The calculation for the WQI varies slightly for each monitoring program, as each program uses different measurements. Despite recent reductions in nitrate loads observed at local scales, decreases in nitrate loading from the MRB to the GoM have been small (1.58 % during 2002-2012) with a low level of analytical confidence in this trend. Parking lots may be a significant source of pollution, but up until now there has been no quantitative estimate of the areal extent of parking lots in the U.S. Reducing delivery of nitrate to the Gulf of Mexico is critical to decreasing the size of the “dead zone”—an area of hypoxia, or low dissolved oxygen—in Louisiana coastal waters.

FOIA || water quality either on a national or global level, these rely mostly on normalizing or standardizing data parameter according to expected concentrations (Carr and Rickwood, 2008).The CCME WQI, on the other hand, provides a mathematical framework for assessing ambient water quality The Water-Quality Tracking page provides annually updated information on water-quality concentrations, loads, and trends at sites located throughout the U.S. (2) Objective 2: Water-Quality Changes in the Nation's Streams and Rivers—Outside of the NAWQA Project, the USGS and other Federal, State, and local agencies also have collected long-term water-quality data to support their own assessments of changing water-quality conditions. As per CPCB’s (Central Pollution Control Board) air quality standards, AQI is categorised into six parts. Literature-based average total nitrogen and total phosphorous concentrations were substituted for wastewater treatment levels reported for each facility because little or no concentration data is reported in the CWNS. The attempt was supported by the National Sanitation Foundation (NSF) and therefore as NSFWQI in order to calculate WQI of various water bodies critically polluted. A Water Quality Index (WQI) is a mean to summarize large amount of water quality data into simple terms (e.g., good or bad, clean or contaminated) for reporting to authorities management and the public in a consistent manner.
