"TAMPA — If you looked up and down the Hillsborough River in the 1980s, you would have seen much of the shoreline reinforced with vertical walls built in an attempt to stave off erosion or, in some cases, as a convenient place to park a boat.
Back then, little thought was given to how pollutants such as motor oil, pesticides and fertilizers were impacting the river’s health. Those pollutants can harm fish and wildlife and foul water quality.
But as the Hillsborough River plays an ever greater role in the growth of downtown Tampa, the challenge of keeping it healthy is more important than ever. "
