Back to Enchanted Harbor Main Page

Enchanted Harbor Utility owns and operates 1 groundwater well. The system serves a semi-resort community with 96 connections. We have about 20 permanent residences the others come on various weekends and holidays.

 

A.        RAW WATER SAMPLING

We currently take 1 raw water sample per month due to our non-compliance with the Sanitary Easement rules, although we have an approved TCEQ variance.

 

B.         IN-PLANT SAMPLING

We only use groundwater and only treat with chlorine therefore we do not need to monitor anything within the plant (Page 7, TCEQ pub RG-384)

 

C.        ENTRY POINT SAMPLING

 

Entry Point

Sample Site

Plant Name

EP 001

At the pressure tap prior near the well head.

Gulf Coast Aquifer

Well 1

Oval: 20,000 Gal Ground Storage

 

  1. Disinfectant Entering the Distribution System

Our system uses free chlorine in the distribution system.

a.  Frequency:  Disinfectant residual is measured once every 7 days.

b.  Location:  At the pressure tap prior near the well head.

c.  Method:  Chlorine is measured using a Hatch Pocket Colorimeter / DPD.

d.  Compliance Calculations:     The system is in compliance if the free chlorine residual entering the distribution system is over 0.2 mg/l

 

  1. Organic Chemical, Inorganic Chemicals, and Radiochemicals.

a.  Frequency:   The TCEQ’s sampling contractor collects these samples.

b.  Location:  The contaminant concentrations for the entry point are measured at the sample tap at the pressure tap near the well head.

c.  Method:  Samples are sent to a certified lab, Victoria City-County Health Department, certification No. 48027-2001A by TCEQ’s sampling contractor.

D:  Compliance calculations:      If the concentrations of contaminants are less than the regulatory compliance, the TCEQ will inform us of the violations. Copies of any violations will be attached to the back of this monitoring plan.

           

  1. Chlorine Dioxide

We do not use chlorine dioxide.

  1. Chlorite

We do not use chlorite.

  1. Bromate

We do not use bromate.

 

D.  Distribution System Sampling

The distribution system consists of 96 connections. The system has one (1) well. The water is disinfected with free chlorine. Water is stored in above ground storage tank. The water from the storage tank feeds the booster pumps that in turn feed the distribution lines to the customers.

 

1.      Coliform Samples

a.       Frequency:  We collect one coliform sample each month. We rotate through the sample sites below.

b.      Location:    The sample is taken from outside taps from the following:

 1.    Lot 65 Redfish Ln, Jesse Wood
 2.   119 Marshal Johnson Ave South, RL & Lynn Bolleter
 3.    341 Marshal Johnson Ave South, John & Linda Koop
 4.    951 Co Rd 306, Hal Rathbone
 5.    Marshal Johnson Ave, Nelda & Chester Zwahr

            c.   Method:      Coliform samples are taken to:

            d.   Compliance Calculations:    The system is in compliance if:

§         no repeat samples are fecal or E. coli positive,

§         no repeat following a fecal or E. coli positive routine sample is for total coliform,

§         no more than one of the routine samples are total coliform positive

§         and none of the repeats are fecal or E. coli positive.

 

2.      Disinfectant Residual-Free Chlorine

a.   Frequency:  The disinfectant residual is measured at the same time as microbial samples. The disinfectant residual is also measured once every seven days, rotating through the sample sites.

b.   Location:  The disinfectant residual is measured at the same place the microbial sample is taken, plus four additional sites representing the whole distribution system.

c.   Method:  Chlorine is measured using a Hatch Pocket Colorimeter / DPD.

d.   Compliance Calculations:  The system is in compliance with the minimum residual requirement if the free chlorine residual throughout the distribution system is always greater than 0.2 mg/L. The system is in compliance with the maximum residual disinfectant level (MRDL) if the running annual average of all samples taken in the distribution system is less than 4.o mg/L.

 

3.      Disinfection Byproducts (DBPs) – TTHM and HAA5

a.       Frequency:  The TCEQ’s sampling contractor collects these samples. Letters informing us of changes in sampling schedule are attached to the back of this monitoring plan.

b.      Location:  The sample is collected from the outside top one of the 5 samples sites as the contractor wishes.

c.       Method:  Samples are taken to a certified lab by the TCEQ’s sampling contractor.

d.      Compliance Calculations:  The system is in compliance if the running annual average of all samples is less than the maximum contaminant level. The TCEQ will notify us of any violations.

4.      Lead-Copper

We take samples for lead & copper whenever we receive the bottles from TCEQ.

5.      Asbestos

The TCEQ has never mentioned asbestos to my knowledge.

6.      Chlorine Dioxide

We do not use chlorine dioxide.

7.      Chlorite

We do not use chlorite.

 

E.      Lab Approval Form

We have no lab approval form as we assume that since several cities take their samples to the Victoria City-County Health Department, certification No. 48027-2001A, and our lab is pre-approved.
