refers to the physical, chemical, and biological properties of water that determine its suitability for various uses.

water quality

is vital for human health, ecosystems, and sustainable development, requiring careful monitoring and management due to various influencing factors

high quality water

is assessed by analyzing various parameters that indicate whether water is safe and clean for its intended use.

water quality

Physical Parameters

turbidity temperature color taste odor

Chemical parameters

pH level dissolved oxygen nutrients heavy metal salinity

Refers to the cloudiness or haziness of water, caused by suspended particles. High turbidity may indicate contamination by soil erosion, algae, or other pollutants.

turbidity

Affects water's ability to hold dissolved oxygen and can impact aquatic life. Warmer water holds less oxygen and can encourage the growth of harmful bacteria.

temperature

Natural water should be clear and odorless and tasteless. Any unusual color, odor, taste could suggest contamination.

color taste odor

determines its acidity or alkalinity. Acidic water can cause corrosion of pipes and introduce harmful metals into the water while basic water can give water a bitter taste and cause scaling on pipes and appliances.

pH level

is crucial for aquatic organisms. Low levels of dissolved oxygen (often caused by pollution) can lead to "dead zones" where aquatic life cannot survive.

dissolved oxygen

Excessive nutrients, often from agricultura runoff, can cause algal blooms & eutrophication, leading to the depletion of oxygen and harm to aquatic ecosystems

nutrients

Metals like lead, mercury, and arsenic are toxic even in small quantities. They can enter water through industrial pollution or natural leaching from rocks and soils.

heavy metal

The concentration of salts Red Sea-40 pot in water can affect its usability for agriculture and drinking. High salinity levels can be harmful to both humans and crops

salinity

Biological parameters

microorganisms

Pathogens such as bacteria, viruses, and parasites are key biological contaminants. The presence of harmful microorganisms can lead to 100 75 50 waterborne diseases like cholera, dysentery, and gastroenteritis.

The Philippines has abundant water resources, including rivers, lakes, groundwater, and a long coastline. However, water quality varies due to pollution, inadequate treatment infrastructure, and regional activities like agriculture, industry, and urbanization.

water quality and availability in our community

The primary agency responsible for water quality in the Philippines is the Department of DUCT Environment and Natural Resources (DENR) through its Environmental Management Bureau (EMB), which monitors water quality, sets ment of standards, and enforces laws. The Department of Health (DOH) also safeguards public health regarding water quality. Additionally, the National Water Resources Board (NWRB) manages water resources and regulates usage for sustainability

regulatory bodies in the philippines

In terms of laws, this is the main legislation that governs water pollution control and management. This law aims to prevent and reduce pollution from various sources such as industries, households, and agricultural activities, and it promotes the protection of water bodies to ensure clean water for everyone.
