Comprehensive Overview of Water Quality in Dover

Dover is a semi-rural, agricultural community in eastern Hillsborough County, known for its strawberry farms and open landscapes. The area’s water supply is a mix of municipal sources for some subdivisions and private wells for many homes and farms. Hillsborough County provides treated drinking water in more developed zones, ensuring compliance with federal and state standards for safety, including testing for bacteria, lead, and other contaminants.

For the significant portion of Dover residents who rely on private wells, water quality depends heavily on individual maintenance and proximity to agriculture or industry. While well water is a cost-effective resource, it can be vulnerable to contamination from fertilizers, pesticides, and naturally occurring minerals. Regular testing and filtration are necessary to ensure water safety, especially given the area’s reliance on groundwater.

Hillsborough County Water Quality Challenges in Dover

Dover’s primary water quality challenges are tied to its agricultural intensity, high groundwater usage, and limited sewer infrastructure. The community uses large volumes of water for crop irrigation, which can lead to over-pumping of aquifers and subsequent sinkhole formation—a concern that threatens both property and water stability.

Heavy pesticide and fertilizer use in the area poses a risk of nitrate and chemical runoff into both groundwater and nearby surface waters. This runoff can affect drinking water quality and promote algal blooms in retention ponds and local waterways.

Moreover, many properties still use septic systems, some of which may be outdated or poorly maintained. These systems, if not functioning correctly, can leak waste into the groundwater, contributing to bacterial contamination. Well water users are especially at risk if their wells are shallow or located near older septic tanks.

State and Local Efforts to Improve Water Quality in Dover

State and county officials have taken steps to address water concerns in agricultural communities like Dover. The Florida Department of Agriculture and Consumer Services (FDACS) promotes Best Management Practices (BMPs) that encourage farmers to minimize water use and reduce chemical runoff. These practices are being adopted across farms in Dover to reduce the environmental footprint of farming.

The Hillsborough County Water Resources Department also educates rural property owners on proper well maintenance and offers resources for voluntary water testing and filtration options. There are ongoing efforts to transition aging septic systems to more modern waste solutions, especially in areas with higher contamination risk.

Programs funded by state grants support stormwater infrastructure improvements, such as retention ponds and swales, which help slow runoff and filter pollutants before they reach aquifers or nearby creeks. Local schools and community groups also play a role in conservation outreach and education.

Impact of Climate Change on Water Quality in Dover

Dover is already experiencing the impacts of climate change on its water systems, with more erratic rainfall patterns, longer droughts, and increased temperature extremes. These changes affect both water availability and quality. During dry periods, the overuse of groundwater for irrigation can lower aquifer levels, increasing the risk of saltwater intrusion and sinkholes.

Heavier rainstorms, on the other hand, increase agricultural runoff, overwhelming soil absorption capacity and washing fertilizers and pesticides into ditches, canals, and aquifers. This degrades drinking water sources, especially for well-dependent properties, and can result in spikes of nitrate levels, which are hazardous to human health.

Warmer conditions also influence the growth of algae and bacteria in ponds, wells, and small lakes, posing additional threats to rural water quality. Climate-resilient practices such as drip irrigation, cover cropping, and expanded use of natural filtration systems are essential to protecting Dover’s water future.
