The work determined the physicochemical properties and quality of groundwater samples from Industrial cluster areas of Anambra state, Nigeria using Quality Index method. The samples were collected monthly in rainy season (May–July, 2017) and dry season (November, 2017 to January, 2018). The ranges of the physicochemical parameters in both seasons were temperature (27.0–30.4oC), pH (5.5 – 6.5), electrical conductivity (22.5–178 µS/cm), calcium (1.00–17.67 mg/L), magnesium (0.00–13.33mg/L),total hardness (1.00–27.00 mg/L),chlorides (0.83–16.67mg/L), sulphate (0.33–4.00 mg/L), total alkalinity (0.75–16.67 mg/L), total dissolved solids (13.50–106.67 mg/L), total suspended solids (1.03–9.67 mg/L), total solids (16.00–116.33 mg/L), turbidity (0.00–3.04 NTU), dissolved oxygen (5.67–9.07mg/L), biochemical oxygen demand (0.10–1.27 mg/L) and chemical oxygen demand (5.67–18.33 mg/L). The values were compared with the standard values recommended by World Health Organization (WHO 2017) and Nigerian Standard for Drinking Water Quality (NSDWQ 2007). Statistical analysis (ANOVA) was performed which showed significance variations between the parametric values of the borehole water samples. Levene’s t-test indicated significance variations between the rainy season and dry season parametric means. The water quality index (WQI) results in both seasons showed that the water quality status of the samples collected from Uruagu, Nnewichi, Okpoko and Awada were excellent while those collected from Otolo, Umudim, Fegge and Woliwo were good.

Letters pertaining to manuscript published in WES should be sent to the editorial office of WES within three months of either online publication or before printed publication, except for critiques of original research. Following points are to be considering before sending the letters (comments) to the editor.

[1] Letters that include statements of statistics, facts, research, or theories should include appropriate references, although more than three are discouraged.
[2] Letters that are personal attacks on an author rather than thoughtful criticism of the author’s ideas will not be considered for publication.
[3] Letters can be no more than 300 words in length.
[4] Letter writers should include a statement at the beginning of the letter stating that it is being submitted either for publication or not.
[5] Anonymous letters will not be considered.
[6] Letter writers must include their city and state of residence or work.
[7] Letters will be edited for clarity and length.
