Nonpoint sources does not originate from a single discrete source.
Types of discharges
The degradable pollutants or called as non-persistent pollutants can be rapidly broken down by natural process.
High levels of dissolved oxygen (DO) are usually associated with high-quality water.
Illegal Dumping
Factories and Industrial Runoff
Agricultural Runoff
Chemical Runoff
Plastics
Mining
Batteries
Urbanization
EFFECTS ON THE ECONOMY
The most devastating economic fallout from water pollution, according to the Canadian Environmental Protection Agency, occurs in four main areas: Cost of treating drinking water
Losses to tourism (swimming, snorkeling, boating)
Damage to commercial fishing and shellfish harvests
Lower real estate values
Regulating pollution is a challenge for government agencies.
Regulating pollution is a challenge for government agencies.
The ultimate goal in the control of water pollution would be zero discharge of pollutants to water bodies; however, complete achievement of this objective is usually not cost effective.
- are generally done by national governmental agencies, with more detailed regulations by states, provinces, municipalities, water districts, conservation districts, sanitation commissions and others.
KEY ROLES TO REGULATE WP
Introduce
introduce national standards for some compounds.
Address
address international and interjurisdictional water-pollution problems.
Establish
establish national guidelines for water quality
The discharge into any waterways of a small number of substances has been banned or limited.
This standard is socially efficient if the marginal damage function lies above the marginal abatement cost function for all possible levels of emissions
the MAC has a positive intercept. This means that it is technically feasible to prevent the discharge of any emissions.
