W badaniu przeanalizowano wlaściwości ścieków odprowadzanych z garbarni w Etiopii. Próbki ścieków pobrano w miejscu odprowadzania w celu określenia parametrów fizykochemicznych. Stężenie chromu (3+) w ściekach określono za pomocą SLC 208. Analiza TSS, COD, Cl, amoniaku, siarczków i fosforanów w ściekach zostala również przeprowadzona w laboratorium przy użyciu metod APHA2540-D, APHA 5220 B-COD, APHA 4550-Cl-B, APHA 4500-NH3, SLC 202 i Hack Lange (LCK349). Średnie wartości poszczególnych parametrów ścieków porównano z wartościami normatywnymi określonymi przez Ministerstwo Środowiska, Lasów i Zmian Klimatu. Wyniki dla Cr(3+), pH, TSS, COD, Cl, amoniaku, siarczków i fosforanów wynoszą odpowiednio 27,6 mg/litr, 7,63 jednostki pH, 631,4 mg/litr, 1597,9 mg/litr, 2493 mg/litr, 111,2 mg/litr i 52,35 mg/litr i 0,78 mg/litr. Wyniki wszystkich parametrów z wyjątkiem pH i fosforanów byly powyżej wartości normatywnych ustalonych przez Ministerstwo Środowiska, Lasów i Zmian Klimatu. Wyniki badania wykazaly, że parametry fizykochemiczne ścieków odprowadzanych z garbarni zawierają wysokie stężenie zanieczyszczeń i mają wplyw na zdrowie ludzi oraz ekosystem wodny.
