EPA Webinar – Source Water Protection and Harmful Algal Blooms

I. Using Molecular Methods to Study Cyanobacterial Blooms. This presentation introduces molecular monitoring approaches used in the detection and quantification of cyanobacterial groups and cyanotoxin genes implicated in harmful algal blooms. Results will be presented from next generation sequence analysis and qPCR/RT-qPCR methods to characterize cyanobacterial community structure, associated bacterial community, toxic cyanobacteria, and geographically localized genotypes or species. The methods study cyanobacterial functional genes associated with nutrients in toxin production, their relationship to water quality parameters, and explore drivers of cyanotoxin production using mRNA-based sequence analysis. This presentation also discusses occurrence, distribution, temporal-spatial variations of cyanobacteria, especially toxin-producers, and use as early warning systems for cyanotoxin production. II. Funding Integration Tool for Source Water: Finding a Plan a FITS. With different funding mechanisms available, it can be difficult finding…

Five decades after Clean Water Act, half of US waters too polluted to swim or fish

National News
By Amanda Brandeis; Scripps National Correspondent SAN DIEGO, Calif. — Voted into law a half-century ago, the Clean Water Act of 1972 is still far from achieving its ambitious goals. The landmark law aimed to make U.S. waters safe for swimming and fishing by 1983. It also promised to eliminate all discharges of pollutants into navigable waters by 1985. "There were really outrageous incidents of pollution that really brought the issue of water pollution to the public’s attention," said Tom Pelton, director of communications for the Environmental Integrity Project (EIP). In 1969, the Cuyahoga River in Cleveland was so polluted that it caught fire. Nearly always covered in oil slicks, industrial runoff polluted the water for decades. "And it happened before in the '50s and the '40s. So much oil…
