Stormwater Basins: How Detention and Retention Ponds Work

The main difference between a detention basin or retention basin, is the presence or absence of a permanent pool of water, or pond. The water level is controlled by a low flow orifice. In most cases, the orifice is part of a metal or concrete structure called a riser. A detention, or dry, pond has an orifice level at the bottom of the basin and ...

Variations in pH in stormwater requires treatment products

The pH of stormwater is slightly higher than that of rainwater due to the alkalinity that stormwater picks up when encountering paved surfaces. Rainwater has a pH of 5.6. A common range of pH values for stormwater is 6.5 – 7.2. [vii] Carbon dioxide and sulfur dioxide are prevalent emissions that reduce the pH of surface water.

5.4 pH | Monitoring & Assessment | US EPA

When the pH is above 7.0, the water is alkaline, or basic (there are more hydroxide ions than hydrogen ions). Since the scale is logarithmic, a drop in the pH by 1.0 unit is equivalent to a 10-fold increase in acidity. So, a water sample with a pH of 5.0 is 10 times as acidic as one with a pH of 6.0, and pH 4.0 is 100 times as acidic as pH 6.0.
