EPAThe agency plans to move forward with the development of a regulation for perchlorate to protect Americans from any potential health impacts, while also continuing to take steps to ensure the quality of the water they drink. The decision to undertake a first-ever national standard for perchlorate reverses a decision made by the previous administration. EPA will begin to evaluate the feasibility and affordability of treatment technologies to remove perchlorate and will examine the costs and benefits of potential standards.

Weck Laboratories is certified for testing perchlorate by two different analytical procedures. The routine compliance method utilizes ion chromatography with conductivity detection. The low-level method employs liquid chromatography and mass spectral detection (LC/MS). The LC/MS method offers superior sensitivity, even in difficult and saline matrices

Perchlorate EPA Method Reporting Limit, ug/L Method Detction Limit, ug/L
IC 314.0 2 0.82
LC/MS 331.0 0.1 0.029
