Determination of Pesticide Residue in Dug Well and Borehole in Yawa Drinking Water Adamawa State, Nigeria
Abstract
This
research work is aimed at determination of pesticide residue in dug well and
borehole in Yawa drinking water. In this work, water
samples collected from Yawa Mubi South Adamawa State were analyzed for
physicochemical parameters. After sample collection and extraction, some heavy
metal concentrations (Cadmium, Zinc, Iron, Copper) were determined using Atomic
Absorption Spectroscopy (AAS) in the water samples and their levels compared
with WHO/FAO maximum levels. Gas
Chromatography/Mass Spectrophotometer was used to determine the levels of
pesticide residues in the water samples. The temperature of water samples was
between 24.0 (Kofan Jauro well 25.00c) and (Yawa community
borehole). All water samples were alkaline with pH ranging from 5.07 (Yawabetenga
borehole) to 5.46 (Yawa primary well). Yawa primary well showed the highest
turbidity (155.3 ± 1.53 NTU), the least turbidity was (1.33
± 1.55 NTU) observed in Yawa community borehole. The maximum level of TDS
was131 ± 1mg/l which was detected in KofanJauro well. The least concentration
(12.0 ± 1.01mg/l) of TDS was detected in Yawa primary well which also showed
the highest electrical conductivity (226 ± 1A). Yawabetenga borehole showed the
least EC (135 ± 1A). Cadmium values ranges from 2.79-3.59 mg/L,
cadmium was not detected in KJW and YBB. All the values analyzed for cadmium
were found to be above the allowable limit set by EPA, 2018. All the values
analyzed for Zn are extremely above the standard set by EPA, 2018. The highest
concentration of aldrin was detected in Yawa borehole and the lowest
concentration was detected in KofanJauro well. The maximum concentration of
pesticide Endosulfan (4.46266 mg/L,) was
detected in Yawa Primary well. The least of all detected pesticides is
methoxychlor (0.001852 mg/L) in Yawa borehole near River. Heptachlor however
was not detected completely in water sample from Yawa borehole near river, Yawa
Betenga Borehole and Yawa borehole. P, p’ – DDE was not detected in Yawa
borehole near river. Water samples from Yawa primary well showed elevated
concentration of pesticides (>0.1mg/L) relative to water samples from other
wells and boreholes from Yawa Mubi South.
