X, Y: Koordinater i SWEREF 99 TM (används för spatial utjämning)
name: Kortnamn för ämnet, TP = total PFAS
long_name: Ämnets fullständiga namn
group: Ämnesgrupp
value: Koncentration (ng/g våtvikt)
is_censored: TRUE om värdet anges som en övre gräns (detektionsgräns, LOD, eller kvantifieringsgräns, LOQ), annars FALSE
