Analysis of organic compounds in surface water.

High levels of organic contaminants are not found in surface water unaffected by human activity. Elevated levels of such contaminants is a result of short or long range transport from contamination sources.

Method & reporting limits

ALS Environmental can provide analytical testing for Microcystin-LR (MC-LR) in water to reporting limits of 5ng/L using an accredited method developed in-house. MC-LR is a naturally occurring toxin produced by cyanobacteria that has been shown to possess toxic and carcinogenic properties and has been detected in drinking water supplies in the low parts-per-trillion (ng/L) range.
