A municipal well shows coliform bacteria; what does this indicator most directly imply about health risk?
A
Possible fecal contamination and increased risk of enteric pathogens, because coliforms suggest sewage or animal waste intrusion.
B
Certain presence of malaria parasites, because coliforms are required hosts for Plasmodium in groundwater systems.
C
No concern, because coliform bacteria are always harmless and guarantee that water is safe to drink.
D
Heavy metal contamination, because coliforms metabolize lead into detectable colonies on standard water tests.
