Perchlorate: a growing concern

What’s it all about?
Found in rocket fuel, explosives, airbag inflators, leather finishing, and fertilizers, perchlorate is very mobile in the environment, persistent in aqueous systems, and very difficult to treat. Releases have been identified in 18 states, and there is growing concern that even small amounts may cause thyroid tumors, decrease thyroid function, and adversely affect neurological growth and development in fetuses and infants. With the need for perchlorate investigation and characterization increasing, Lancaster Labs provides years of pertinent analytical expertise to this ever-growing environmental concern.

Are you prepared?
Perchlorate has been placed on the Contaminant Candidate List (CCL) and on the Unregulated Contaminants Monitoring Rule (UCMR). Consequently, numerous projects are being conducted to determine the extent of perchlorate occurrence in the environment, and several states have adopted various advisory limits, including:

Arizona 14 µg/L
California 4-14 µg/L
Massachusetts 1 µg/L
Nevada 18 µg/L
Texas 4 µg/L


Based on the current provisional reference dose (RfD) range, the EPA suggests using a preliminary remediation goal of 4 to 18 µg/L.

How we can help
Lancaster Labs has extensive experience performing perchlorate analysis for Method 314 by IC to obtain the following limits:

Method Detection Limit
(MDL) 0.7 µg/L
Limit of Quantitation
(LOQ) 4.0 µg/L

And for Method 8321 by LC/MS/MS, which yields better sensitivity and selectivity.

Method Detection Limit
(MDL) 0.2 µg/L
Limit of Quantitation
(LOQ) 1.0 µg/L
