It’s your backyard!
We’re here to protect:
The EPA & TCEQ define standards for our streams that they believe are the minimum amounts to protect the public & the environment. They’ve developed Water Quality Standards.
Aquatic Life Use [How are the Fish & other critters? Is the fishing good? Is your habitat good?]:
Recreation Use: [Want to go swimming? Boating? Play in or near the water? Touch the water without getting a stomach ache?]:
General Use [Affects everything. Makes other things go wrong if these are wrong.]:
When Assigning Causes of Impairments:
EPA’s Cause Code # 92: On-Site Treatment Systems (Septic Systems and Similar Decentralized Systems)
[From Table 4.2: List of EPA Source Codes and Source Categories]
“Onsite sewage facilities (OSSF’s) can be a source of indicator bacteria to streams and rivers. Indicator bacteria loading from failing OSSF’s can be transported to streams in a variety of ways, including runoff from surface drainage to the receiving waters or from transport by storm water runoff.” (pg 53)
OSSF’s contributed 145 billion MPN/day E. coli to parts of the watershed. (Table 25)
All loads from OSSF’s will need to be reduced from 59% - 99.7% (depending upon location) (Tables 31-32)

You are professionals! You should be treated as such and licensed as such.
The OSSF profession keeps changing and evolving. Continuing education makes sense to keep one’s knowledge current.
