Mikrobiologiska vattenundersökningar

Mikrobiologiska vattenundersökningar – Rent vatten är en av våra viktigaste naturtillgångar, och en förutsättning för mänskligt liv. Det är därför nödvändigt att vi övervakar och skyddar våra gemensamma vattenresurser från olika föroreningar. Standardiserade metoder för provtagning och analys är ett viktigt verktyg som underlättar kontrollen av vattenkvalitén.

Standarderna inom området vattenundersökningar behandlar fysikaliska-, kemiska-, mikrobiologiska- och biologiska undersökningar av olika typer av vatten (t.ex. grundvatten, ytvatten, dricksvatten och avloppsvatten). Inom området har det publicerats fler än ett hundratal svenska standardmetoder, varav många överensstämmer med internationell standard. Det svenska standardiseringsarbetet sker i tre tekniska kommittéer:

• Kemiska vattenundersökningar

• Mikrobiologiska vattenundersökningar

• Biologiska vattenundersökningar
