Abstract
Purpose: Wastewater from abattoirs, municipal,
agricultural and industrial effluents is a major source
of environmental pollution as they consume large
amounts of fresh water for meat processing and
hygienic purposes. The main objective of the study
was to assess the quality of the effluent from
Keekonyokie and Kiserian slaughterhouses and its
effect on the quality of water in Kiserian dam.
Methodology: The parameters measured were pH,
total suspended solids, total nitrogen, total
phosphorous, dissolved oxygen and fecal coliforms
(E. coli). Samples were collected from 4 sampling
sites three times a week for three months. SPSS
(ANOVA) for their significant differences. Onesample t-test used to compare the parameter means
with NEMA 2006 standards. Pearson Correlation used
for correlation among the parameters.
Findings: The mean fecal coliforms 2215.206 mg/l,
Phosphorous 47.379 mg/l, Nitrates 36.71 mg/l, TSS
387.57 mg/l which were above the standards of
NEMA 2006 of nil, 2, 2 and 30 mg/l respectively while
DO was 8.58 mg/l and pH 6.86-7.0 both of which were
below the NEMA 2006 standards of 30 mg/l and 6.5-
8.5. The results of all parameters were significantly
different among the sites (p=0.00). There was
significant difference between the parameters and the
NEMA 2006. ANOVA results on parameters showed
the all coliforms increased with increase in rainfall
with the highest levels in September with a mean
18662.7 mg/l and in July with the lowest of 12962.5
mg/l.
Unique Contribution to Theory, Practice and
Policy: The study can be used by slaughterhouses
developers and management on slaughterhouse
wastewater treatment. To be used by slaughterhouses
licensing authorities on SWW requirements before
licensing. To be used by Public Health Department for
disease surveillances and Water Regulatory
Management Authority on domestic water treatment.
