“…Based on the testing, the datasets are assumed to be log-normally distributed. The lognormal distribution is commonly applied to stormwater descriptors (Van Buren et al, 1997;Maestre et al, 2004).…”

Few studies exist on how chloride from chloride‐based deicers is transported in infiltration‐based stormwater control measures. In 2009, the U.S. Environmental Protection Agency (USEPA) constructed a 0.4 ha parking lot in Edison, New Jersey, that was surfaced with permeable interlocking concrete pavers (PICP), pervious concrete (PC), and porous asphalt (PA). Each surface type has four equally sized, lined sections that direct all infiltrate to separate 5.7 m3 collection tanks. The USEPA acute criterion for aquatic life (860 mg/l) was exceeded in events immediately following a snow event. Concentrations of the infiltrate exceeded the detection limit (5 mg/l) year round but did not exceed the USEPA chronic toxicity (230 mg/l) after April. The chloride concentration decreased with cumulative rainfall since previous snow event, and a power regression described this relationship. In the power regression, the coefficient (b) described the initial concentration following a snow event, and the exponent (m) described the rate in which chloride was flushed through the system with infiltrating water. PC had the largest coefficient (5,664) and largest absolute exponent (−0.92), followed closely by PICP (b = 4,943 and m = −0.87), and distantly by PA (b = 2,907 and m = −0.67). The differences in release rate were proportional to the measured surface infiltration rates of 4,000; 2,400; and 200 cm/h for PC, PICP, and PA, respectively. These results will assist those who manage or regulate stormwater where receiving waters are chloride impaired.

“…This chapter presents several approaches to explain the variability of stormwater quality using the National Stormwater Quality Database (NSQD). Several analyses had been performed using this database (Maestre et al 2004(Maestre et al , 2005a. Maestre et al (2005b) for example, has shown that ignoring the non-detected observations can adversely affect the mean, median and standard deviations of the dataset, and the resulting statistical test results.…”

“…EPA (1983) found that stormwater constituents are log normally distributed. Maestre et al (2005) also evaluated the probability distributions of the stormwater quality data in the NSQD database and confirmed that log-normal distributions are very common for the constituents included in that stormwater database, with few exceptions (such as for pH). Observations from the combined database were therefore log transformed in order to use the control charts.…”
