Annual Sewer Spill Reports

For the last twelve years we have published an annual sewer spill report for Congaree Riverkeeper's jurisdictional area, which includes the Lower Saluda, Lower Broad, and Congaree Rivers, and their tributaries, using data from DHEC's Sewer Overflow Database as well as other spills we investigated. In 2024 there were more than 100 reported sanitary sewer overflows (SSO's) totaling well over a million gallons of sewage spilled in our watershed. Sewer overflows can contaminate waterways and impact water quality, creating both ecological and public health issues. River users who are exposed to sewer overflows may experience health problems including infections, rashes, and gastrointestinal issues.

For the last eleven years we have compiled an annual sewer spill report for Congaree Riverkeeper's jurisdictional area (which includes the Lower Saluda, Lower Broad, and Congaree Rivers, and their tributaries) using data from DHEC's Sewer Overflow Database . In 2023 there were 114 reported sanitary sewer overflows (SSO's) totaling 4,190,509 gallons of sewage spilled in our watershed. This is a very significant increase from previous years. Sewer overflows can contaminate waterways and impact water quality, creating both ecological and public health issues. River users who are exposed to sewer overflows may experience health problems including infections, rashes, and gastrointestinal issues.

For the last decade we have reviewed the data from DHEC's Sewer Overflow Database to compile an annual sewer spill report for Congaree Riverkeeper's jurisdictional area (this includes the Lower Saluda, Lower Broad, and Congaree Rivers, and their tributaries). In 2022 there were 118 reported sanitary sewer overflows (SSO's) totaling 369,612 gallons of sewage spilled in our watershed. This is a significant reduction from the last few years. Sewer overflows can contaminate waterways and impact water quality, creating both ecological and public health issues. River users who are exposed to sewer overflows may experience health problems including infections, rashes, and gastrointestinal issues.
Water Quality Reports

On May 28th and 29th we collected our regular water quality samples from local rivers and streams. While all the river samples were well below the state standard for contact recreation of 349/100 mL, our urban stream samples told a different story. Three sites, Smith Branch, Rocky Branch, and 12 Mile Creek showed elevated bacteria levels. These urban streams have had multiple exceedences over the last several years of sampling. It has been pretty dry lately, so these exceedences are not likely related to stormwater runoff. Other possible sources of bacteria include wildlife, sewer overflows, illicit connections, and failing septic systems.
