*3.1.5 Soils and water pollution*

Water samples were collected upstream, at the spillway and downstream of the palm oil extraction sites in Ngwéi and Ekondo Titi. Chemical and bacteriological analyses were carried out on 09 water samples. The results revealed contamination and pollution, including even groundwater. Overall the surface waters analyzed are basic with pH values all above the recommendations of the WHO standard for drinking water. Chemical oxygen demands are high and reflect pollution. Suspended matters are present in all samples. In addition, two Ekondo-Titi samples have concentrations of ammonium (NH4 +) ions relatively higher than the recommended value (≤0.50). At the microbiological level, six (06) samples showed concentrations of fecal coliforms not complying with guideline values (0UFC/100 ml). As a result, these waters would be under the influence of a major source of pollution, making them unfit for human consumption without prior treatment. Well water and groundwater are also contaminated.
