National Primary Drinking Water Regulations (NPDWRs or primary standards) are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water. Visit the list of regulated contaminants with links for more details.

Despite environmental regulations that protect the quality of streams, lakes, and wetlands, solid waste in the form of trash, litter, and garbage often ends up in these surface waters. Read more about it online.

Rivers provide many critical goods and services, including drinking water, power generation, nutrient recycling, organic matter retention, habitat for many unique plants and animals and recreational activities. Rivers in the northern Great Lakes region have a rich history, and the roles they play are reflected in the land use and vegetation associated with that region.

Dams have several benefits. They can be constructed to obstruct or control the flow of water in rivers and streams, to create a lake/ reservoir upstream of the river or to generate electricity.

Lakes are discrete, largely isolated ecosystems in which the interplay between physical, biogeochemical and organismal processes can be studied, understood, and put to use in effective management. Read more about it in this article.

Limnology is the study of fresh or saline waters contained within continental boundaries. Limnology and the closely related science of oceanography together cover all aquatic ecosystems. Although many limnologists are freshwater ecologists, physical, chemical, and engineering limnologists all participate in this branch of science. Limnology covers lakes, ponds, reservoirs, streams, rivers, wetlands, and estuaries, while oceanography covers the open sea. Limnology evolved into a distinct science only in the past two centuries, when improvements in microscopes, the invention of the silk plankton net, and improvements in the thermometer combined to show that lakes are complex ecological systems with distinct structures. This document gives you a broad overview.

This training material gives an introduction to crop water needs and discusses the influence of climate, crop type and growth stage. It also discusses how much of the crop water need can be met by rainfall and/or irrigation applications. Further, it introduces the special requirements of growing rice. Finally, it looks at the irrigation water needs within a parcel of land at the plant level.

This review discusses the dire conditions of the Aral Sea, which has seen its surface area decline by two-thirds since 1960. The Aral Sea Water and Environmental Management Project was designed to help the countries in the area solve the environmental crises.
