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.
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.
This group of compounds can act as reliable indicators of contamination or disturbances.
MORE INFORMATIONUndesirable organic compounds should typically not be found in surface water unless there are sources contributing to contamination.
MORE INFORMATIONLevels of metals, and in particular heavy metals, is a crucial part when monitoring surface water quality.
MORE INFORMATIONHigh levels of certain microbes in surface water are an indicator of possible drainage from nearby areas.
