Variation in Groundwater Qaulity Parameters in the Vicinity of a Waste Dumpsite in Eneka, Rivers State, Nigeria

ABSTRACT

The quality of groundwater impacted by a waste dumpsite in Eneka, Rivers State was studied using temporal approach. Groundwater samples were collected and analyzed for 27 parameters using standard methods. Water samples were collected with 250mL plastic containers from seven sampling boreholes. Samples for heavy metals were fixed with concentrated HNO3 in the ratio of 2:500. The descriptive statistics, one-way ANOVA, means plots, variation plots and student’s t-test were used to analyze data. Water temperature varied from 25.00-26.10 (25.52 ± 0.08)oC, pH varied from 6.80-7.33 (7.00 ± 0.04), and DO varied from 4.80-6.60 (6.14 ± 0.10))mg/L. TDS (5.50mg/l), Electrical conductivity (14.0) and water temperature (25.5oC) contributed significant heterogeneity in levels of the quality parameters measured across the sampling boreholes (Sig.t=0.000) at P
