Answer #1

The maximum contaminant level ( MCL ) for groundwater is 0.004 mg/L or 4 ppb .

The effect of beryllium on human health are -

1) Exposure of beryllium to human skin may cause skin problems as well as many skin allergies .

2) Ingestion of beryllium may cause irritation in eyes , nose , throat .

3) chronic beryllium disease ( CBD ) is the most common disease caused due to exposure of beryllium . CBD is a T-cell meditated disorder.
