County eager to study first rain’s dirty waters



CLARK COUNTY — Clark County Environmental Services says it “just can’t wait” for heavy rains to appear as it prepares to “rush out with the first rain to examine runoff carrying pollutants to creeks, streams and rivers.”

The wet weather will provide an exceptional opportunity for the department to measure pollutant levels in the ensuing runoff.

“The data really helps decide which water quality projects are needed and how existing projects are working,” said Ron Wierenga, Environmental Services program manager.

Pollutants in the runoff come from many sources including litter, motor oil, pesticides, fertilizers and other contaminants washing off hard surfaces and into local waters.

If the rainfall is enough to meet the criteria for sampling, the county will test the waters over the weekend.
