Ambient monitoring measures the status of air quality throughout the state to assess trends, compliance with federal and state air quality standards, effectiveness of control strategies and attainment plans, health effects and environmental damage; respond to citizen complaints; evaluate specific geographic or hot-spot air quality concerns; and create environmental indicators. Emission inventory is the cataloging of sources of air pollution and the emissions from those sources. Inventory data are critical to the understanding of the causes of air pollution problems and creation of appropriate solutions. Meteorological forecasting and dispersion modeling of air pollutants are essential to understanding the movement and buildup of air pollution; the carrying capacity of airsheds; the interaction of pollutants; and the location of maximum impact of sources of pollution. As of September 26, 2005 there are no longer any areas of Washington designated as "NONATTAINMENT."

The Petroleum Storage Tank Bureau works to reduce, mitigate and eliminate the threats to the environment posed by petroleum products or hazardous material or wastes released from underground and above ground storage tanks. This is accomplished by: -Preventing leaks and spills through equipment, monitoring, testing, installation, removal and other requirements, which are enforced through inspections. -Requiring corrective action such as repairing or closing the tank system and cleaning up the spill or leak. -Adhering to the regulations governing owners and operators of petroleum storage tanks located in 20.5.101-20.5.125 of the New Mexico Administrative Code.

This dataset shows Near Surface Nitrate Susceptibility. Pollution Impact Potential (PIP) maps were generated separately for nitrate and phosphate to rank critical source areas (CSAs) relative to one another from diffuse agriculture for both the groundwater and surface water receptor. The PIP maps are generated by the EPA Catchment Characterisation Tool (CCT). The CCT delineates the CSAs displayed in the PIP maps by overlaying the hydro(geo)logically susceptible areas (the likelihood of nutrient transfer due to soil and geological properties along the near surface and/or subsurface pathway) with nitrate or phosphate loadings. The nitrate and phosphate PIP maps for the surface water receptor combine the contribution from both the subsurface pathway and the near surface pathway while the groundwater receptor maps only consider the contribution from the groundwater pathway. Surface Water Receptor Nitrate PIP map shows the relative pollution impact potential to surface water along the subsurface and near surface pathways due to nitrate loading. This map should be used to evaluate nutrient impact at the waterbody, subcatchment or catchment scale (at a resolution of less than 1:20,000). Pollution impact potential (PIP) maps rank the CSAs in descending order of risk (where Rank 1 is the highest risk) and are available for the surface water receptor for nitrate and phosphate, and the groundwater receptor for nitrate. Local pressure data has been used to generate the maps in agricultural areas where available. For urban, forestry and the remaining agricultural areas, regional sources of pressure data have been used; these areas are marked 'using regional loadings' on the PIP maps.

The amount of wastewater leaving the treatment works is measured and often referred to as ‘flow’. If there’s heavy rain, the sewer network may struggle to cope with the amount of wastewater and rainwater in it. The screened wastewater, which can be around 95% rainwater, is released through storm overflows. The storm overflows act as a pressure valve to release excess water through outfalls into rivers and the sea. This protects homes and communities from flooding. Releases from storm overflows are called spills. Flow data is reported every year to the Environment Agency.

The annual reports show the number of times storm overflows were active and for how long, as indicated by EDM monitors. This is updated by mid-March with data from the previous calendar year.

This map provides near real-time information about storm overflow activity, as indicated by event duration monitoring (EDM). You can use the map to see if the EDM monitors indicate: i. that overflows are currently discharging into a watercourse Ii. the date and time of the last recorded discharge. The data received from the EDM monitors isn’t always accurate. It doesn’t confirm discharges, it only indicates them. Thames Water is being open and sharing that data exactly as it receives it, so you can make more informed decisions.

The Scottish Pollutant Release Inventory (SPRI) is a Pollutant Release and Transfer Register (PRTR) and has the primary purpose of making publicly available officially reported annual releases of specified pollutants to air and water from SEPA-regulated industrial facilities.

In 2021, WHO published the updated global Air Quality Guidelines, providing recommendations on air quality guideline levels as well as interim targets for six key air pollutants - particulate matter, ozone, nitrogen dioxide, sulphur dioxide and carbon monoxide. In addition, good practice statements are included.The new guidelines provide clear evidence of the damage that air pollution inflicts on human health, at even lower concentrations than previously understood. The guidelines identify the levels of air quality necessary to protect public health worldwide, and serve as a reference for assessing if, and by how much, the exposure of a population exceeds levels at which it causes health concerns.Achieving the recommended air quality guideline levels will deliver substantial health benefits glob-ally. For example, around 80% of premature deaths attributed to PM2.5 exposure in the world could be avoided if countries attain the annual guideline levels for PM2.5.Guideline levels for specified pollutants can be used as an evidence-informed reference to help deci-sion-makers in setting legally binding standards, and are a useful instrument with which to design effec-tive measures to achieve pollutant emission and concentration reductions, and therefore, to protect human health (93).μg = microgram, PM2.5 = fine particulate matter, PM10 = particulate matter, O3 = ozone, NO2 = nitrogen dioxide, SO2 = sulphur dioxide, CO = carbon monoxide, AQG = Air Quality Guideline.a.  99th percentile (i.e. 3–4 exceedance days per year).b.  Average of daily maximum 8-hour mean O3 concentration in the six consecutive months with the highest six-month running-average O3 concentration. Note: Annual and peak season is long-term exposure, while 24 hour and 8 hour is short-term exposure.

These polygon features represent Water Quality Improvement (WQI) projects managed by the Washington State Department of Ecology. WQI projects can be TMDLs, Straight To Implementation (STI) plans, 4b projects and TMDL Alternatives. The boundaries show where the WQI project applies and is being implemented. TMDL Boundaries identified as "In Development" are considered draft and are subject to change when the project has been approved by the U.S. EPA. U.S. EPA only approves TMDLs and 4b projects. Boundaries are representations of each particular project and does not replace the official version of the approved TMDL report. Please see the TMDL Project webpage for specific information about that project. TMDL projects are required by the Federal Clean Water Act to identify pollution sources and pollution load reductions needed for water bodies to meet water quality standards. Once a TMDL project has been approved by the U.S. EPA, it enters an implementation phase where both point source and non-point source pollution is reduced through permit limits regulated under the NPDES system and through best management practices for land uses that contribute to non-point source pollution. Ecology’s water quality program works with permittees, local governments, watershed stakeholders, and residents to reduce sources of pollution to protect our aquatic resources and public health.
