidence; where this instrument (a less costly
option) could be used to get accurate results
comparable to using ICP-MS. The method
developed as part of this research project could
potentially increase access to testing in
communities with higher threats of hazardous
exposure to lead from drinking water.
