Samples Collected between July 2004 and August 2005

1044 samples collected by institutions120 duplicates collected by Mesa


Evaluate integrity and quality of samples collected by participating institutions

Credibility and confidence in larger data set

More rapid results for critical points

Duplicate samples used to


Quality Control

The Mesa and the participating institutions collect samples at the same location and time.

Allows technical team to check whether:

The samples are altered during handling and shipping.The samples are altered at the

laboratory.Laboratory performance.

Quality Control - Results

The results are acceptable for the evaluation.We have confidence in the monitoring conducted by the participating

institutions.


Data Evaluation

The technical team evaluates data on a monthly basis in comparison to:National standardsInternational guidelines

The technical commission meets several times per month to review the data interpretation and communicate results

Recommendations

Determine the source of drinking water for rural people.

For those that do not have access to a potable water source, evaluate the quality of the source.

Locate alternative sources if necessary.

Human Consumption


Continue to evalaute water quality in: The upper part of Qda Honda, Honda Basin.The upper part of Río Grande, Porcon Basin.The upper part of Río San José and Canal La Shacsha, Chonta Basin.

Determine whether manganese is a concern for irrigation.

Recommendations

Agriculture (Livestock and Irrigation)


Recommendations

Develop better procedures for measuring flow rates.

Standardize procedures for data quality control.

Encourage the active participation of veedores.

Improve coordination and cooperation between institutions that monitor water.

Evaluate trends in the data month by month.

Improve the communication of information to the public.
