환경 보호국(DEP)가 2014 펜실베니아 통합 수질 모니터링과 국가의 만, 개울, 강, 수로의 전체적인 수질을 평가한 평가 보고서를 발표했다.

환경 보호국은 모든 표면수의 4가지 보호 사용을 평가했다. 4가지는 어류 소비, 식수의 재창조, 수중 생물을 평가하고 수화학 처리, 미세한 무척추 동물, 병원균, 철분, 질산염, 황산염을 조사했다. 연방 수질 오염 방지법에 의해 2년마다 요구되는 보고서는 보호 사용을 위한 손상된 수로의 목록화나 명단 삭제를 목적으로 한다. 올해에 두 개 목록이 모두 변화했다.

the Department of Environmental Protection (DEP) released the 2014 Pennsylvania Integrated Water Quality Monitoring and Assessment Report, providing an assessment of the overall water quality of the state's many creeks, streams, rivers, and waterways.

DEP assesses four protected uses of all surface waters: fish consumption, recreation, potable water, and aquatic life, as well as examines water chemistry, macro-invertebrates, pathogens, iron, nitrates, and sulfates. The report, required every two years by the federal Clean Water Act (CWA), proposes listing or delisting waterways as impaired for the protected uses. This year there are two listing changes.

The Monongahela River, which was impaired for potable water use, will be removed from the impairment list because the in-stream level of sulfates now meets Pennsylvania's water quality standards. The lower main stem of the Susquehanna River will be added to the fish consumption impairment list for channel catfish larger than 20 inches due to Polychlorinated biphenyls (PCBs). The recommended consumption is no more than one meal per month.

Accordingly, DEP has conducted a comprehensive analysis of the Susquehanna River since 2012 and continues to do so in 2014. The 2013 Susquehanna River Study Report will be available in mid-May. A public webinar will take place at that time to discuss the results.

The Integrated Waters Report is now open for a 45-day comment period. After the comment period, comments will be reviewed by DEP, changes will be made and a comment response document released. DEP's final draft of the report will be sent to the U.S. Environmental Protection Agency for approval.

Public comments on the report are encouraged. The comment period will begin on April 26 and continue until June 10. Written comments should be submitted to Molly Pulket, Division of Water Quality Standards, Bureau of Point and Non-Point Source Management, P. O. Box 8774, Harrisburg, PA 17105-8774 or via email to RA-WQAssessments@pa.gov. Comments received by facsimile will not be accepted.
