his study investigated the physicochemical parameters and bacteriological quality in hand dug wells in Lafia metropolis
of Nasarawa State. A total of five selected hand dug wells samples were analyzed using standard methods. The observed
physiochemical parameters were temperature, pH, electrical conductivity, total hardness, total dissolved solid (TDS), total
suspended solid (TSS), total solid (TS), nitrate NO
3
-, phosphate PO

- and chloride (Cl-). The results of the physicochemical
parameters ranged as follows: Temperature (28-30ºC), pH (4.71-6.85), conductivity (28-825 µs/cm), total hardness (45-78
mg/L), TDS (18-550 mg/L), TSS (0-490 mg/L), Cl- (10.77-79.85 mg/L), NO

- (143.66-656.44 mg/L) and PO

- (0.271-7.4
mg/L). NO

- in water exceeds the WHO standard for drinking water, parameters such as total hardness, total dissolved solid,
total suspended solid, total solid, chloride, and electrical conductivity had some sample exceeding the WHO standard while
others were below the WHO standard. The bacteriological analysis carried out on the water shows that, none of the samples
complied with bacteriological standards as total aerobic counts, generally exceeded permissible limit of 100 CFU/ml for
coliform count and 1.0 X 10
2
CFU/ml for bacteria and pathogen count such as
Escherichia coli, Pseudomonas aeruginosa,
Staphylococcus aureus, Staphylococcus
spp
., Serratia marcescens, Proteus
spp
. and Micrococcus
spp. counts were very high.
