Matlab program for lambda iteration method11/14/2022 ![]() ![]() The propagation of radio wave through metallic structures which often suffers signal attenuation has been a major concern to both the network engineers and the subscribers. As such, it was concluded that downstream water of Iba Oku stream is highly contaminated due to the influence of Akpayakwaste dumpsite. ![]() Also, mean total heterotrophic bacteria was 6.4 while mean total coliform count was 126.7 indicating high faecal contamination of the downstream water which can cause serious health hazard like malaria, typhoid fever etc. Values for Coefficient of Determination (R2) were 1.00, 0.97, and 0.97 for Na, DO and COD respectively indicating that Na, DO and COD contents of downstream water were significantly different from Na, DO and COD at the waste dumpsite. Their frequency calculated (Fcal) values were as follows: Na (223.79), DO (156.52) and COD (426.39). ![]() The results showed that mean of Na (27.46), DO (1.73) and COD (23.91) at waste dumpsite were significantly different from that of downstream water with mean of Na (20.79), DO (18.96) and COD (12.19) respectively. The statistical analysis showed that quality of leachate from waste dumpsite greatly affected the downstream quality of Iba Oku stream particularly, in Na, DO, and COD content of the downstream water. The results from the laboratory were analyzed statistically. These samples were subjected to laboratory analysis using standard procedures for chemical and biological parameters at the University of Uyo Central Laboratory. Samples of leachate were collected using standard procedures at the waste dumpsite together with samples of water mixed with leachate at upstream and downstream of the adjourning stream. ![]() This research was carried out on evaluating the quality of leachate from Akpayak waste dumpsite and the effects of its effluent on downstream of Iba Oku stream along Uyo Village Road, Uyo. ![]()
