오덕철,최영찬,고용구 ( Duck Chul Oh,Young Chan Choi,Yong Ku Ko ) 한국하천호수학회 1992 생태와 환경 Vol.25 No.1
The Physical, chemical and bacteriological investigations on the three sites of each two streams, Yeonhee-chun and Donghong-chun which are the sources of two waterfalls, Chonjiyon-Fall and Chongbang-Fall respectively in Seogwipo City, Korea, were carried out monthly from October 1990 to Septermber 1991. The ranges of DO, BOD, SS and SiO_2-Si concentration of Yeonhee-chun were 6.61∼12.82mg/l, 0.1∼4.5mg/l, 0.10∼17.10mg/l and 5.11∼16.22 mg/l respectively, and those of Donghong-chun were 5.30∼11.92mg/l, 0.4∼17.2mg/l, 0.51∼48.67mg/l and 5.16∼14.80mg/l respectively. The result of bacterial investigations for the pollution indicator bacteria such as total coliforms, fecal coliforms, fecal streptococci and others showed that the bacterial quality of Yeonhee-chun was somewhat better than that of Donghong-chun. The MPNs of total coliforms of Yeonhee-chun and Donghong-chun were 750-24×10^4/100 ml and 1100-24×10^5/100 ml respectively, and those of fecal coliforms were 23-24x10^3/100 ml and 9-24×10^5/100 ml respectively. The numbers of fecal streptococci of Yeonhee-chun and Donghong-chun were 2-1,324/10 ml and 3-13,233/10 ml respectively.

서귀포 시내를 흐르며 천지연 폭포수와 정방폭포수를 이루는 연희천과 동홍천을 대상으로 하여 1990년 10월부터 1991년 9월까지 매월 理化學的, 細菌學的 조사를 실시하였다. 理化學的 성분중 DO, BOD, SS 및 SiO₂-Si의 농도범위는 연희천에서 각각 6.61∼12.82㎎/ℓ, 0.1∼4.5㎎/ℓ, 0.10∼17.10㎎/ℓ, 5.11∼16.22㎎/ℓ였으며, 동홍천에서는 5.30∼11.92㎎/ℓ, 0.4∼17.2㎎/ℓ, 0.51∼48.67㎎/ℓ, 5.16∼14.80㎎/ℓ를 나타내고 있었다. 大腸菌群, 糞便性大腸菌群, 糞便性腸球菌, 葡萄狀球菌등 오염지표 세균의 조사결과는 연희천이 동홍천보다 세균학적으로 양호한 상태에 있음을 보여주고 있다. 연희천과 동홍천의 大腸菌群數는 각각 750-24×10⁴/100㎖와 1100 24×10⁴였으며 糞便性大腸菌群數는 23-24×10³개/100㎎ 와 9~24×10 5개/100ml였다. 糞便性腸球菌은 각각 2∼1324개/100㎖와 3∼13233개/100㎖였으며, 葡萄狀球菌은 6∼223개/100㎖와 2∼1042개/100㎖였다. 한편 연희천은 중하류로 갈수록 수질이 나빠지고 있어 周邊域에서의 下水, 汚水가 流入되고 있음을 알 수 있으며, 동홍천은 상류역의 汚濁된 수질이 중, 하류의 수질에 惡影響을 미치고 있었다.

The numbers of fecal streptococci of Yeonhee-chun and Donghong-chun were 2-1,324/10㎖ and 3-13,233/10㎖ respectively.
