Logam berat Mangan (Mn) termasuk logam esensial yang bersumber dari peristiwa pengikisan (erosi) Mn masuk kedalam lingkungan perairan akibat dari aktivitas manusia seperti buang limbah industri, pelayaran, pertanian dan buangan limbah rumah tangga. Penelitian ini bertujuan untuk mengidentifikasi sebaran spasial logam berat Mn di Perairan Teluk Staring. Jenis penelitian yang di lakukan adalah pengambilan sampel air laut di permukaan Teluk Staring sebanyak 12 Stasiun dengan metode Purposive Random Sampling. Larutan sampel dianalisis dengan Spektrofometri Serapan Atom (SSA). Analisis sebaran spasial menggunakan metode interpolasi IDW pada ArcGIS. Dari hasil pengukuran menunjukan kisaran kosentrasi kadar logam Mn di 12 Stasiun sebesar 0,1153 dan 0,4077 ppm. Nilai rata-rata logam Mn adalah antara 0, 2463 ppm. Kadar logam Mn yang tertinggi terdapat pada Stasiun 3 dan 4. Hasil analisis spasial dari 12 Stasiun menunjukan bahwa pada semua stasiun pengamatan telah  terkontaminasi oleh logam berat Mn, dengan konsentrasi melewati standar baku mutu yang telah ditentukan oleh ENVIRONMENTAL PROTECTION AGENCY, Water Quality Standard 1972. Dalam hal ini Teluk Staring telah tercemar oleh logam berat Mn. Sedangkan variabel lingkungan (Suhu,Salinitas dan pH) terhadap konsentrasi Logam Berat Mn tidak memiliki pengaruh yang signifikan.Kata kunci: Logam Berat Mangan (Mn), Distribusi Spasial, Teluk Staring

Water Quality Standard

Cimanuk river is one of the seven rivers in West Java. Cimanuk river pollution is indicated to have suffered as a result of the activity of domestic waste, industrial and agricultural uncontrolled in the riparian area of Cimanuk river. This research aims to analize water quality of Cimanuk river based on water quality standard on Government Regulation of Republic of Indonesia (IDN), Regulation of the Governor of West Java (WJ), World Health Organization (WHO), Enviromental Standard of United Kingdom (UK), Environmental Protection Agency (EPA), Enviromental Quality Standard (EQS), and Department of Environment (DOE). This research used pollution index method. The result is water quality of Cimanuk river not meet water quality standard where the TSS (94.85±84,60 mg/L), BOD (9.61±3.16 mg/L), COD (37.69±14.01 mg/L), DO (5.12±1.22 mg/L), NH3N (0.25±0.24 mg/L). Degradation of water quality of Cimanuk river from upstream to downstream marked by increased pollution index value annually. Pollution index of Cimanuk river ranging from 1.25 to 20.31. Water quality status of Cimanuk river has been from lightly polluted to heavilypolluted.

The Impact

ABSTRACT The frequency of poor-water-quality advisories issued in Milwaukee and Racine, Wisconsin, in the absence of identifiable sources of contamination brought into question the reliability of the present indicator organism, Escherichia coli. Enteroccoci have been suggested as an alternative to E. coli for freshwater monitoring due to their direct correlation to swimmer-associated gastroenteritis. The purpose of this research was threefold: (i) to explore enterococci as an alternative to E. coli for monitoring freshwater Lake Michigan beaches, (ii) to evaluate the impact of the two indicators on regulatory decisions, and (iii) to compare membrane filtration m-enterococcus agar with indoxyl-β-d-glucoside to a chemical substrate technique (Enterolert) for the recovery of enterococci. Recreational water samples from Milwaukee (n = 305) and Racine (n = 153) were analyzed for the enumeration of E. coli and enterococci using IDEXX Colilert-18 and Enterolert. Correlation between the indicators was low (R 2 = 0.60 and 0.69). Based on U.S. Environmental Protection Agency bacterial indicator threshold levels of risk for full body immersion, using enterococci would have resulted in 56 additional unsafe-recreational-water-quality advisories compared to the total from using E. coli and the substrate-based methods. A comparison of the two enterococcal methods (n = 124) yielded similar results (R 2 = 0.62). This was further confounded by the frequent inability to verify enterococci from those wells producing fluorescence by the defined substrate test using conventional microbiological methods. These results suggest that further research is necessary regarding the use of defined substrate technology interchangeably with the U.S. Environmental Protection Agency-approved membrane filtration test for the detection of enterococci from fresh surface water.

Transfer Programs

Technology transfer is an important activity within the ll.S. Environmental Protection Agency. Specific technology transfer programs such as the activities of the Center for Environmental Research Information, the Innovative and Alternative Technology Program, as well as the Small Community Outreach Program are used to encourage the utilization of cost-effective municipal pollution control technology. Case studies of three technologies including a plant operations diagnostic/remediation methodology, alternative sewer technologies and ultraviolet disinfection are presented. These case studies are presented retrospectively in the context of a generalized concept of how technology flows from science to utilization which was developed in a study by Allen (1977). Additional insights from this study are presented on the information gathering characteristics of engineers and scientists which may be useful in designing technology transfer programs. The recognition of the need for a technology or a deficiency in current practice are important stimuli other than technology transfer for accelerating the utilization of new technology.
